Diffusion Experiment Reflections - Period 3

Here is the place for you to post your reflections on our diffusion experiments. Since it's a reflection, you will be sharing your experiences: what you liked/didn't like, what you learned, what surprised you.

Be sure to think through all the phases of the project:
  • Designing an experiment
  • Having your experiment reviewed by another group
  • Working with your partner
  • Conducting your experiment
  • Preparing your presentation
  • Sharing your work with others

You all did a really good job with the projects. I look forward to reading your reflections.

I liked this experiment because we could choose any way to show diffusion. I thought it was really fun making up a way to show diffusion then watching it. My partner and I decided we were going to show diffusion by dropping mentos into coke.

Working with a partner was a lot of help. I like it a lot more then working by myself. I like it a lot more because everyone understands things differently and have a different view of things. Which I think made our experiment more creative.

For our experiment we needed diet coke, mentos, and a stop watch to time how long the diet coke stayed up in the air after we dropped the mento in. It was easy to get the materials because all we had to do was go to CVS. The hard part was remembering to bring them in, since we both kept forgetting them at home.

When we conducted the experiment everything went pretty smoothly. Since we had all the materials it only took us a day to do the experiment and collect all the data. We went outside and placed the diet coke in the middle of the blacktop then put a mento into it then backed away. Then we timed how long the coke stayed in the air before settling back into the bottle. We were surprised that it took so long for the mento to defuse in the diet coke. We predicted the coke would shoot up out of the bottle after one second instead of five.

My partner and I made a Voki for our presentation. We typed my cell phone number into the Voki website then they called us and we recorded our presentation. It was hard to do because we had very little service but it worked out okay.

When everyone listened to our presentation on the Voki it thought it was funny how we sounded. I think we did a pretty good job, except the ending sounded kind of weird because we ran out for time and didn’t want to make a whole new Voki for just one more sentence.

Reflection

I would’ve never thought that dropping Melons and exploding marshmallows was a way to show diffusion. I had a fun experience conducting an experiment of diffusion with my partner, from actually doing the experiment to presenting it with a poster and a power point. We designed the experiment with the scientific method/lab. To do the experiment we followed a data table that we drew. For the melon experiment we filled in the chart with the length of how far the melon diffused on the ground. For the marshmallow experiment we timed how long the marshmallow was in the microwave, and the length and width it was when it came out of the microwave.
Working with a partner was really fun and helpful. I thought that my partner and I worked really well and hard together. Working with a partner was helpful because we both divided the work of typing up the labs equally and then we worked on the presentation together. The materials we used for our experiments were: marshmallows, honeydew melons a yardstick and a microwave. For the presentation we used a school laptop and a poster that my partner and I made. For our presentation we made a poster board with our labs on them and pictures of our experiments, we also made a power point which explained how we conducted our experiments and what the results were and why. I think that others found our presentation very explanatory of what we did and put together.
Throughout the process of the experiments we didn’t end up needing to make any changes for our presentation or for our procedure. Over all I thought that this project (diffusion experiments) was a great and fun experience

Diffusion Experiment

I had a lot of fun designing, presenting, working with a partner and conducting a diffusion experiment.
When we were designing our experiments, it was pretty fun to come up with wacky and cool ideas to use. I think that both partners should be required to come up with ideas. I felt like I came up with a few more ideas.
It was cool when we had to review another groups experiment and they had to review ours. We got a lot of feedback on our project that helped us improve it. I liked looking at other peoples projects and helping them make theirs better.
I like working with partners in general, but I did not particularly like working with my specific partner. I felt like I did most of the work and they didn’t concentrate that much. It would help if people were assigned equal amounts of the assignments. It’s a lot better to work with a partner of your choice because you know you will work well with them.
Actually doing the experiment was a blast. It was really fun to time it and almost cheer it on as it went, and then show it to other people. I wasn’t in school for one of the experiments, so it was hard to figure out what happened. One of our experiments didn’t work at all like we had planned it would so it was hard to put that part into our presentation.
When we preparing the presentation, I did NOT like the way we worked together. We hardly even worked together. I think that my partner did try, but it was hard to talk to them about what I was working on. One of the things they made got lost and so all the time they put into it was pointless.
The way we shared our work was okay. It was kind of hard to sit still and read each presentation so you kind of had to skim through each one so you could get to all of them. I only fully read a couple.
In general I think that this experiment was fun because it was totally hands on.

The whole project was really fun to do. We learned a lot of things that you can do with diffusion, and we understand it more now.
It was fun working with partners, except sometimes it was hard because we had to depend on the other person to bring stuff in, contribute to our research, and be there on time so we can work productively.
It was really fun actually DOING the experiments because…well…it ALWAYS fun to do experiments! I think it’s easier to learn something when you are testing it right in front of you.
It was fun putting everything together, making a voki and PowerPoint and making it just as we want to show everyone.

Diffusion Project Reflection

Well, before we started anything, we actually had to think of an experiment that had to do with diffusion. My partner and I chose lemonade powder packets and air fresheners. Once we chose the experiment, we had to design it. Designing the experiment was sort of hard because you have to be pretty sure that your experiment is going to work, you have to be pretty sure that the experiment your designing has to do with diffusion and you had to make sure your design was detailed and your design was not impossible to understand. The easiest thing about designing the experiment is you don’t know that it’s not going to work. Once you actually conduct the experiment, it could be wrong and you’ll have to totally redesign it. Poor scientists!
Having your work reviewed was all right because it was good to know what other people thought of your experiment and how you were going to conduct. Maybe you seriously messed up in one spot and you were so excited about doing your experiment that you didn’t even notice. It was also good to read other peoples’ experiments because it sort of automatically made you want to compare it to yours and if theirs was better, it made you want to change yours.
Conducting the experiment the most interesting and fun part of the project. It was so fun just being able to stop the stopwatch when you smell the air freshener or pouring boiling water into a water bottle and almost burning your hand off. It really makes you feel like a real scientist! It was also great watching the other people do their experiments because you got to see what they thought best-showed diffusion. It was also cool seeing a marshmallow grow. The only thing we could you done better with conducting our experiment was pouring boiling water into a plastic water bottle. It also melted onto my hand and that would have hurt, a lot.
Working with my partner was a great experience. She really understands science and how diffusion. It was also great because when we needed to bring in materials she could bring in half and I would bring in the other. The other great thing about working with a partner is when you don’t know what decisions to make they always help you. So thanks partner!
Our presentation was pretty easy to prepare because all we really had to do is explain what we did in an attractive, funny way. We made a power point in a few days. We thought that we were going to present it to the whole class, so we didn’t put in everything and we were just going to talk about it. But, as it turned out, we were just reading each others so it might not have made total sense, but it was still really detailed and colorful.
Sharing our presentation was great because when ever someone read it they laughed or smiled or looked interested. It felt really good that people thought your experiment was good. I also loved reading other peoples’ experiments because they were really funny, cool or interesting.
All in all I had a great time doing this project because it really gave you the thrill of being a scientists. The other thing it did, it made you realize how hard scientists have it. If they mess up, they have to start all over. I know that happened to us. Anyway, I really hope we do something like this again.

Designing an experiment may seem easy but to tell you the truth, it wasn’t all that easy especially if nothing went your way in our experiment that was the case. We had planned to record and get over it but nothing had gone the way we wanted it to. Our first experiment was two lemonade mixes dissolving. Anybody could have said that this experiment would be easy because you know those lemonade powder dissolves almost immediately But for us it wasn’t like that. One of the lemonade mixes took up all day and that had knocked us off our plans. We had to wait and then the next day we had to record our data and we were already late one day. In our second experiment, it wasn’t much like what had happened before. Our plans had work out the way we wanted it to go. We set up our area, started our timer and recorded after.




Having others looks at your work is scary because they might have not liked it but it’s good in a way. It’s good in way because it gives you other peoples advise on to make it better and it gives you other people’s opinion other than yours and your partner’s one.



Working with my partner was great. She was very dedicated to getting everything done. She worked hard at it and she was very reliable. When you work with a partner it gives you company but it also gives you more responsibility when someone else is relying on you.
Conducting our experiment has been hard and difficult, as I had said before. We went through Experiment # two in a breeze but Experiment # one was mostly our main problem. We started to record and everything was set until one of the mixes didn’t dissolve completely. We started to panic but lucky after 24Hrs. the powder had dissolved completely.



Preparing our presentation wasn’t that hard. I mean it was but not as difficult as conducting it was. We made sure that we came in every lunch period to finish and to improvise it better than it already was so that we were set when it was do. We made sure to include detail, explanations, and diagrams. Over all I think that we could have done a little better and made more creative but we met every requirement that we had to do.
Sharing our experiment was cool. We go to see theirs and they got to see ours. What they thought was very important. Their compliments or advice could and will help us do even better in our next project.

I think that the diffusion project was really cool. I liked making up our own way to show diffusion. It was fun to put diet coke and mentos together and make an air soft gun and test it. I like to work with partners but I don’t like to rely on them to bring something into class. Designing the experiment was interesting because we took our ideas and mashed them together to come up with an experiment. Conducting the experiment was the best part, we got to test diet coke and mentos and shoot an air soft gun. Our experiment wasn’t reviewed by another group. In preparing the presentation I did the poster and my partner was supposed to do a video clip but didn’t so all we had was my poster. It was good to share our work with others so we could have more opinions on our work

Science Diffusion Experiments Reflection
by dance4peacexo

In science class we had the opportunity to design two experiments showing diffusion. My partner and I decided on two experiments we thought sounded fun and explained diffusion. One of our experiments was dropping melons from high distances and measuring the splatter of the melon. This experiment shows diffusion because there is so much pressure in the melon when it hit’s the ground, the molecules inside need more room so they break through the surface of the melon causing the inside of the melon to diffuse. Our other experiment was taking three marshmallows and putting them in the microwave for three different times. This is an example of diffusion because there are so many molecules inside the marshmallow when it is getting heated, they cause the marshmallow to expand in size by trying to get out. When we did this experiment, we measured the width and length of the marshmallow when we first took it out of the microwave.

Having our experiments reviewed by another group was good because we got advice on things to change and what really makes sense. It was also a bit hard though because we didn’t have our experiments typed yet, so they were basically our rough draft, and they weren’t edited and they were pretty messy but this was also to our advantage because we got editing help early on in drafting the written lab. The partners who reviewed our work gave comments on our hypothesis. Overall, getting our experiments reviewed was great because we were so excited about actually doing the experiments, we messed up on some things and the partners reviewing ours really helped us. I liked reviewing other peoples written labs because it was good to look at other experiments and comment on them.

Working with a partner was really fun because you could split up the work and you could work together which makes things much more fun. Sometimes it is hard to agree with a partner but my partner and I didn’t disagree very much. We both agreed on the experiments, who got the materials, we split up some of the work equally and we worked together for some things. It was really fun to conduct the experiments with a partner because we both could work at the same time so it would go by much faster and be more enjoyable. I like working with a partner much better than alone because for example, one day in designing the presentation I was sick and not in school but my partner started and got pretty far in the presentation so I didn’t have any catching up to do.

Gathering the materials was pretty simple because my partner and I evenly divided up the materials we needed. We needed marshmallows, three honeydew melons, a sharpie, a tape measurer and a poster board. The marshmallows were for the marshmallow in the microwave experiment. The honeydew melons were for the melon project. The sharpie was to define the melons by names. The tape measurer was for measuring heights for the melon experiment and for measuring the length and width of the marshmallows. The poster board was for our presentation. All we really had to do was go to supermarkets and other stores around town.

Conducting the experiments was really fun. First, we conducted the melon experiment. We went outside to the back of the school where recess is. We found three high heights, 20 feet, 18 feet and 6 feet. We dropped each melon and something not planned happened. It was really icy out so the melons just broke in half and slid away from each other each time because where we dropped them, the ground level was on a slant. We recorded the width of the splatter and the height of the drop in the data chart. Overall, this experiment went pretty well except for the ice. Second, we conducted the marshmallow experiment. We got a microwave from Ms. Fontana and put each marshmallow in one by one. The first marshmallow we put it in for 30 seconds. The second for 45 seconds. The third for 60 seconds. After each marshmallow was done, we took it out of the microwave and measured the width and height of it and recorded it in the data chart. This experiment went exactly as planned, except we were planning on the marshmallows exploding (which did not happen). We didn’t end up changing anything about our experiments. Overall, our experiments were pretty easy to conduct, except for the ice, and I really thought they would be harder.

Putting together the presentation was fairly easy. My partner and I made a power point in school and a poster at home. The power point had all of the information in it and was very self explanatory, in my opinion. We added pictures to it and had lots of detail on how we conducted our experiments, the results and why. We presented our power point on a school laptop. The poster, we made at home. On the poster, we put our written labs and pictures on it. Our poster was very colorful and a lot of fun to make. Overall, presenting our experiments was probably the most fun job, for me, because I like being creative and making things and it was even more fun working with a partner.

Having others see our work was enjoyable because they get to see how much work we put into our experiments and presentations. It is like all of the hard work paid off. I thought our presentations were enjoyable to look at and to read because it was very colorful and caught peoples eyes and because it was organized and neat. I really felt good when I saw other people looking at our presentations. Overall, this experience was really fun and taught me a lot about diffusion and how to work well with a partner.

My Science Review

I loved the project it was so fun. My project was the one with Opps should i say it??. I loved it that i got to actually do the ____ and ____ instead of watching it on youtube or something. I think that the designing of the project was very easy. We got the ideas immediately. I like working with partners rather than working in groups. I am also fine with just working individually. I think the materials were easy to get, all we needed was balloons, a stopwatch, mentos, and 3 bottles of diet coke, and the outdoors. Conducting the experiments was fun. I think we should have done the 6 mentos better because i couldn't fit all of them in at once. Our changes were either we would have to do the height of the fountain of coke or the time that it stopped spewing so we decided when it stopped spewing. I love having people see my work, I see it as a confidence booster and i like to show off.

HaHa lol

ps: ugggg mine looks sooo short to the other ones!!!

Diffusion Experiment Reflection
By potatopotahto

Conducting and presenting my diffusion experiments was a very interesting process. It had a lot of parts to it, such as designing the experiment, checking someone else’s work, working with a partner, conducting the experiment, putting together a presentation and seeing everyone’s final product. It had a lot of work involved, but it was really fun and it taught me about the scientific method and how scientists work.
The first thing we had to do was design the actual experiment using the scientific method. I think that the exact scientific method was very helpful because all you had to do was fill in the blanks. Sometimes it was difficult to get the wording correct for the procedure because it had to be exactly what you needed to do. We had to change our design for the experiment a few times, but in the end I think that the design was very good.
After we finished designing our experiment we checked someone else’s work. I think that it was helpful because when you write your own lab, then you know what is going on and think that everyone else will too. But when someone who has never seen your work before looks at it, they may have no idea what you are talking about! Also, seeing another kid’s point of view is very helpful.
Working with a partner is not always easy. My partner, Iso, was a very good worker and helped a lot throughout the whole process. Sometimes, we had different ideas about what to do, but we compromised and the experience turned out to be great. I think that this project really took two people because there was a lot of work involved. We both took on the job of getting the materials for our experiments. Iso got the lemonade powder and I got the air-freshener. We both brought water bottles for the lemonade powder experiment. Also, it would have been very difficult to type both labs by myself. We split up the job, so Iso did one lab while I did the other. Then, we edited them together. I think that we worked very well together.
Conducting the experiments was really fun! Iso and I followed our procedure and we collected data. For the Lemonade Packet experiment, we poured the packets into water bottles at different temperatures. We had to change our procedure a little bit because when we poured the powder in, it just settled to the bottom. So, we changed our procedure to shake four times at the beginning. Once we did that, the experiment worked very well. I learned that all experiments don’t always work as well as you thought or they don’t even work at all! I also learned to not pour boiling water into a water bottle (it almost melted). For the air-freshener experiment, we stood five feet away from each other and I sprayed the air-freshener. Iso timed how long it took until she could smell it. I had a lot of fun testing both of our experiments.
Putting together the presentation was very fun, but also a little bit confusing. I loved making the PowerPoint and having fun with all of the transitions and backgrounds. The confusing thing was that I thought that we were going to present them out loud to the class. Iso and I planned out presentation so that we wouldn’t have everything on it and we would say what we did not have. I also was not sure if we should just put our lab on the PowerPoint or if we should group things together and talk more about what we learned and our experiences. I thought that it was a little rushed for making the presentation and it could have been clearer about what we were supposed to do.
Seeing other people’s work was very interesting because it gave you the chance to seeing what other people had done and what their ideas were. It gave me ideas for what I could do better next time. Everyone has a different style of presenting and I loved seeing what they were. I think that the Voki was a cool idea and I would have done it, but we did not have enough time. Overall I think that this was a successful project and I loved doing it.

My science experiment

I really liked this experiment because me and my partner got to choose our own way how to show diffusion, If we had gotten an assignment and wouldn’t of known how to show that it would of ruined the whole project for either me or my partner.

One of my Experiments was dropping a water balloon down from 20 feet up high and see how long I would take for the water to defuse but then when we actually did the experiment it didn’t turn out the way we planned it, so we changed it up a little to find out how long it would take for the water balloon to drop from 20 feet and how long it would take for it to explode. Our diffusion project really did not come out as what we thought but we had thought of another way to teach how diffusion works.

Our other Project was to see how long it would take for one pack of hot chocolate mix to diffuse into the hot water, What I liked about this experiment was that when we where don’t with the experiment we got to give some hot chocolate for the whole class. This diffusion experiment turned out 100% the way we thought it was going to turn out.


What we needed for the water balloon experiment was 4 balloons, water, and a stop watch. Also what we needed for the hot chocolate experiment was about 27 packs of hot chocolate mix, hot water, a thermometer and cups.

I thought It was a lot of help to have a partner that was organized like I have been so it would be easier for everyone to get the project done and get it over with.
I also thought that it was really fun to do the hot chocolate experiment because we got to drink it after wards and it turned out just like we wanted. I didn’t really like the water balloon one because it was harder then we expected and didn’t work as well as we thought.

I would definitely do this experiment again.

Reflection on Diffusion Experiments



Designing the experiment was easier than I thought it would be. We only had one problem… We only had trouble with our method of testing. First, we were going to test our experiment on how hard it would become, but that did not work well. Next, we poked holes in the caps of our water bottles so that way they would blow out what ever we would use to clog the holes. If we thought of something else, we probably could have gotten better results.
In my opinion, it was better working with a partner than alone. It was fun when we were setting up for the experiments and when we were both ready to start the experiment. If I worked, alone it probably would have taken me a lot longer to put everything together
We had no problem gathering materials. We each gathered all the materials for the experiments. First, we choose which experiment we wanted to get the materials for. Then the next day after we decided we had brought most of the stuff in. We only had a delay because the lemonade mix we were going to use for our experiment was used make lemonade outside of our experiment. So then, we had to get some more lemonade mix.
We conducted our experiments with-in a few days. It did not take too long to do each experiment except for the clean up and as I said before we had a little problem with our method of testing. Besides those two things, it was somewhat easy.
We both used Power Points for our presentations. We were finished with them by the second time we went to the computer lab, all ready to explain our project. We had no difficulty that this time unlike everything else we had already done.
When we let, other people see our work I think quite a few people liked some of the stuff we did within the Power Point. For example, like adding custom animations and sounds to each slide. I had a lot of fun doing this, and I think we should do something like this again, but maybe a little different just to change it up.

Diffusion Project Reflection

I had a great learning experience that was a lot of fun, but still required a lot of work. Working with my partner gave me a huge advantage because we would split the work so it felt like there was less work to do. Designing the experiment was a lot of fun because we could come up with the most creative idea that still made a good example of diffusion. Along with that, we had to also bring in our own materials. For example some people brought in lemonade or hot chocolate mix. I had to bring in mentos and find rusty cans of febreeze and oust which took me a little while. Conducting the experiment got sort of really hard sometimes, because we had to know when to make a change and what kind of a change the experiment would need. It got even harder when your experiment didn't go as planned or your hypothesis was way off, but in the end we actually learned a whole lot more that way. Making the presentation was probably the most fun and the easiest part of doing the experiment because we had to make our own voki and record ourselves on our phones, and it seemed more like a game to me than work. Showing the presentation was almost embarrassing because our voices sounded completely different and everyone would laugh, including us. I thought it was a really fun and creative way to learn diffusion and it was really neat to see how scientists work.

Project Reflection
By Green101
I thought the project was a good way to act like real scientists, but if I could have changed some things, I would have. I liked a lot of the things we did but then, I didn’t like some of the main components
I liked the power points; they were a lot of fun. They also showed information pretty well. I would have liked to do presentations with them in front of the class on the smart board. Designing an experiment was really hard, since my partner and I changed our experiments about 3 times each to completely different experiments. So another group checked the first two only, that wasn’t a good use of time. My partner was a good worker and we worked well together, although we did have arguments, we always ended up laughing.
I thought conducting our experiment wasn’t really that hard, I just kept forgetting to bring the stuff in. I think our second experiment was easier than the first although we kind of skimmed over both of them since we were tight on time. Preparing the presentation was really easy, all we had to do was make the power point and print the Scientific Methods. Sharing our work with others was difficult because of technical difficulties and then we didn’t really have enough time to look at others. Some other things I thought we should change is that I thought we should have had more time but then again I always want more time.
I learned more about the scientific Method than diffusion in this project actually and every task that needs to be completed to finally call it done, you never run out of work. Nothing really surprised me in this project, I kind of knew everything about Diffusion and The Scientific Method.

I think me and my partner had some great experiences together. Working together was fun, finding out what to do as an experiment after me found out we could light gasoline on fire was kind of hard but we kept on thinking and finally came up with something. Designing the experiments was not that hard, the first experiment just came to me simply after. Working with my partner was fun and hilariously a good time we had lots of laughs and when each other had a question we each answered it right away. Gathering materials was extremely easy this time, usually I’m really bad with gathering materials. I owned most of the materials so it was easy to find them.I definitely needed to change this experiment but not more than once. It was when I was doing my experiment I thought it needed a little tweaking. The presentation was fun, going up to the lab for help was awesome with the other people there it made it funner. I liked writing/typing it up and using PowerPoint. I thought it came out pretty well I also thought it could have been a little better thought but I still thought it was good. I’ve always been nervous with showing my work with others or others seeing my presentation but this time I felt comfortable because we all went around looking at each other not presenting it in front of the whole class. I never really thought about what other people were saying about my presentation, like I said before I felt really comfortable.

Reflection

I think that this is one of the best experiments we have done all year. I think that it was a great learning experience because we had the chance to design our own experiments and then follow them out. Some things that I would have changed was the way that I preformed my experiment. Working w/ a partner was defiantly a good idea because the responsibilities are split up between you. If were to do this again I would choose a more sophisticated experiment.
