Our Capstone movie is about SDG goal #6 Water and Sanitation. Our movie includes information on water and sanitation is beijing as well as at ISB and how ISB provides us with clean water. It shows us why and what we should do to improve our water. The process of making our movie didn’t take that long. We first planned out the scenes we wanted in our movie. Maxim wrote the script and we started to film the next day. After we filmed the scenes, we found background music and then started to edit and cut the clips. Recording us speaking didnt take long. Since i have made movies using imovie, it wasnt that hard cutting and splitting the clips. We were able to finish everything in time because Maxim and I were able to complete our job we were assigned to eachother. We were able to work together and use our time wisely. I was able to finish editing in time and Maxim also found many of the videos and we did all of that in a small amount of time.

Since we didn’t have enough time to make a variety of prototypes using different materials we just went with the one we made that had our ideal physical properties. We first tried making the gelatin melt completely so it would look clear and like jelly but after the gelatin hardened, we found out that the substance was not good for using it as a flower pot/ base. It would rip easily when we tried to mold it. It had the physical properties of jelly. The second one we made, which is our finally product we decided it would be made out of, was made from not completely melting the gelatin. The properties of this one was hard and sturdy. The color was still yellow, but it was strong, so we decided the material of the flower pot would be made out of this. The limitations of our product might be the temperature it can be in, when it will biodegrade, and if it is waterproof. We are not sure about those things because we had no time test it and to collect data. Right now, we don’t have enough data to provide an answer to those problems. The thing we wanted to focus on if we had more time is making the melted gelatin into a mold of the flower pot. The clear one is the one we tried to make first and the second one is what we want the flower pot to be made out of.

Claim: Our second prototype, the yellow one made out of gelatin, was the most successful.

We cannot determine which one was the best with the amount of prototypes we have right now. The second one was the best out of all the protoypes we made includig the one with glue, borax, and guar gum. From the texture of the gelatin to what it’s like when we stretch it, it was the closest to what we wanted. We choose that as our final material becuase it was 100% biodegradabel which was sustainable, but the others we made either had borax and glue, or just not sturdy and strong enough to hold up a flower.

Gelatin is made by boiling skin, tendons, ligaments, and/or bones in water, and is used is prosucts like soap amd shampoo. Gelatin is also used to make jelly. Gelatin is made out of long protein strings and the protein it’s made out of is collagen. Gelatin also contains nitrogen which banefits the plant.

5. The design process was hard because you had to gather information, make your polymer, and test it to see if it works. It was hard coming up with accurate measurements and the recipe for the right texture of your ideal polymer. It was also hard for us because our team changed our idea so with less time, it was hard for us to make and test our polymer. After that, we made the ppt that we were going to share to the Dream on Team. I think we spent the most time on trying to make our polymer because it was hard for us to get the right texture of the material it was going to be out of. When we presented our product pitch to the Dream on Team, everything went well I think for me. We added the details of the polymer and who will be buying it. We also filled up some of the gaps and limitations of our polymer. I think next time we can provide an actually model of our product with a flower inside. I think the sustainability of our polymer is good because 100% of our polymer is made from biodegradable material and gelatin also benefits the plants. Next time, we need to run tests to actually back up the fact that it’s biodegradable, but I think that our flower pot can reduce plastic if it’s made in a good quality.

We want our polymer to be strong but flexible meaning that it will contain a large amount of dirt while being able to be sturdy so it won’t tear or break easily. When you hold the flower pot I your hands, the feeling of the polymer would be somewhat like jelly but also like rubber. We will try to use different biodegradable products to try to make a flower pot. We thought of using gelatin first and see if it will have the certain properties and texture of our ideal product. After that, we also wanted to try other substances that had a product similar to the product gelatin made. We will test these prototypes by planting a flower inside and recording the number of days in order for it to biodegrade. Another way to test its quality is to leave it in different temperatures and see if it changes. We might not be able to test it but form the materials we used pare going to be biodegradable. As you can see in the pic above, that is a picture of our model of the our real product. After it dries, the texture was what we wanted, but in order to make it environmentally friendly, we decided to change the recipe and use more biodegradable substances.

Our polymer is a flower pot. Unlike other flower pots, it’s biodegradable so you can plant it into the dirt and it will biodegrade. The goal of our polymer is to not only be a flower pot but also reduce common plastic flower pots people use every day. We choose to make this polymer because in our everyday lives we see plastic flower pots around markets and shops that sell flowers. The flower pots break easily due to the weight of the dirt. After it breaks, people would throw it into the trash can. Our polymer can hold the dirt and the flower without breaking. Our polymer is made out with gelatin and glycerol. Since gelatin is used for making jelly, the texture will be not that sticky and crisp. It will be in like a jelly like state, making it rubberlike. Our polymer will reduce the usage of plastic flower pot and plastic because it’s biodegradable. The flower pot won’t break because our flower pot would be flexible and stable at the same time. Our product will specifically be for those who sells flowers. Our product will also be useful for people who own a garden, arboretum, or farm. We think gelatin would be the best base polymer. Gelatin can form into something that looks like plastic but it’s not. It’s also very flexible and it won’t break easily.

  • My biggest success was…

The biggest achievement we made during this process from building the robot to programing it and then finally sharing it, is probably getting our kangaroo to work in a short amount of time. We made mistakes throughout the process of making our robot so we made a lot of adjustments, but were able to code on time.

  • My biggest obstacle was…​

Our biggest obstacle was probably organizing the time to work on our robot. Since we had trips, we got less time to work on it together. We had to find a time where we could work on it after school.

  • Skills that I learned or developed were…​

When we were building the robot, I learned how to connect the different perices in different ways using different materials. I developed my coding skills when we were trying to make the nose move. I also learned how to connect the different wires to the arduino.
