Polymer Journal #4

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.

Where in our solar system should NASA focus future missions?

Claim: In the future, NASA should focus more on exploring in Saturn’s rings, on a moon called Enceladus.

Evidence: In the Newsela article about searching for life beyond Earth, they found out that in Saturn’s rings, they found a moon that may contain life. NASA found hydrogen molecules in the geysers of Enceladus. The chemical reaction and tart life for microbes. “We now know that Enceladus has almost all of the ingredients that you would need to support life as we know it on Earth,” Linda Spiker said. Scientists found a lot of hydrogen which living organisms need so there may be life or contain life there. Hydrogen and carbon dioxide under means that undersea microbes are producing methane gas. This is what microbes do deep below Earth’s oceans.

Reasoning: NASA should focus more on exploring Enceladus because if one day Earth can’t sustain life, we will have another place where we can go, since scientist have found things that contribute to sustaining life. Enceladus has many natural fountains. Water is an important thing we need in order to survive.  This can not only help us in the future, but this discovery can also help us advance our knowledge about outer space and our solar system. This can also show that there is life outside of earth.  “We still have a long way to go in our understanding,” said Seewald, who was not involved in the study. “Future missions to explore oceans beyond Earth will answer many of these questions.”

 

 

How big is our solar system?

Our universe contains 10 planets and billions of stars. Our solar system has 10 planets. They are separated in different groups according to their characteristics. When we did the activities in the last two days, we learned about the diameter or the actual planet and the actual distance from the sun. We converted the diameter into centimeters so 1 cm=50,000 km and we converted the actual distance from the sun, so it was actual distance divided by 100 equals the scaled distance. We took those scaled measurements and went around ISB mapping their distances. Even though we know a lot of things in our solar system, there is still many things outside we haven’t explored.

The planets in order, from the closest distance from the sun to the furthest, starting from the Sun is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto (if you count that. As a planet). The planets Mercury, Venus, Earth, Mars, all have similar characteristics, so they are in a group called terrestrial planets. Gas giants, Jupiter, Saturn, Uranus, Neptune, are made out of gas. That means their density is less, but they are bigger than terrestrial planets. They are also further away from the sun.

From our experience when we were mapping the planets outside on the field and the track, we used the scaled distance (meters). It took the whole class time to map it and when we got to Mars, it took a long time to walk to Jupiter. We had to walk another 110 meters. Even though it was the scaled distance, it took a long time. We had to run starting at the dome to the baseball field. After that, as we mapped the rest of the planets, we went around the baseball field and walked around the track once and then finished it at the cafeteria door, the one close to the dome. From this, it changed my mind on how big our solar system is. Since we scaled it, it took a long time but if we didn’t scale it and went with the actual number, it would take a long time. Mercury is 11.6 meters away from the sun, and the furthest planet from the sun is Pluto, 1180 meters. The actual distance from one planet to another is a very large number. It would take us a long time get to another planet not close to us. Our solar system is big, but it isn’t the biggest thing.
