  • My biggest success was that we finished our robot on time and it was the way that I wanted. When we were planning out our robot, I thought that I would be really challenging to complete this project since we were not really good at programming and I was not good at crafting. Although, in the process of making, I noticed that it was pretty easing because realized how teamwork is really important.

  • My biggest obstacle was the programming and the planning part. We were really lost when we started planning because we had no idea how to start the project. However, we got inspiration from robots that others made, and eventually, Alice came out an idea that we could make a dinosaur.

  • Skills that I learned from this unit was that I now know a little about programming.

1)What are polymers & how are they made?


Polymers are made out of chains of molecules bonded together which are called monomers, and this chain is often made of carbon and hydrogen. Some polymers bend and stretch like rubber. Others are hard and tough, like epoxies and glass. Polymers are used in almost every area of modern living. Grocery bags, plastic, soda cans, toys, and food packagings are all made from polymers. For our experiment, we will be making polymer out of polyvinyl alcohol, baking soda, and shaving cream to create a type of slime that can clean keyboards.


2)What are the synthetic materials, and where do they come from?



One of synthetic material is polyester, this is a synthetic fiber derived from coal, air, water, and petroleum. In order to turn natural resources into synthetic resources, it has to go through a chemical reaction between an acid and alcohol. During the experiment, molecules have to combine to form larger molecules and when this process repeats, it eventually forms a large chain.

Another kind of synthetic material is Rayon, it is a material that is made from the cellulose of wood pulp or cotton.
