Transcript of Polymers
by Addie Collier & Savannah Wozniak Mr. Beringer showed our class polymers at the beginning of science class. He told our class that polymers grow in water.
Our question is…
Do polymers absorb different liquids, like oil and colored water; and how do they grow in different temperature? Our hypothesis is…
Polymers will absorb oil and colored water. Polymers will grow fastest in hot water and slowest in cold water. Hypothesis Research What is a polymer? Materials oil crockpot ruler cold water, Hot water, room temp water spoon 4 test tubes labels food coloring The Question Procedure Results polymers (magic marbles) Conclusion Future Direction Some of the things we found while we were researching is that polymers are actually long chains of molecules. These small molecules are called monomers."Mono" means one in some other language. Poly means many. The way that the polymers form is by monomers crashing into more monomers and more monomers until they turn into a polymer. Depending on the way they crash together, the monomers will make a slightly different polymer. To do this experiment, first pour hot water into a crock pot. Put one polymer in. Pour cold water in to a test tube. Put in a polymer. Pour red colored water in to a test tube. Put a polymer in. Pour oil in a test tube. Put a polymer in. Pour room temp. water into a test tube. Put a polymer in. Let them sit for one hour. Check size with ruler. Then do 4 hours, then 12, then 24. After 4 hours, this is what we saw:
Grew but lumpy. Grew and smooth. Grew but changed color. Some grew some shrunk some like this one, broke into pieces. Didn't grow and became soft. Here's our data: We did the experiment twice. Savannah's mom taught us how to make
a graph: Our conclusion is that polymers will grow and absorb in colored water. They will not grow in oil. They will grow fastest in hot, then they will break. They do not grow slowest in cold. Other Questions:
Will polymers grow in running water like the Mississippi river?
Will they grow in salt water like the Atlantic? Sources:
