We have three 6th grade Science classes and two 8th grade Science classes blogging here from the Pacific Northwest in Chimacum, WA! Sixth graders are learning a bit about Mt Saint Helens, environmental science through fresh water ecology, and physical science this year. Eighth graders are learning about life science this year. Please join us as we learn Science by exploring our world.

Our polyacrylate experement!
This week during science we have been doing an experiment. My group is doing an experiment on polyacrylates! We put the polyacrylates in 5 different liquids which was H2O, Hydrogen peroxide, salt water, sugar water, and dirty water. We observed them immediately after we put them in, after 10 minutes, after 24 hours, and after 48 hours. Our question for the experiment was "How does different liquids effect the polyacrylate?" The water made the polyacrylate bigger (645.4 px) and turned lighter colored. The Hydrogen peroxide made the polyacrylate the biggest (670 px) out of all of the other ones. The salt water only made the polyacrylate a few px bigger then the actual size (311.2 px) and it made the water pink. The sugar water made the polyacrylates kind of lumpy, they turned red, and got bigger (634.8). The dirty water made the polyacrylate the bigger (620.3 px). Our inaccuracies were some of the measurements because we couldn't fit some of the polyacralate under the microscope!
