Polyacrylate Conclusion:
We tested the diameter of the polyacrylate crystals while they were in dirty water, tap water, hydrogen peroxide, salt water and sugar water. Over the course of immediately, 10 minutes, 24 hrs and 48 hrs. Our question was 'which liquid makes the polyacrylate crystals grow the largest?' After each time interval the hydrogen peroxide caused the orbees (polyacrylate crystals) to grow the biggest! After 24 hrs. the orbees were 653 px in diameter in the hydrogen peroxide. While the closest orbees in diameter in any other liquid totaled 635 px (dirty water). Sometimes when we measured the orbees that were in hydrogen peroxide it wouldn't fit in the petridish for the microscope so the measurements may be a few pixels off. We observed that some of the orbees changed color because of the liquid they were in. For example, the hydrogen peroxide caused the orbees to turn clear, the sugar water made them turn red. I understand now that hydrogen peroxide cause the orbees to grow the most! I wonder what it is IN the hydrogen peroxide that makes them grow.. Mayb e the oxygen? Who knows? Maybe I'll conduct another experiment to find out! I'll keep ya updated!!!!
