Week 15
This week in lab we tested an experiment and acted as if we were presenting the same lab to a class of fifth graders. The experiment we conducted was using baking soda and vinegar to prove the conservation of matter theory is valid. We ran into issues that there was weight being lost. When we weighed everything seperately and then combined the weights and then combined the substances and added a balloon to the top of the bottle. The weight that totalled up was drastically different than the post reaction weight. We adjusted our experiment and put the bottle with viengar on the scale and added a ballon filled with baking soda to the top of the bottle. Once we got the weight from this, we dropped the baking soda into the bottle. Our assumption was that this weight would be the same but it still lost weight. Our final adjustment was adding baking soda into a test tube, dropping it into the bottle without it touchign the vinegar in the bottle, putting the cap on the bottle, and check...
