The team noticed these were chemical reactions because in the vinegar test, formation of bubbles happened if CO2 was present, the heat test had an odor change and a temperature change, and finally, the iodine test changed color if starch was present. 6.) After coming up with our hypothesis, our team had to test and retest it because we had to make sure that it was positively the right person. Testing our hypothesis multiple times will better the chance have having the right person or we would be putting an innocent person in jail. 7.) During the lab, we had to take many precautions on making sure we didn’t cross contaminate. When we were testing the substances in the testing tablets, after doing all the tests for one ingredient, we had to thoroughly wash the tube out so we could put the next ingredient in. Another was that only one ingredient container was allowed to be open during testing. also, one ingredient container was allowed to be open on the testing table. 8.) Next time another mystery comes up on our forensic team, I think we need to assign jobs on what to do so it isn’t jumbled up and thinks can move smoothly and
