Dr. Stench's Iodorizing Foot Dust
Evidence Report The evidence contains ingredients B and E because when testing ingredient B during the heat test it burnt like the evidence. The evidence is like E because during the visual examination test I noticed they were both chunky, white powders. Also B and E are like evidence because during the Iodine test it didn't turn purple or blackish so there was no starch, and Evidence is like E because there was bubbles during the vinegar test. That’s why I know that Miss Tavaglione’s Dr. Stench’s Deodorizing Foot Dust was the evidence and the mysterious powder at the scene. That’s how I know Miss Tavaglione took the gradebook. The Most useful powder test I used was the heat test because E, B, and evidence all had similar reactions during

The iodine test was a change in color when we were testing for starch. It is important to retest by making your own of the ingredients because you need to know what ingredients it is you can’t just say it’s B and E because that's not good evidence and the only way to test evidence again to have clues on what the powder is you have to mix different ingredients. To avoid cross contamination we put in little bits of each ingredients in not all at once. This is so that it doesn’t accidentally tip of the spoon into another ingredient. To improve the lab I would give everyone a spot plate and each of them do their own ingredient and we share the different substances. This is so we take less time setting the spot plate up. If to suspects use the same foot powder I would measure the foot size of the footprint and determine who has the bigger foot. The police department or fire department would use chemistry to determine maybe a burnt house. What if a house caught on fire and it was because of a lightbulb and they didn’t know which light bulb it was. By leaving each different light bulb on and seeing which one gets the hottest you can determine which light bulb it was so you can put it on the report of the burning
