Flame Test Lab: Q # 4

This lab was a lot of fun to do. I learned that certain metal salts make a certain color flame when ignited. This can be useful when unknown chemicals are found and its necessary to know what kind they are. By igniting them, you can find out what they are by just knowing what color the chemical emits. If you can find a match then you can know if the chemical is harmful or not. This is important to know so the chemical doesn't contaminate a water supply. I found that some have to be viewed under a Co glass in order to see the correct flame. This is important because a substance could be viewed incorrectly if not using the correct identifiers. Overall this was a good and fun lab to do.

1. How do scientists measure quantities?
Scientists measure quantities by using The Metric System or The English System.
2. How can error or uncertainty in measurements be
    estimated?
Error or uncertainty can be measured by first recording the digits that you know. You always have one estimated number in each measurement you make making all your measurements uncertain and estimated in some sort.
