Experiment - Mystery Powders

Simple Mystery Powder

Step #1 - Feel of each mystery powder.

Simple Mystery Powder

Step #2 - Determine how the mystery powder reacts to heat.

Does it burn, melt, bubble, smoke, caramelize, turn color, or have no reaction at all?

Simple Mystery Powder

Step #3 - Determine how the mystery powder reacts to iodine.

Does it turn yellow, brown, red, black, purple or multi-colored?

Simple Mystery Powder

Step #4 - Determine how the mystery powder reacts to vinegar.

Does it fizz, foam, bubble, make noise, harden, dissolve, etc.?

Based on the data gathered can you identify which of the white powders were sugar, salt, flour, baking soda, corn starch, and plaster of Paris.
