Mystery Powder
By : Jonathan

My classmates and I worked hard to find out what the mystery powder was.  This is what it was: baking soda,  salt, corn starch.  How I know the difference between salt  and  sugar: First we looked at sugar and salt under a hand  lens.  You see that salt has little crystals.  Sugar looks like little transparent balls.  How we know the difference baking soda and calcium carbonate:  When we put PR PT in baking soda, it turns pink.  How do we know the difference between citric acid corn starch:  It turns black oily cream .                   

Some of the other test were with iodine, PR, PT, vinegar, alcohol, water and oil.  We tested with some other powers.  These are the powers:  citric acid, salt, baking soda, corn starch, calcium and sugar.  We tested  the liquids and  powder  to figure out what was the mystery powder.

This is how I think it happened:  It was a dark night.  Everyone was asleep.  A truck came to deliver powders to Best Buy Bakery .  The guy was driving slowly into Best Buy, when he fell asleep for a few seconds.  He crashed into the school yard street.  The bags of powders flew from the truck.  The bags were intact.  The guy woke up and saw the bags the powder.  Some of the powders leaked out of the bags. The driver knew that he would get fired if his boss found out about the accident, so he left it and went to the bakery to deliver the remaining bags that had powder .
