LAB TASK #1

You have four powders: baking soda, cornstarch, powdered sugar, and plaster of paris. Your job is to figure out which one is which. You must make careful observations of each powder to try to determine its identity.

You may observe them in any of the following ways:

• What do they look like? (Try using a magnifying glass.)
• What do they feel like? (Pinch some between your fingers.)
• What do they smell like? (Be careful not to inhale them up your nose.)
• DO NOT TASTE THEM!
