1st Grade Science Learning Activity: Evaporation

This is a great experiment to try at home. Some compounds will bound with water molecules. When you evaporate the water some compounds will form crystals.

Complete the activity online, then try a hands-on version by placing these common household items in containers. Mix with water and wait for the evaporation process to take place. Which mixtures evaporate and which do not? Did you see the same results in real life as in this online lab?
