Next add blue hot water (dye with blue food coloring) The hot blue water will rise to the top of the pitcher

Magnified Shells and Sand
Submitted by Lori
Place several shells and sand along with a magnifying glass in an area of your classroom. Your children will love getting to see the patterns and makeup of these items.
Salt and Freshwater Animals
Submitted by Ginger
Make a salt water solution and dye it with food coloring. Fill the jar half full of salt solution and then slowly pour plain tap water on top of the solution. The salt water will stay at the bottom of the solution because it is heavier. Release a couple of small brine shrimp (check a pet store) and a goldfish into the solution. The shrimp will go to the seawater bottom while the goldfish will stay at the top (freshwater).
