Summer Activity- Ice Block full of toys
A great idea for a hot summer day! Take a large plastic bowl and fill with small toys and water. Let freeze overnight and dump out the block of ice on your driveway or porch. You can let those little curious fingers chisel the ice with their plastic tools to search for their treasures. Another idea would be to let the children poor water over the ice to see the ice become smooth and glossy.

Iridescence
An opitcal phenomenon! The color of the surface changes if it is viewed at a different angle. Try this fun ice cube experiment.
Materials: Ice cubes, salt, food coloring (including RED), bowl
Pour ice cubes into large bowl and then sprinkle salt over the cubes. Add one color of food coloring at a time and see if you see the shimmer? Iridescent color! Some great links below for information on what is happening during experiment.
