Weather Preschool Lesson Plans - Rainbow Ice

This project gives kids a fun way to create colorful designs in large blocks of ice plus getting to observe how salt melts ice.
Materials: Large ice blocks (freeze water in empty one 1/2 gallon milk cartons). When the water is completely frozen, tear off the cardboard container.
Coarse salt Food coloring Eye droppers
Steps:1. Place ice blocks on trays covered with several layers of newspaper.2. Give each child some coarse salt to sprinkle on top of the ice3. Using eye droppers let the kids drip various colors of food coloring on the ice. 4. The colors drip down and create color streaks through the ice.5. If it's cold enough, put the ice blocks outside and they should stay frozen for several days.

Children love watching the changes that occur as the blocks melt away! You can bring them inside or leave them out for them to see when the weather allows outdoor playtime.
