Polar Cubes


Polar cubes are a great ways of bringing math, science, and social studies into your classroom.


The materials you will need for this project are found below. If the children in your classroom are old enough, have them help you make the plaster of paris mixture. Be sure to verbalize their and your actions for a unique language development opportunity.

Plaster of paris or similar product
Water, room temperature
Disposable container for mixing
Disposable spoon
Ice trays
Polar play figures


Follow the directions on your plaster of paris product. Don’t dispose any of your made up plaster of paris mixture down the sink drain. It will harden there and prevent water flow. Use disposable items in the mixing process. Poor mixture into your desire forms. I chose ice trays.


Your set time is dependent on the plaster of paris product you are using. Read the directions on back of your product conveying the wait time to your eager students. I waited 15 hours for setting with my product as indicated. Hint: You use twice as much plaster of paris as water in the mixture. You will want to purchase a large quantity of the plaster of paris for all your classroom students.


At the end of the drying time, I simply gave the ice tray an opposite handed twist and the cubes came out with ease.


Add a map of the polar regions and fun arctic toys to create an inviting science, math, and social studies experience for your children.

Learning Piece:

■  If your children are old enough, have them help you make the plaster of paris mixture. Discuss what measurements you are using. Be sure to verbalize their and your actions.

■  Identify which ingredients are a liquid or solid. Explain that unlike water, the plaster of paris can’t move from a liquid to a solid and back again.
