Whales, seals, walruses, and other marine mammals survive and thrive in very harsh, freezing cold environments. In this activity, students discover the insulation properties of several materials by testing them in a bucket of ice water; simulating how marine mammals can survive in arctic conditions, yet not freeze to death.

In this activity for primary learners, students sort animals into 2 categories: those born from an egg and those not born from an egg.
Subjects: Life Science

Students have fun using a 3D model to sort animals into 2 categories: those born from an egg and those not born from an egg.

This RAFT version of a classic game uses plastic bottles as bowling pins and a small wooden ball. It plays just like the bowling alley game, but instead of a computer keeping score, the individual players must keep track of their points. Scoring gets a bit tricky when a strike or spare is rolled, providing excellent opportunity to practice basic arithmetic.
