Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.

In this activity, learners explore temperature changes from chemical reactions by mixing urea with water in one flask and mixing calcium chloride with water in another flask.

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.
