Pupils use their imagination. They discuss the 4 C's of teamwork: Concentration, Communications, Coomperation, and Consideration. Students discuss the safety guidelines of the project. They complete a rope maze. The group walks...

Students investigate how the sun travels across the sky at different latitudes using Solar Motion Demonstrator. In this earth science lesson, students explain why seasons change. They study how the tilt of the Earth's axis affects...

Students explore how to floss their teeth properly. They observe a demonstration showing that bruising alone is not enough to remove plaque from all tooth surfaces.
