Sensory Detectives
Test your learners' sensory awareness with three hands-on activities that ask pupils to use their other senses to identify and describe everyday objects hidden from sight.
Beyond Benign
Packed Up Properties
Determine physical properties of potential packaging materials. Continuing from previous lessons in the series, the resource asks groups to identify physical properties of the substances. They test for conductivity, solubility, water...

Why Do Raindrops Sometimes Land Gently and Sometimes with a Splat?
A mouse can fall from large heights without injury! Air resistance is a large influence on small falling objects. In an exploratory lesson, young scholars build a raindrop bottle to compare the falling rate of different-sized objects.
