Learners take on the role of environmental engineers as they design water filters.

Learners gain an intuitive knowledge of the physical aspects of watersheds by creating their own watershed models.

In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the
