Water Sampling
What is the best way to test water quality? Using plastic bottles, scholars create monitoring sensors to test water quality. Creating three different sensors allows individuals to measure water quality at different water levels.
Curated OER
Boat Design
Learners build a boat and make predictions. In this geometry instructional activity, students design a cargo boat. They must show that the boat they designed can carry the cargo.
Curated OER
Fishy Physics
Students explore how fish are able to move easily from one depth to another in water. In this fish lesson students create their own balloon fish.

Who Sunk the Titanic
Students discuss possible reasons for the Titanic sinking. They are split into small groups to research a historical figure involved in the sinking of the Titanic. They formulate a way to prove their characters guilt or innocence....
Curated OER
How Dense Are You?
Young scholars examine how density is a value that describes what type of a material an object is made of regardless of its shape or size.
