In this activity, learners will explore pi and the mathematical relationships between a circle's diameter, circumference, and radius.

In this activity, learners work in teams to simulate the process used by Global Positioning Systems (GPS) to determine the location of a fallen meteorite in Antarctica.

In this mathematics activity (page 4 of the PDF), learners will explore the relationship between the diameter and circumference of an object.

Learners use the current flowing in a wire to create a magnetic field that turns a magnet. Learners can use this property of electromagnetism to build a magnet-powered pinwheel.
