In this activity, learners explore the relationship between electric charges and magnetic fields.

In this activity, learners map their world by drawing a plan of their bedroom.

In this activity, learners build and test a compass. Learners work in pairs and pretend they are stuck in the wilderness at night.

Learners use their opponent's clues and a compass rose to find the hidden treasure on a map. Learners use problem solving and coordinate grid skills as they hunt for treasure.

In this activity, learners use simple materials to build their own compass.

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 activity, learners make a 3-D model of magnetic fields by inserting a small, strong magnet into a sphere.

In this activity, learners explore the magnetic field of a bar magnet as an introduction to understanding Earth's magnetic field. First, learners explore and play with magnets and compasses.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.
