In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

In this activity, learners mimic remote sensing. Learners use a stick to measure the distance to a "planet surface" they cannot see, and create their own map of the landscape.

In this activity about saturation (page 1 of PDF under SciGirls Activity: Sand Dunes), learners will build a series of sand castle towers using a 16 oz cup.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.

In this activity, learners are introduced to challenges of maintaining temperatures while living in space.
