In this activity, learners model erosion using a clear shoebox and sand or soil.

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.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.

In this activity, learners design and build their own parachute using household materials with the goal of landing their passenger safely on a target.

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