In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

In this activity, learners investigate and compare the rate of drying in different conditions.

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

In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

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 evaluate the potential performance of air rockets placed inside a wind tunnel.

In this activity, learners investigate wind by comparing the force of wind in different locations. Learners build wind-o-meters out of wooden sticks and strips of paper.

In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.

In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

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.

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