In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

In this activity, learners explore how wind energy can be generated on both a large and small scale.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

In this activity, learners explore the function and engineering of dams and how dams have many uses and solve many problems in the world.

In this activity, learners explore how engineers work to solve the challenges of a society, such as efficient planting and harvesting.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

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

In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

This activity (located on page 3 of the PDF under GPS: Lava Flow Activity) is a full inquiry investigation into the relationship between an object’s mass and the distance it is thrown by a catapult.

In this activity, learners will determine if the frequency and intensity of hurricanes are changing using real data from the National Hurricane Center.

In this activity, learners explore how watermills have helped harness energy from water through the ages.

In this activity, learners use tsunami time travel maps to predict how long it will take a tsunami to reach the shore.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

In this activity, learners explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.
