In this activity, learners explore how salt water freezes in comparison to fresh water.

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this activity, learners explore how pens have been engineered and re-engineered over time. Learners work as a team to develop a working pen out of everyday items.

In this activity (pages 17-31), learners are introduced to techniques that are used to determine the structures of solid materials.

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 engineering design challenge, learners make a bubble maze that allows bubbles to move through a series of “on” and “off” switches.

In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

In this engineering design challenge, learners build an air-powered spinning machine.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

In this experiment using sprigs of Elodea, learners will observe a natural process that removes carbon dioxide (CO2) from Earth's atmosphere.

In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.

This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity, learners explore rocketry and the principals of space flight.

In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

Learners will understand the relationship between climate change and sea-level rise.

In this activity, learners explore the devices used over time to measure changes in temperature.

In this activity, learners will explore the water cycle by creating a small atmosphere.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.
