In this activity, learners will use Google Sky to observe features of the night sky and share their observations.

In this water activity, learners discover ways to move water across the water table.

This is an activity about waves. Using marbles, paper clips and rubber bands, learners explore how waves behave.

In this activity about archaeology, learners will explore different Egyptian hieroglyphs and recognize their meanings and uses.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this activity, learners construct a simple air pressure launcher for paper rockets.

In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.

In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

In this activity, learners imagine what the world might look like if we could build an elevator to space!

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

In this activity, learners use maps to locate the Arctic region and use a word game to discover the types of resource people need to survive in the extreme climate.
