In this activity, learners use simple materials to build their own compass.

In this activity, learners work in teams to simulate the process used by Global Positioning Systems (GPS) to determine the location of a fallen meteorite in Antarctica.

In this activity, learners explore how engineers work in a team to solve problems.

In this activity about potential and kinetic energy, learners get to roll a can across the floor and then watch it roll back to them as if by magic. This activity is always great for looks of wonder!

In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.

In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

In this design challenge activity, learners build a device to carry a Ping-Pong ball from the top of a zip line to the bottom in four seconds (or less!).

This lesson plan provides learners with two activities to explore the connections between events in their lives and the seasons of the year.

In this activity about olfaction (8th activity on the page), learners smell 10 different items with different odors. Then they try to identify the smells when they are mixed together.

In this activity, learners observe a quick phase change as water rapidly goes from a liquid state to a solid state.

In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.

In this activity (1st activity on the page), learners explore their sense of taste and the structure of the tongue by taste-testing various foods.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.

In this outdoor activity, learners discover how the environment around a building affects the growth of plants.

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

In this activity, learners explore how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count.

This activity (on pages 10-12 of the PDF) encourages learners to consider what makes living things different from non-living things.

In this experiment, learners isolate Deoxyribonucleic Acid (DNA) from onion cells using a simple extraction procedure.

The demonstration/experiment provides quick proof that air has mass.
