In this activity, learners will explore how water affects marker on filter paper. Learners will use science process skills such as making observations and predictions as they explore color.

"Exploring the Universe: Objects in Motion" encourages participants to explore the complex but predictable ways objects in the universe interact with each other.

In this math activity, learners trace their hands and estimate the number of beans that can fit into their hand tracings. Then, learners glue the beans to the tracing to test out their estimations.

This puzzle provides an interesting context which challenges learners to apply their knowledge of the properties of numbers.

In this demonstration about force and motion, learners will explore the forces that affect a pendulum A simple model pendulum comprised of a ball and string demonstrates how pendulums work as well as

In this chemistry activity (page 5 of the PDF), learners will see that chewing is more than just the crushing up of food; there is actually a chemical change going on at the same time.

In this activity (12th activity on the page), learners conduct an experiment to demonstrate how muscles are constantly feeding information to the brain about what they are doing.

In this physics activity (page 3 of the PDF), learners will see firsthand that air takes up space and has pressure by attempting to inflate a balloon inside of a bottle.

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

Take the two-straw challenge and discover how pressure affects vacuums! In this activity, learners experiment with drinking through one and two straws, comparing the amount of liquid they can drink.

“Exploring Earth: Rising Sea” is a hands-on activity demonstrating ways to use topographical mapping techniques to track changes in sea level. The activity is connected to current NASA research.

In this activity, learners will explore the foods that are in their kitchen and what sugars are inside of them. Explore nutrition and food labels to better understand the foods you eat.

In this activity, learners discover that it is difficult to trace a curve by using its reflection in a mirror. Use this activity to discuss how the brain works.

In this online Flash game, learners take to the skies in a hot air balloon and are challenged to beat other balloonists' times to the finish line without crashing.

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

In this activity, learners conduct an experiment to test how fast they can react. Learners try to catch a piece of paper with a ruler printed on it (or a ruler) as quickly as they can.

In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.

In this activity, learners mix water, cooking oil, and liquid food coloring to create beautiful colored designs in a cup. Use this activity to explore liquid density and solubility.

In this activity, learners will explore the physics of air by making a snake kite.

In this activity, learners play a game from India similar to Tic-Tac-Toe. Players take turns placing coins on the game board and sliding the coins along the spaces.
