In this activity, learners will investigate air and gravity through the use of various fabrics by through them in the air. Activity includes step-by-step instructions and extension ideas.

Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.

In this activity, learners investigate how different materials repel or absorb water. Learners use spray bottles to explore how everyday items like sponges, cardboard, feathers, etc.

In this activity, learners investigate and compare the rate of drying in different conditions.

In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.

This hands-on activity lets participant explore chemical reactions as they create a soda explosion with lots of bubbles. The bubbles in soda are made of carbon dioxide gas.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

This is an activity (located on page 3 of PDF under Hockey Sticks Activity) about composites, materials made of 2 or more different components.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

This activity (on page 2 of the PDF under SciGirls Activity: Forecasting) is a full inquiry investigation into meteorology and forecasting.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

Everybody loves boomerangs! In this activity about force and motion, the learners will experiment with boomerangs and explore how they work. This is a great activity to get learners up and moving.

In this activity, learners build a simple "rocket" with ordinary household materials to demonstrate the basic principles behind rocketry and the principle of reaction.

In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

In this activity, learners investigate wind by comparing the force of wind in different locations. Learners build wind-o-meters out of wooden sticks and strips of paper.

This activity shows you how to make amazing crystal spikes using Epsom salt and the sun.

In this activity, learners explore how polarizing sunglasses can help diminish road glare.
