In this activity, learners will engineer their own weather vane. This activity includes step-by-step instructions with pictures and a "What's Happening?" section explaining how the activity worked.

In this activity, learners practice counting objects found on patterned wrapping paper or fabric.

In this activity (3rd activity on the page), learners taste test different foods and categorize them as sweet, bitter, sour, or salty. Learners compare their results with the group.

In this activity, learners will build ramps and test how the laws of physics apply do different objects. Learners will explore physics and cause and effect through this activity.

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.

In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.

In this a hands-on activity, learners explore how to put ice cream in an oven without it melting. Ideas in this activity include insulation and cooking.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

This is an activity about discovering the colors and beauty of nature. Learners will spend time outdoors, matching paint chip samples, colored paper, or colors of clothing to those found in nature.

This is part 2 of the three-part "Crayon Rock Cycle" activity and must be done after part 1: Sedimentary Rocks. In this activity, learners explore how metamorphic rocks form.

In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.

In this math game, learners toss plastic cups to land just right and collect points to win.

In this math activity, learners predict how many pom-poms they can toss inside a circle from three feet away. Use this activity to help learners explore probability.

In this health activity (page 7 of the PDF), learners will discover the importance of handwashing as a factor in reducing the spread of pathogens.

In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.

In this activity (17th on the page), learners investigate why you cannot see colors in dim light.

Capture soap bubble patterns on paper! In this activity, learners can create beautiful pictures from popping soap bubbles.
