In this activity, learners sort different natural phenomena into categories (they occur on Earth, on the Moon, or on both), and then model how energy moves during a quake using spring toys.

In this activity, learners will experiment with the physics of flight by making a gliding contraption with strange looking wings. The activity explores flight with connections to the natural world.

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 quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.

Create an instrument that you don't play--you just listen to it through tubes of various lengths.

Look at pictures through different color filters and you'll see them in a new way. People have used color filters in beautiful photography or sending secret messages.

Make snack time into measuring time and learn to read Nutrition Facts labels. Try this when you’re using “pourable” foods, such as cereal, yoghurt, or juice.

In this activity, the learner asks yes-no questions to identify a secret object (similar to Twenty Questions). This game is easy to adapt for different ages and different kinds of contexts.

In this activity, learners will explore what a constellation is and make their own.

In this interactive game, learners listen to the songs of four different thrushes and then try to match each bird with its song.

This is a series of three quick science activities to do with a spoon, knife, and fork. In the first two activities, learners use the flatware to explore optics, mirrors, reflection, and distortion.

In this online activity exploring our perception of "cuteness," learners adjust various factors (like pupil size or length of limbs) on a face, a cat, and a hammer.

The Let's Do Chemistry "Build a Battery" activity lets participants learn how batteries work and how materials behave, change, and interact by building their own simple battery out of metal and felt w

“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 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 chemistry activity (on page 2 of the PDF), learners make a layered drink with liquids of different densities.

In this weather activity/demonstration, learners watch as a ping pong ball is suspended in a stream of air supplied by a hair dryer.

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 activity, learners explore materials through paper chromatography.
