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

In this activity (11th activity on the page), learners use pennies to test their hearing acuity.

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.

In this quick activity/demonstration (5th on the page), learners explore depth perception.

In this health activity, learners create a device so that they not only feel their heartbeat, but also see it, using a straw and some clay.

In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

In this activity, learners make an optical illusion toy from the 1800s to explore persistence of vision.

In this activity, learners investigate static electricity using everyday objects at four different stations.

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

Build a fruit fly trap out of a 2-liter plastic bottle and some rotten fruit! Fruit flies are easy to catch in warm weather. Once you catch some, you will be able to see their life cycle up-close.

In this online activity, learners experience the thrill of pickle making, and explore how a cucumber becomes a pickle.

Choose a recipe to double (or triple, quadruple, or halve). Show everyone the recipe and engage them in figuring out: How much will we need to increase the recipe to feed everyone?

In this activity, learners will explore saturated solutions and discover how crystals form.

In this quick activity, learners observe how wind creates ocean currents.

In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.

In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.

In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

In this math activity, learners guess which cereals contain the most sugar. Learners use the nutrition labels on the cereal boxes to find the cereal with the least amount of sugar.
