In this activity about scale, learners investigate the world of the very small by cutting a 28 centimeter strip of paper in half as many times as they can.

This is a quick activity/demonstration that introduces learners to the concept of index of refraction. Learners place stirring rods in a jar of water and notice they can see them clearly.

In this activity, learners cook amino acids and sugar to explore the range of aromas released.

In this optics activity, learners use paint thinner to make a small jar seem to disappear inside a larger jar.

This is a quick, yet dramatic activity/demonstration that introduces learners to the concept of energy transfer. A small ball is placed on top of a large ball and both are dropped together.

In this demonstration, learners observe how liquid nitrogen both boils and freezes ingredients to make ice cream in two minutes.

In this quick activity/demonstration about density, learners examine what happens when two cans of root beer--one diet and one regular--are placed in a large container of water.

In this chemistry demonstration, learners observe a chemical reaction that produces a colorful effect.

In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.

This is a web activity about simple machines. Learners will explore a lawn mower and identify six different simple machines which work together to help make our lives easier.

In this activity, learners explore motion and airflow by setting two aluminum cans on their side and blowing air in-between them.

In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

In this activity, learners will test soil content using their sample, some water and a container that seals.

In this online activity about anatomy, learners will drag and drop pieces of the heart into their proper positions and explore what function each part of the heart has.

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

See what force a magnet has on a wire that has current running through it: will it push it, pull it, or will nothing happen? This is the foundation of a simple electric motor.

Balance a ball in the air with a hair dryer! This Exploratorium produced activity shows learners concepts like lift and air streams. You can try many different angles, speeds, and ball types.

Which one of your eyes are dominant? Do they act independently or are they equally "in control?" This activity explores how your eyes work (or don't work) together.

We're told from a young age that we have 5 senses, but we have many more. One of which is our awareness of our own body part's orientation and position.

In this quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads.
