In this activity, learners explore the concepts of density and basic chemical reactions as they create a homemade lava lamp effect using water, oil, food coloring, and Alka-Seltzer tablets.

In this activity related to magnetism and electricity, learners observe as two parallel, current-carrying wires exert forces on each other.

In this outdoor game, learners role play populations linked in a food chain.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

In this hands-on activity, learners make the world's simplest Cartesian diver, using only a plastic bottle, some water, and a condiment packet.

In this activity, learners will turn an ordinary tray of sand into a desk-top garden for meditation.

In this design challenge activity, learners use tubes of newspaper to make a table that’s at least eight inches tall and strong enough to hold a heavy book!

In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.

Learners make their own simple slide rules out of paper and learn how they work.

This activity (8th activity on the page) tests learners' ability to identify things using only the sense of hearing.

In this outdoor activity, learners find out the color of food that jays prefer and then try to change the birds' preference by altering the taste of the food with salt.

This activity is designed to let learners measure their reaction time or response time to something they see.

This is an activity (located on page 3 of PDF under Gecko Feet Activity) about modeling a nanoscale phenomenon (gravity-defying gecko feet) with macroscale objects (shoes).

This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.

In this activity (3rd on the page), learners conduct a series of tests to find out which of their eyes is more dominant.

This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.

In this activity, learners make a Benham Top to explore visual illusions and optics.

Learners investigate an iron-fortified cereal by stirring it with a strong magnet. They discover that metallic iron is present in some cereals.

In this activity, learners construct drawing machines using a cup, some markers, and a battery pack. The markers act as "legs" for the machine, making a drawing that records as it moves.

In this neuroscience activity (5th activity on the page), learners explore their sense of touch without using their senses of vision and hearing.
