Learners drop a magnet through a coil of wire to create electric current in a circuit. LEDs in the circuit allow learners to detect the direction of current flow.

In this creative roleplay activity, learners will explore the various processes of the carbon cycle using movement and props to aid in comprehension.

In this activity, early learners create paintings by making music and rhythm. Learners place paper in cans, add paint-soaked beans (or pebbles) and put the tops on.

In this activity (page 2 of PDF under GPS: Cave Swallows Activity), learners will model how caves are formed by placing one piece of chalk in a cup of vinegar and another piece in a cup of water, then

In this engineering activity, young learners investigate multi-level buildings.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

Learners explore the physical properties of a variety of balls and how they bounce.

In this physics activity, learners experiment with pulleys and find that they can decrease the effort needed when using a pulley to lift or move different loads.

Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.

In this activity, learners investigate whether having sugar already dissolved in water affects the speed of dissolving and the movement of sugar and color through the water.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this "game," learners explore and relate the evolution of stars to a Navajo creation story. The story is written on a series of cards, which are laid on a table as the story is told.

In this activity about electricity, learners produce a spark that they can feel, see, and hear. Learners rub a Styrofoam plate with wool to give it an electric charge.

In this challenge, learners figure out how to make a juice stain disappear.

Learners conduct four simple experiments to demonstrate the effects of air pressure.

In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.

In this activity, learners explore light and shadows by creating a lantern they can keep on their nightstand.

In this activity, learners mix several sugar solutions to investigate the property of density. Each sugar solution has a different density and color of the rainbow.
