In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.

In this chemistry activity, learners explore density by using four solids and 6 liquids to create colorful, layered rows.

In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

This lesson gives full instructions for making cabbage juice indicator, a procedure sheet for learners to record observations as they use the indicator to test materials, and extension activities to d

In this activity on page 11 of the PDF, learners follow simple steps to recycle old newspaper into new paper.

Learners design their own experiment to determine which M&M color dissolves the fastest in water.

Is this activity concentrating on physical science, learners build their very own miniature hovercraft out of a paper cup. Using it, they can explore the concepts of friction and force.

In this meteorological activity, learners get to build their very own anemometer (instrument for measuring wind speed) using a paper cup.

In this activity, learners explore how their depth perception would be affected if they only had one eye. Learners work in pairs and attempt to drop a penny in a cup with one eye covered.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this activity, learners test what happens when they put baking power on different frozen liquids.

In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

This is an activity about rockets. Learners will explore how rockets leave Earth's orbit and what it takes to make a launch successful.

In this hands-on experiment, kids use chemistry to explore whether acids or bases are better at restoring a penny’s shine.

In this activity, learners see how many coins they can add to a full glass of water before the water overflows.

In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.

In this activity about center of gravity (page 23 of PDF), learners investigate how the body adjusts to the force of gravity to remain balanced.

In this activity, learners make acid/base indicator paper, place the indicator paper on an anthill, disturb a bunch of ants, and then observe what happens!
