Using a milk-based recipe, learners create "moo glue" which is basically white school-type glue. The "secret ingredient" in milk that helps make glue is a chemical called casein.

In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

Learners analyze candy-coated sweets using chromatography. Learners use this method to separate the various dyes used to make colored candy.

In this construction activity, students use a 2-liter bottle to build a fly trap.

In this activity, learners investigate wind by comparing the force of wind in different locations. Learners build wind-o-meters out of wooden sticks and strips of paper.

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.

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.

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

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 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!

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

In this activity, learners mix up a bubbly brew and examine density. Learners explore how they can make different materials fall and rise in water using oil, water, and salt.

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 (page 3 of the PDF), learners will observe a physical change.
