In this activity, learners discover a brain process called habituation.

In this activity about transfer of energy, learners get to build their own catapult using nothing more than a plastic spoon and some tape.

In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

In this activity, learners design a bungee jump for an egg using nylon stockings.

In this simple activity, learners discover how a mere piece of paper can be used to hold up the weight of a heavy book.

In this activity, learners use mirrors to write secret messages to a friend. Use this activity to explore letters, optics, and/or symmetry.

In this hands-on activity, learners determine the types of chemical reactions achieved when combining different household products.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity, learners conduct a scientific investigation involving decomposition and discover that the life cycle of trash is affected by its organic or inorganic nature.

In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.

In this activity, learners follow clues to find five puzzle pieces, then assemble them. This activity works well with a whole group, individuals, or families.

In this activity, learners are challenged, using everyday objects, to create simple machines to complete specific tasks.

In this outdoor game, learners play the roles of gray or red squirrels gathering and storing a supply of food in "fall" and recovering enough of them to survive the "winter." Learners carry bags repre

This activity puts a mathematical twist on the familiar “guessing jar.” No guesses allowed, estimates only.

Testing magnets is always a fun pastime, but here, we're going beyond "will it attract the magnet?" In this activity, learners will investigate which materials allow magnetic fields to pass through or

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

In this activity, learners look at and touch marine animal skulls to compare them and think about what they eat.

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

In this activity, challenge learners to design a roller coaster ride for a marble using cardboard and other simple materials.

In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.
