Apartment Buildings and More
Source Institutions
In this engineering activity, young learners investigate multi-level buildings.

Heavy Air
Source Institutions
In this activity and/or demonstration, learners illustrate visually and physically that air has weight. Learners balance two equally-inflated balloons hanging from string on a yard stick.

Repulsive Grape: Diamagnetism
Source Institutions
Do grapes, yes the grapes from the grocery store, move in the presence of a very strong magnet?
Double or More
Source Institutions
Choose a recipe to double (or triple, quadruple, or halve). Show everyone the recipe and engage them in figuring out: How much will we need to increase the recipe to feed everyone?

Trees: Recorders of Climate Change
Source Institutions
In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho

Oboe? Oh, Boy!
Source Institutions
In this activity, learners create a straw oboe to explore sound and pitch.

Build a Raft
Source Institutions
In this activity, learners explore density and buoyancy as they design and construct rafts.

Protect That BRAIN!: Mr. Egghead
Source Institutions
This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.

The Great Fossil Find
Source Institutions
On an imaginary fossil hunt, learners "find" (remove from envelope) paper "fossils" of some unknown creature, only a few at a time.

Loony Balloons
Source Institutions
In this activity, learners investigate how changing the center of gravity of a balloon affects how it travels. Learners fill a balloon with a little bit of water and insert into an empty balloon.

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

Lifting Lemon
Source Institutions
In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

Cylindrical Wing
Source Institutions
In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.
Signs of Change: Studying Tree Rings
Source Institutions
In this very hands-on lesson, learners will investigate dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible
Investigating Convection
Source Institutions
This experiment is designed to illustrate how fluids, including water, have the ability to flow.

Magical Match
Source Institutions
In this demonstration, learners will be "wowed" as three matches burn to form a triangular pyramid shape and "magically" rise off the table.

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

Mirror-Tracing
Source Institutions
This mirror-tracing activity related to proprioception is a visual and motor test that involves learning a new motor skill.

Release the Grease!
Source Institutions
In this simple activity (on page 7 of the PDF), learners use water and liquid dish detergent to see which one removes lipstick better from an index card.

Pinhole Magnifier
Source Institutions
In this activity related to light and perception, learners use a pinhole in an index card as a magnifying glass to help their eye focus on a nearby object.
