Investigating Convection
Source Institutions
This experiment is designed to illustrate how fluids, including water, have the ability to flow.

Pop Rockets
Source Institutions
In this activity, learners make film canister rocket ships. A fin pattern is glued onto the outside of the canister, and fuel (water and half an antacid tablet) is mixed inside the canister.

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.

Jumping Beans
Source Institutions
In this physics activity (page 3 of the PDF), learners will explore the concept of static electricity.

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

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.

The Thousand-Yard Model
Source Institutions
This is a classic exercise for visualizing the scale of the Solar System.

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.

Tiny Pants Photo Challenge
Source Institutions
In this activity, learners use a simple trick of perspective to dress friends in tiny cutout clothing. Learners make tiny pants out of card stock and tape them to the end of a stick.
Growing Rock Candy
Source Institutions
In this activity, learners make their own rock candy. Crystals will grow from a piece of string hanging in a cup of sugar water. The edible crystals may take up to a week to form.

Finding the Sweet Spot
Source Institutions
In this activity, learners will discover how to find the "sweet spots" on a baseball bat. Whenever an object is struck, it vibrates in response.
Floating Paperclip and Other Surface Tension Experiments
Source Institutions
In this activity, learners experiment with surface tension using everyday household items such as strawberry baskets, paperclips, liquid dish soap, and pepper.

Fog Chamber
Source Institutions
In this weather-related activity, learners make a portable cloud in a bottle.

Volcano Baseball
Source Institutions
In this game, learners are volcanoes that must complete several steps to erupt. Starting at home plate, learners draw cards until they have enough points to move to first base.

Building a 3-D Space Maze: Escher Staircase
Source Institutions
In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

Magnetic Free Fall
Source Institutions
In this activity, learners use a pencil, magnets, and mat board to illustrate Newton's Second Law.

Copter Engineering
Source Institutions
In this activity, learners engineer a paper helicopter that spins to the ground when dropped.

Rainbow Refraction
Source Institutions
In this activity, learners will explore how light can refract or break apart into different colors.

Geyser
Source Institutions
This Exploratorium activity can be used in many contexts because geysers are great opportunities for learning about heat and temperature changes as well as geological/space science phenomena.

Your Blind Spot
Source Institutions
In this activity, learners will explore how their own eyes work by experimenting with their photoreceptors.
