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.

Ready, Set, Fizz!
Source Institutions
In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

Rainbow Film
Source Institutions
In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

Beachcombing
Source Institutions
In this outdoor activity, learners become beachcombers as they walk on a sandy beach in search of evidence of life.

Egg Drop Trick
Source Institutions
In this activity, learners explore the real science behind an egg drop "magic trick." Learners will wow their families by harnessing gravity, friction and motion to make 3 eggs fall off of their pedes

Honeycomb Geometry
Source Institutions
In this activity, learners will build a honeycomb. Learners will investigate how the shape of the honeycomb develops. Activity includes step-by-step instructions and extension ideas.

Disappearing Colors
Source Institutions
In this challenge, learners figure out how to make a juice stain disappear.

Bonseki Salt Art
Source Institutions
In this activity learners will be creating art using a traditional Japanese art style.

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.

Fingerprint Identification
Source Institutions
In this activity (on page 2) about fingerprint analysis, learners use graphite from a pencil and scotch tape to capture their fingerprints.

Gluep
Source Institutions
In this chemistry activity, learners make a slimy non-Newtonian fluid called "Gluep." Use this activity to introduce learners to polymers and viscosity.

Olympic Track Meet
Source Institutions
In this activity, learners discover how exercise helps keep the body healthy. Learners increase their heart rates by running and understand how running fast versus walking affects their pulse rates.

Moonlight Serenade
Source Institutions
In this activity, learners act as the Earth and observe how different angles between the Sun, Earth, and Moon affect the phases of the moon we see each month.

Your Father's Nose
Source Institutions
In this fun optics activity, learners explore principles of light, reflection (mirrors), and perception. Learners work in pairs and sit on opposite sides of a "two-way" mirror.
Hot and Cold: Endothermic and Exothermic Reactions
Source Institutions
Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.

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.

Line Up: Using Math To Stand In Line
Source Institutions
Put math of measurement into lining up — and make waiting in line fun. Choose a size characteristic that learners can physically compare, such as foot length or hair length.

Toilet Paper Solar System
Source Institutions
In this activity, learners build a scale model of the solar system using a roll of toilet paper.

Watch and Create! Creativity For Sustainability
Source Institutions
In this activity, children and adults work together to explore their relationship with technology and examine ways to make sustainable media consumption choices.

Mini Zoetrope
Source Institutions
In this activity (posted on March 27, 2011), learners follow the steps to construct a mini zoetrope, a device that produces an illusion of action from a rapid succession of static pictures.
