Single Replacement Micro-Reactions
Source Institutions
In this chemistry activity, learners use common chemicals and metals to explore single replacement reactions.

Hot Stuff!: Investigation #3
Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.

Do Sweat It!
Source Institutions
In this activity, learners explore why humans sweat. Learners compare the effects of heat on a balloon filled with air and a balloon filled water.

Challenge: Microgravity
Source Institutions
In this activity about the circulatory system and space travel (on page 38 of the PDF), learners use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the bod

Build a Band
Source Institutions
In this design challenge activity, learners build a four-stringed instrument that can play a tune.

Stomp Rocket
Source Institutions
In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.

Forward-Reverse Switch
Source Institutions
In this activity, learners build a switch to turn electrical circuits on and off.

Woodpecker
Source Institutions
In this activity, learners construct a traditional handicraft toy that illustrates a motion commonly associated with violins and earthquakes.

Delicious Smelling Chemistry
Source Institutions
In this activity, learners use household materials to investigate and explore their ability to smell an odor.

Changing Colors
Source Institutions
In this activity, learners will explore how different colors of lights interact with objects around them. Will a blue object stay blue with a red filter?

Make a Speaker
Source Institutions
In this activity, learners explore how an electromagnet works by making a simple one. Using this knowledge, learners design a diagram to make a working speaker using household materials.

I Spy Nano!
Source Institutions
In this game, learners try to find nano-related objects on a game board. Learners investigate the different ways nano is in the world around us.

Sand Castle Saturation
Source Institutions
In this activity about saturation (page 1 of PDF under SciGirls Activity: Sand Dunes), learners will build a series of sand castle towers using a 16 oz cup.

Como funciona un extintor
Source Institutions
In this Spanish-language chemistry activity, learners use simple materials to explore how fire extinguishers work to put out fires.

Anti-Bubbles
Source Institutions
In this activity, learners will be making the opposite of a bubble, an anti bubble! This low start up activity is fun, informative, and best of all-a little messy!

Colors in Nature
Source Institutions
In this activity, learners create colorful bead bracelets to wear outside while searching for matching colors in plants. Learners will be surprised by the variety of colors in nature.

Soda Geyser
Source Institutions
In this quick activity (page 1 of PDF under SciGirls Activity: Lift Off), learners will use the ever-popular soda geyser experiment to test the reactivity of the various sugar candies or mints.

Monitoring Amphibians
Source Institutions
In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

Grow Rock Candy
Source Institutions
Learners grow sugar crystals (rock candy). They make a hot solution that has an excess of sugar dissolved in it, then as the solution cools, they see sugar crystals form.

Show Your Colors!
Source Institutions
In this family or group activity, learners conduct a chromatography experiment to reveal the colors that leaves "hide" under their green pigments.
