Animal Reflection Response
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Horse Ears), learners observe how an animal responds to its own reflection.

Sweat Spot
Source Institutions
In this activity, learners use a chemical reaction to visualize where moisture forms on the body.

Endangered!
Source Institutions
While playing a game, learners discover how the Endangered Species Act works in the United States. Learners move along a game board by answering questions correctly.

Exploring Structures: Butterfly
Source Institutions
In this activity, learners investigate how some butterfly wings get their color.

Magnetic Suction
Source Institutions
In this activity about electricity and magnetism, learners discover how a doorbell works. A coil of wire with current flowing through it forms an electromagnet that acts similar to a bar magnet.

Dissolving a Substance in Different Liquids
Source Institutions
In this activity, learners make colored sugar and add it to water, alcohol, and oil to discover some interesting differences in dissolving.

Candy Chemistry
Source Institutions
In this experiment, learners test multiple food items to see if they are an acid or base using an indicator solution created with red cabbage.

Marshmallow Constellations
Source Institutions
In this activity, learn about the cultural stories behind constellations. Then recreate your favorite constellations using marshmallows and toothpicks.

Unlocking the Secret in Product Codes
Source Institutions
In this activity, learners will explore how product barcodes are scanned accurately and be able to "guess" the last number in a 13 digit barcode correctly every time.

Dancing Cereal
Source Institutions
In this quick activity (on page 2 of the PDF under GPS: Body Electricity Activity), learners will observe how dry breakfast cereal appears to dance when it gets close to a balloon charged with static

Ancient Sun Observations
Source Institutions
In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.

Turbidity
Source Institutions
This is an activity about turbidity, or the amount of sediment suspended in water.

Vocal Visualizer
Source Institutions
With a bit of PVC, a laser, a can/cup, and a small mirror, you can make a device that visualizes you voice or any sound transmitted into the cup/can.

Size it Up
Source Institutions
Learners investigate why the Sun and Moon appear the same size in the sky even though the Sun is over 400 times larger in diameter.

Exploring Ultraviolet (UV) light from the Sun
Source Institutions
In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

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.

Life in the Sidewalk Cracks
Source Institutions
In this activity, learners compare plant and animal life in different habitats including a sidewalk crack and lawn. Learners sort human-made materials and natural materials found in each habitat.

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

Build a Better Roof
Source Institutions
In this activity, learners will engineer a roof using simple materials to protect a construction paper person from a rainstorm.

Turning the Air Upside Down: Convection Current Model
Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.
