Why is the Sky Blue?
Source Institutions
In this activity, learners create a "mini sky" in a glass of water in a dark room.

Gravity and Falling
Source Institutions
This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.

Human Impact on Estuaries: A Terrible Spill in Grand Bay
Source Institutions
In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

Powder Particulars
Source Institutions
In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.

Metal Noise Maker
Source Institutions
In this activity, learners explore how sound travels through solid objects better than through air. Leaners attach a metal clothes hanger to a piece of string and hold it to their ears.

Electrostatic Water Attraction
Source Institutions
In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.

Suminagashi: Floating Ink Paper Marbling
Source Institutions
In this activity, learners try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.

Airboat
Source Institutions
In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

Fly a Hot-Air Balloon
Source Institutions
Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

How Do We Find Planets Around Other Stars?
Source Institutions
This fun and simple hands-on astronomy activity describes techniques scientists use to find planets orbiting other stars.

How Small Can You Cut?
Source Institutions
In this lesson, learners cut paper into very small pieces to explore the small size of quarks, the smallest thing we know of on Earth.

Postcards from Space
Source Institutions
Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the

Playground Patterns of Cracks
Source Institutions
In this math activity, learners observe and sketch cracking patterns in pavement.

Polarized Sunglasses
Source Institutions
In this activity, learners explore how polarizing sunglasses can help diminish road glare.

Whale Cart
Source Institutions
In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).

Cake by Conduction
Source Institutions
In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

Zoomers
Source Institutions
In this activity, learners build their own rockets from paper, coffee stirrers, and tape. Learners discover that when anything flies, air pressure is always involved.

Does Your Chewing Gum Lose Its Flavor?
Source Institutions
Each learner chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days.

Writing for Night Vision
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Forensics), learners will use a home video camera with a “night vision” mode to test how various inks appear outside the spectrum of visibl

Ramps 2: Ramp Builder
Source Institutions
In this inquiry-based learning activity, learners design, build, and test their own ramps. They are introduced to a variety of materials and explore putting them together.
