It's a Gas!
Source Institutions
In this simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.
Message in a Neuron
Source Institutions
In this activity, learners play a simple card game to learn the sequence of events in the transmission of nervous system signals.
Marble Game
Source Institutions
In this activity, learners construct a simple game to test their hand-eye coordination and steadiness of hand.
Mirrors and Images
Source Institutions
In this optics activity, learners explore how many objects they can see in a set of mirrors (hinged like a book) at various angles.
Divers
Source Institutions
Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.
Scream Cup
Source Institutions
In this activity, the learner will experiment with the physics of sound production while making a sound making toy. The activity includes a video with step by step instructions.
CD Spectroscope
Source Institutions
In this activity, learners use an old CD to construct a spectroscope, a device that separates light into its component colors.
Why Circulate?
Source Institutions
In this activity related to the human circulatory system (on page 10 of the PDF), learners observe the dispersion of a drop of food coloring in water, draw conclusions about the movement of dissolved
Drugs, Risks and the Nervous System
Source Institutions
In this activity, learners estimate risks associated with different events and compare their estimates to the real possibilities.
How Far?
To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.
Cartesian Diver
Source Institutions
In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.
Perching Parrot
Learners explore the concepts of equilibrium and center of mass by seeing how non-symmetrical objects balance.
Pinhole Viewer
Source Institutions
In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.
Hovercraft Racers!
Learners build a simple hovercraft using air from a balloon to levitate a craft made from a compact disc (CD).
Carbon Sequestration
Source Institutions
In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra
Free Fall
Source Institutions
In this quick activity (page 1 of PDF under SciGirls Activity: Hockey), learners will use a simple physics of motion and gravity demonstration to test their predicting skills.
Earth's Energy Cycle: Albedo
Source Institutions
In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.
Blind Spot
Source Institutions
In this activity, learners conduct a simple test to find their blind spot.
Screaming Balloon
Source Institutions
In this quick activity (page 1 of the PDF under SciGirls Activity: Extreme Sounds) about sound vibrations, learners will investigate which small objects, such as coins, hex nuts, or marbles, produce t
Shadow Dance
Source Institutions
In this activity, learners experiment with shadows and light sources to understand the relationship between the angle illumination and the shadow's length.
