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.
The Straw Flute
Source Institutions
In this is activity about sound and vibration, learners create their own 'flutes' with drinking straws, then investigate how changing the length of the straw affects the sounds that are produced.
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.
Floating Paper Clip
Source Institutions
In this activity, challenge learners to float a paper clip in a cup of water. Learners discover that a paper clip will sink in a cup of water, except when it is placed on a piece of paper towel.
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.
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
Polynomial and Rational Functions: Building Boxes
Source Institutions
In this math lesson, learners explore polynomial and rational function patterns.
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.
Straw Kazoo
Source Institutions
In this activity, learners make some music by constructing a kazoo out of a simple plastic drinking straw. Use this activity to explore sound, vibrations, and music.
Why Doesn’t the Ocean Freeze?
Source Institutions
In this activity, learners explore how salt water freezes in comparison to fresh water.
The Three Little Pigments: Science activity that demonstrates the primary and secondary colors of lightScience activity that demonstrates the primary and secondary colors of light The Three Little Pigments Know your C, M, Y, and K.
Source Institutions
Align four color transparencies, each one a single color (cyan, magenta, yellow, and black), and see a beautiful full color image.
The Ripple Tank
Source Institutions
In this optics activity, learners create a ripple tank from household materials to study waves. Learners build the tank and then explore by making various types of waves.
Graph Dance
Source Institutions
In this activity, learners "dance" (move back and forth at varying speeds) by reading a graph. This is a kinesthetic way to help learners interpret and understand how motion is graphed.
Jem's Pykrete Challenge
Source Institutions
In this activity, learners make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.
