Vanishing Rods
Source Institutions
This is a quick activity/demonstration that introduces learners to the concept of index of refraction. Learners place stirring rods in a jar of water and notice they can see them clearly.

Musical Sculpting Machine: Squeeze Play-Doh to Make Music
Source Institutions
Play-Doh is conductive! Use the semiconductive qualities of Play-Doh to make your own squeezable instrument. Pico Cricket is required.

Catapult
Source Institutions
Build a catapult that transforms the potential energy of a twisted rubber band into kinetic energy. Experiment with design variations so that you can hit a target with a projectile.

Build a Bubble Circuit
Source Institutions
In this engineering design challenge, learners make a bubble maze that allows bubbles to move through a series of “on” and “off” switches.

Glow in the Dark Jello
Source Institutions
In this activity, learners will make homemade jello that glows under a blacklight. They will learn about quinine, an ingredient in tonic water that is fluorescent.

Measuring Biodiversity
Source Institutions
Learners use a variety of beans to represent a variety of species, and scatter these beans over a large piece of paper representing the environment.

Assembly Line
Source Institutions
In this activity, learners work individually to assemble a product and then work in teams to design, construct, test, and redesign an assembly line process whose product must meet specific quality con

Soap-Film Interference Model: Get on our wavelength!
Source Institutions
By making models of light waves with paper, learners can understand why different colors appear in bubbles.

Build a Big Wheel
Source Institutions
In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

Can I Get Some Pi?
Source Institutions
In this activity, learners will explore pi and the mathematical relationships between a circle's diameter, circumference, and radius.

Power To Go
Source Institutions
Learners observe an electrochemical cell constructed from a small jar containing zinc and copper strips immersed in separate solutions. The strips are connected to a motor that turns a small fan.

My Solar System
Source Institutions
In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.

Shaving Cream Marbling
Source Institutions
In this activity, learners will create beautiful greeting cards by marbling with shaving cream and food dye. They will explore the chemistry behind the art of marbling.

Having a Gas with Cola
Source Institutions
In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

Fruit Xylophone: Fruit Salad Instrument of the Future!
Source Institutions
This is a perfect summertime lunch activity! Pico Cricket is required (micro controller). First, get a bunch of cut up fruit, line them up, then plug a piece of fruit with a Pico Cricket sensor clip.

Engineer an Octopus Suction Pad
Source Institutions
In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

Envirolopes
Source Institutions
In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.

Yeast Balloons: Can biochemistry blow up a balloon?
Source Institutions
Using yeast, sugar, and water, learners create a chemical reaction which produces carbon dioxide (CO2) gas inside a 2-liter bottle. They use this gas to inflate a balloon.

Newton's Cradle
Source Institutions
Build your own version of the classic physics toy using simple materials.

Sail Away
Source Institutions
In this activity, learners explore watercraft engineering and sailing.
