Build a Rocket - and a Launch Pad!
Source Institutions
In this activity, learners construct a rocket powered by the pressure generated from an effervescing antacid tablet reacting with water, and build a launch pad for their rocket.

Dinosaur Dig
Source Institutions
This is an activity about dinosaurs, fossils, and the work of paleontologists. Learners use hand tools (paint brushes, scoops, and sifters) to unearth fossil specimens in tubs of birdseed.

Over the Hill
Source Institutions
In this physics activity, learners construct a small-scale version of a classic carnival game.

Corner Reflector
Source Institutions
In this optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.

Family Flyers
Source Institutions
In this activity, learners work in teams to build and test paper airplanes. Learners try to fly their airplanes directly on the runway and earn points for accuracy.

Floating Head Cup
Source Institutions
In this activity, learners watch a figure "magically" float up through the air.

Fossil Rocks
Source Institutions
In this activity, learners will discover how fossils are dug out of the earth by carefully exposing treasures hidden in an artificial rock that is easily made at home.

Whatta Web
Source Institutions
In this activity, learners play a game to simulate the food chain.

A Balancing Act
Source Institutions
In this plant science activity, learners role play as vegetables and weeds competing for nutrients.

Metal Heads
Source Institutions
Pairs of learners play the roles of programmer and robot. The programmer gives specific directions to the robot to accomplish a simple task (e.g. walk across the room and pick up a pencil).

Balancing Act
Source Institutions
In this physics activity (page 6 of the PDF), learners will build a class 1 lever and hypothesize and test the distances two objects need to be placed from the fulcrum in order to balance.

Stack 'Em Up
Source Institutions
In this simple and fun activity, learners build a tower of cups to explore distribution of weight. Learners make predictions about their towers and test their designs.

"Can" You Stand the Pressure
Source Institutions
In this activity about states of matter, learners get to witness firsthand the awesome power of air pressure. They watch as an ordinary soda can is crushed by invisible forces.

Hoopster: An Airplane Made from Paper Hoops
Source Institutions
This activity provides instructions for making an aircraft that can really fly using a straw and paper hoops!

Iodine Investigators!
Source Institutions
In this activity on page 7 of the PDF (Chemistry—It’s Elemental), learners use iodine to identify foods that contain starch.

How does the Atmosphere keep the Earth Warmer?
Source Institutions
In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

Exploring A Hydrogel
Source Institutions
In this activity on page 10 of the PDF, learners develop an experiment to answer the following question: "How much water can the hydrogel in a baby diaper hold?" Use this activity to explore polymers,

Squeezing Pictures Into Codes
Source Institutions
In this activity, learners will explore how computers represent pictures using pixels.

What Causes Wind?
Source Institutions
In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

Make Your Own Rain Stick
Source Institutions
This activity provides step-by-step instructions on how to build a rain stick, a musical instrument originating in South America.
