Up, Up and Away with Bottles
Source Institutions
In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

Globe at Night
Source Institutions
In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

Heart of the Matter
Source Institutions
In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

The Shadow Knows II
Source Institutions
In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

Pot-in-Pot Refrigeration
Source Institutions
In this activity (on page 2 of PDF), learners create a low-tech refrigerator that requires no electricity to keep food from spoiling.

Equatorial Sundial
Source Institutions
In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

Ancient Sun Observations
Source Institutions
In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.

Weather Vane and Anemometer
Source Institutions
In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

Measuring the Wind
Source Institutions
In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

Water Rocket Launch
Source Institutions
In this activity, learners explore rocketry and the principals of space flight.

Rocket Wind Tunnel
Source Institutions
In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

Monitoring Amphibians
Source Institutions
In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

Oil Spot Photometer
Source Institutions
In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

Build Your Own Solar Oven
Source Institutions
Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.

Backyard Biodiesel
Source Institutions
In this activity, learners make a small batch of biodiesel that will work in any diesel engine. Learners use an old juice bottle as a "reactor" vessel to chemically process vegetable oil into fuel.

Waterproof that Roof!
Source Institutions
In this activity, learners explore how engineers have improved roofing designs and materials in order to protect the contents of buildings.

Does Sunscreen Protect My DNA?
Source Institutions
In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

The Parachuting Egg
Source Institutions
In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

FlyBy Math: Distance-Rate-Time Problems in Air Traffic Control
Source Institutions
In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.
