Spill Spread
Source Institutions
In this simulation, learners explore how ocean currents spread all kinds of pollution—including oil spills, sewage, pesticides and factory waste—far beyond where the pollution originates.

For the Birds: Environmental Effects on Population
Source Institutions
In this activity, learners will investigate how shorebirds and seabirds are extremely vulnerable to changes in their environment, whether human-induced or otherwise.

Fun with Speedboats
Source Institutions
In this activity, learners explore how boats are engineered to achieve speed.

Trip Wire
Source Institutions
In this activity, learners build simple alarms that they can attach to anything, such as a drawer or doorway. This activity introduces learners to electricity, circuits, and currents.

Exploring at the Nanoscale
Source Institutions
This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

Motor Bird
Source Institutions
In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.

Earth Attractions
Source Institutions
In this activity, learners build and test a compass. Learners work in pairs and pretend they are stuck in the wilderness at night.

Paddle Boat
Source Institutions
In this activity, learners build an old-fashioned paddle boat out of simple materials.

Kites
Source Institutions
In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

Take a Plant to Lunch
Source Institutions
Learners make a "menu" of any plants in their lunch for Monday through Friday and draw the plants from their lunch.

Radial Chromatography
Source Institutions
How many colors make black? Gather as many water soluble black markers as you can find.

Prehistoric Climate Change
Source Institutions
In this online interactive, learners use fossils to infer temperatures 55 million years ago, at the sites where the fossils were found.

Erosion
Source Institutions
In this activity, learners model erosion using a clear shoebox and sand or soil.

A Dissolving Challenge
Source Institutions
In this activity, learners add objects and substances to carbonated water to discover that added objects increase the rate at which dissolved gas comes out of solution.
How Does Water Climb a Tree?
Source Institutions
In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.

Evolution in Plane Sight
Source Institutions
In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.

Bones
Source Institutions
In this health activity (page 5 of the PDF), learners will explore a unique connection betweeen the bones of the body.

Wash This Way
Source Institutions
In this activity on page 4 of the PDF, learners investigate the importance of washing their hands.

Water: Clearly Unique!
Source Institutions
In this activity on page 4 of the PDF (Water in Our World), learners conduct some quick and easy tests to determine the differences between water and other liquids that look very similar to water.

Experiencing Parallax With Your Thumb
Source Institutions
In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.
