Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle.

Historically, sea floor mapping (bathymetry) was done by soundings.

This activity (located on page 4 of the PDF under GPS: Sea Turtles Activity) is a full inquiry investigation into testing a repair material.

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.

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

In this activity about electricity, learners imagine that they are out in the wilderness and it is getting dark. Their task is to use the materials supplied to build a simple flashlight.

Learners work in groups to build model cars from paper parts. First, each learner builds cars individually and the group times themselves.

In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.

In this yummy earth science activity (page 5 of the PDF), learners use fudge to learn about different kinds of lava.

In this outdoor activity, learners play a game of Tag to discover how neurons attach themselves to each other to form a chain.

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

In this online Flash game, learners test their engineering know-how, moving a collection of mechanical parts onto a board to make complete a system of parts that will move a ball from start to finish.

In this forensics activity, learners solve a mystery using “DNA” taken from the scene of the crime.

In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.

This is an outdoor activity designed to demonstrate evolution of feeding behavior in flocking, schooling or herding animals that maximizes allocation of food resources and enhances survival.

In this activity, learners create their own archaeological profiles.

This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.

In this simulation game, learners play as predators equipped with genetically different “mouths” (utensils) and hunt for “prey” (assorted beans).

In this activity, learners use simple materials to simulate the effect of X-rays in a safe way. Learners place a piece of window screen over a box and a cardboard pattern on top of the screen.

This activity (on pages 23-27) lets learners simulate the work of scientists who take core samples of Earth's rocky layers to determine geological history.
