In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

Learners build simple catapults and use them to launch cotton balls.

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.

Computers are often used to put lists into some sort of order—for example, names into alphabetical order, appointments or e-mail by date, or items in numerical order.

In this activity, learners collect worms and then observe how they move.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

In this activity, learners discover how solar energy can be used to heat water.

Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.

In this wintertime outdoor activity, learners role play wolves tracking their prey by following scented trails.

In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.

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

In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the

In this investigation learners explore the differences between, and interdependence of, living and nonliving elements in a water ecosystem.

In this activity, learners construct an indoors obstacle course and discover how using an eye patch can help them complete the course in the dark.

In this activity, learners create a mixture of water, alcohol and permanent marker ink, and then add salt to form a colored alcohol layer on top of a colorless water layer.

Learners build a pendulum from a yo-yo, and then design their own experiment to determine what affects the pendulum's period of swing.

In this design challenge activity, learners modify a cup so it can carry a marble down a zip line and also drop it onto a target.

In this activity, learners take apart a used zinc-carbon dry cell battery.

In this activity, learners explore the concept of friction and how ball bearings reduce friction.
