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.

In this activity, learners use information gathered from a variety of sources to design and make their own insect.

In this activity, learners determine whether thermal energy can be used for work.

In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marin

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

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 experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

This lesson focuses on molecular motion in gases. Learners compare the mass of a basketball when it is deflated and after it has been inflated.

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

In this activity (on pages 6-11), learners work as a team to investigate how impact craters on Earth, the Moon or other planets take shape and what patterns they make.

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

In this activity (on pages 26-33), learners play parasitologists, solving several "mysteries" about people who got sick from various parasites. In teams of four, each member solves one mystery.

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

In this math activity, based on the research of famed astronomer Frank Drake, learners calculate the possibilities of finding intelligent life elsewhere in the universe besides Earth.

This activity guide includes instructions on how to build a "Shake Table" by mounting an eccentric mass (off center) on the shaft of a small dc motor.

Learners examine the manufacturing process while they make picture frames from cereal boxes.

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

In this outdoor activity, learners make models of homes that might protect small animals from the elements, then search living plants for real structures made by small animals.

In this lesson plan, learners examine some of the of greenhouse gas emissions sources in their community.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.
