Computers store drawings, photographs, and other pictures using only numbers. Through this activity, learners decode numbers to create pictures using the same process that computers use.

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

In this activity, learners discover that the human brain is highly adaptable. Learners try to toss beanbags at a target while wearing prism goggles.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most. Then, learners estimate the size of a Triceratops and T.

In this activity, learners play a game and use pattern blocks to explore mirror images and reflection.

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

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

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

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.

In this activity, learners explore why animals, specifically dinosaurs, live in families.

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

In this math lesson, learners arrange pattern blocks to create tessellations and to explore geometric patterns. Learners first explore making patterns with a variety of pattern blocks.

In this math lesson (on Page 13), learners predict and simulate the likelihood of an event occurring.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

In this fun group activity involving music and movement, learners are introduced to the idea that many insects walk by using their legs to create "alternating triangles." Learners sing the "Ants Go Ma

In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.
