In this activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.

Learners will understand the relationship between climate change and sea-level rise.

This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.

In this Cyberchase activity, learners use the numbers one through six to solve a puzzle.

In this activity, "space cadets" (learners) use writing and sequencing skills in addition to directional words/ordered pairs to guide Buzz Lightyear (from the movie "Toy Story") through a grid to reac

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this activity, learners explore the concept of how engineering solved the problem of human/computer interface.

In this activity, learners create a tiny electric, motorized dancer. Learners use the interactions of magnetism and electric current to make a wire spin, while displaying the Lorentz Force in action.

In this engineering activity, learners design parachutes to give toy figures safe landings. This activity is great for practicing an important STEM skill--changing only one variable at a time.

In this activity, learners play a game from India similar to Tic-Tac-Toe. Players take turns placing coins on the game board and sliding the coins along the spaces.

In this activity, learners explore the many uses of periscopes and how this simple device was designed and is used in many applications.

In this math activity, learners build Peppy the dog the best trail and park for running around.

In this activity about olfaction (7th activity on the page), learners use natural ingredients to concoct their own perfume.

In this math activity, learners pretend there is a special store that lets you pay for toys by their height in pennies.

In this engineering activity, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.

In this activity, learners use what they know about probability to figure out what is in a mystery bag. Learners analyze data to guess how many of each color crayons are in the bag.

In this activity (on page 2), one person "programs" the other like a robot to move through a space, trying to get them to avoid obstacles and reach a goal.

In this math activity, learners pretend there is a special store that lets you pay for toys by their weight in pennies.

In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.

In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.
