In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.

In this activity, learners map their world by drawing a plan of their bedroom.

In this activity, learners explore physics by building a catapult that launches marshmallows with household objects.

In this physics activity (page 6 of the PDF), learners will explore how static electricity affects surrounding objects.

In this activity, learners follow simple directions to explore and create platonic solids.

In this activity, learners make a model of a power plant that uses steam. Learners use simple materials like foil, a tin can, and a pot of water to model a geothermal power plant.

In this math activity (Page 11 of the Dining Out! PDF), younger learners count out the total amount of money needed to purchase trail mix using the fewest number of bills/coins possible.

Learners turn over a random selection of cards from a larger set. From the words revealed, they try to determine the sentence represented on the larger set of cards.

Learners investigate a pre-constructed mystery tube to determine its interior mechanism.

In this activity, learners make a photographic image—without a camera!

In this board game, learners explore the origins of meteors, meteoroids, and meteorites as well as the their characteristics and importance. They also discover some misconceptions about meteors.

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

In this tabletop board game, players will represent a team of scientists and engineers sending a spacecraft on a mission to space.

In this activity, learners analyze a fictionalized report of life on Mars, based on a real NASA satellite photo, and explore how to separate scientific fact from fiction.

During this lesson, learners will determine their blood pressure and learn about systolic and diastolic pressures.

In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.

In this activity, learners build and test a compass. Learners work in pairs and pretend they are stuck in the wilderness at night.

In an investigation called "Shape It!" learners craft tiny boats out of clay, set them afloat on water and then add weight loads to them, in order to explore: how objects stay afloat in water; what th

Learners listen to and try to decipher a radio message that was sent from Earth to possible intelligent civilizations.

Directed by instructional cards, learners kinesthetically model cell communication by acting as components in a cell signaling pathway.
