In this activity, learners complete a series of drawing activities to explore scale and powers of 10. Learners first trace each other on 1-meter-square pieces of paper.

In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

In this activity, learners are challenged to design and construct a windmill to harness the power of wind.

In this activity, learners are challenged to design and build a system of gears and kinematics to create a hand-stamping machine.

In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.

Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.

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

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

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity, learners are challenged to design, build and test a birdhouse that will stay cool in the sun.

This game uses a modified Uno deck to review concepts related to stem cell research and diabetes.

In this activity, learners explore the structural strength of triangles by creating their own free-standing geodesic dome out of plastic straws.

In this activity, learners construct three optical illusion toys to examine how our brains play tricks on what we see.

In this activity, learners will use a variety of household and/or natural objects to design a sculpture that balances from a single point.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

In this twist on a classic design challenge, learners will try to stop a bouncy ball from bouncing as they explore how to control the fall of an object.

In this activity, learners are challenged to build a bird feeder using recycled materials from home and are encouraged to problem solve during the extensions.

In this activity, learners will discover how to make butter from scratch. One optional tips includes adding marbles to speed up the process.
