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 genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

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 described on pages 2-3 of the PDF, participants debate whether there there's life elsewhere in the universe.

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 investigate stress and strain by designing, building, and testing beams made from polymer clay.

Learners explore the physical properties of a variety of balls and how they bounce.

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

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.

Bones are stiff, which helps us lift heavy things and walk around, but they are also somewhat flexible, which lets them bend slightly.

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.

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

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

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

This is written as a static display, but can easily become a hands-on experiment for learners.

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