In this math activity, learners experiment with the concept of symmetry.

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 math lesson, learners play two different games to help them understand coordinates. First, learners read the book, "The Fly on the Ceiling," by Julie Glass.

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 design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.

In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

Make a one-string "guitar" by stringing a cup with some fishing line. You amplify the plucking of the string by placing a piezo contact microphone and mini battery powered amplifier inside the cup.

In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

Students design and create their own air-powered rockets, in this hands-on activity.

In this activity, learners explore dinosaur skeletons, anatomy, and locomotion. Learners compare and contrast dinosaur skeletons and drawings.

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.

In this activity, learners create 3D geometric shapes using straws and pipe cleaners.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "Dinosaurs, Dinosaurs" by Byron Barton to understand some background information about dinosaurs.

In this activity, learners use simple materials and basic tools to construct a special toy to explore pendulums. As the head of the toy bobs one way, the eyeballs bob the other way.

In this activity, learners design wind-powered cars out of simple household materials. Students have fun designing and then racing their vehicles around the room.

In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.

The goal of this activity is to design, build and test a house or toy for an animal.

In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.

In this activity, learners use maps to locate the Arctic region and use a word game to discover the types of resource people need to survive in the extreme climate.

This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.
