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

In this activity, learners will predict the size of a giant scale model of a comb or other rectangular object, then make one. If you tripled the size of a dollar bill, could you sit on it?

Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.

In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.

Is a square stronger than a triangle? Use tongue depressors to build simple shapes. Then apply a little weight to them and see what happens!

In this activity, learners use recycled materials to build a bridge that holds as many potatoes as possible. They investigate weight, height, strength, and measurement as they seek design solutions.

In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.

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 explore dinosaur skeletons and anatomy. Learners make observations about a T. rex skeleton diagram and then measure the skeleton length and width.

This activity introduces learners to the structure and properties of carbon nanotubes.

Build a house you can fit inside, using cardboard tubes.

This activity is a hit for family events and all ages—some will finish in 45 minutes; others can go on for hours.

In this three-day lesson, learners identify two-dimensional shapes used in castle construction, create a castle collage using assorted shapes, and design tapestries using repeated patterns of color, s

In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.
