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

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

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 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.

Learners build a model of the planets in the solar system. In their model, the planets are spaced in their relative distance from the Sun.

In this activity, leaners explore building techniques by recreating the story of The Three Little Pigs.

In this activity (page 4 of the pdf), learners build a model of a tide pool, using chicken wire, paper mache, and other craft materials.

In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.

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.

In this engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.

In this activity, a group of learners work collaboratively to design and construct a paper model showing the evolution of an environment through multiple stages, from prehistory through the modern cit
