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, learners are invited to imagine the park of their dreams!

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

In this activity, learners will explore how and why weight distribution works.

In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.
