In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp

In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.

With two stacks of books and a few rolls of pennies, build two kinds of bridges--a beam span and an arch span--and see how much weight each of them can hold.

In this engineering activity, challenge learners to construct a paper bridge that can support 100 pennies.

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 engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

In this activity, learners use things from the kitchen as building materials to explore how shapes contribute to the strength of different structures.

In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit

This is a quick activity (on page 2 of the PDF under Hockey Sticks Activity) about how the arrangement of carbon atoms determines carbon's different properties.

In this activity, learners build bridges out of newspaper and tape to explore how structures are designed to bear loads.
