In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

Each group of learners uses everyday materials, such as paper, toothpicks, and tape to design and construct a structure intended to support the weight of a cinder block for 30 seconds.

In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

Learners explore the field of civil engineering by making a bridge using spaghetti as their primary building material.

In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).

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