As Straight as a Pole
Source Institutions
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.

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

Rocket Pinwheel
Source Institutions
This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction.

Paper Bridges
Source Institutions
In this activity, learners build bridges using paper and explore how much weight each bridge design can support.

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

Clay Bridges
Source Institutions
In this activity, learners make bridges using an oil-based modeling clay (plasticene). The instructions include discussion questions for both before and after bridge building.

Prepare for a Dock Shop Field Trip
Source Institutions
In this activity, learners explore what makes a boat float and sink. They examine and test various objects to determine why objects float or sink.

Soapy Boat
Source Institutions
Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.

Vortex
Source Institutions
In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.

Building Tall
Source Institutions
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.

Levers at Play
Source Institutions
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).
