Learners play the role of materials engineers as they test the flexibility of different materials.

Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

Learners conduct two activities to investigate two properties of liquids: density and viscosity. In a clear container, learners stack 7 different liquids which will layer according to their density.

In this activity, learners investigate passive solar building design with a focus solely on heating.

Learners create beautiful fluid motion. They explore fluid dynamics, surface tension, solubility, and buoyancy while mixing liquids together.

In this activity (pages 42-49), learners discover the methods and challenges of building nanoscale structures with macroscale equipment.

In this activity, learners explore how a flashlight works, showing the electric circuit and switch functions of this everyday household item.

The goal of this activity is to design the fastest sailboat or one that carries the most treasure.

In this activity, learners explore how product design differences can affect the success of a final product -- in this case a bag for holding candy.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh

In this activity, learners are introduced to challenges of maintaining temperatures while living in space.
