In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

In this activity (pages 13-14), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

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.

This is an activity (located on page 3 of the PDF) about the mixture of materials in bone and how they affect its strength.

This activity (on page 2 of the PDF under SciGirls Activity: Hockey) is a full inquiry investigation into how a hockey stick’s flex affects shooting power and accuracy.

In this activity, learners test and compare the physical properties of thermoplastic polymers. Learners compare different plastics based on their color, degree of transparency, texture, and density.

In this activity, learners explore the concept of conducting or insulating electricity.

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.

In this activity on page 11 of the PDF, learners follow simple steps to recycle old newspaper into new paper.

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

In this activity, learners explore how engineers design tire treads to increase safety and reliability.

In this activity, learners use three types of cheesy snacks--cheese balls, cheese puffs, and Cheetos--to learn about polymers.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

Learners apply their knowledge of heat transfer to design two cans - one that will retain heat and one that will cool down quickly.

In this activity, learners discover why only some types of plastic can be recycled.

In this activity, learners determine the elastic and plastic properties of different types of metal wires.

In this activity (pages 8-9), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.
