In this activity, learners participate in a scavenger hunt, searching for and recognizing minerals and products that contain minerals.

In this design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.

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

Learners work with plastic sheeting, masking tape, and string to design the perfect material for plastic chair webbing, and then construct their webbing.

Learners examine the manufacturing process while they make picture frames from cereal boxes.

This activity/demo introduces learners to aerogel, a glass nanofoam. Learners discover how aerogel is made and how well it insulates as well as learn about aerogel's other unique properties.

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.

In this activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.

In this activity, learners explore the devices used over time to measure changes in temperature.

In this activity, learners explore how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count.

In this activity about human interface design issues, learners help the Oompa-Loompas of a great chocolate factory solve different problems.

In this activity, learners collect, categorize, weigh and analyze classroom trash and discuss ways that engineers have helped to reduce solid waste.

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

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

Learners look at labels on items in the room to determine where each item was manufactured, then write about the item on an index card.

This lesson focuses on graphene and its electrical properties and applications.

In this activity, learners explore the potential of interchangeable standard parts to create a large number of unique creations in different combinations.

In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.
