Learners determine the surface area and volume of two identical boxes, and then figure out the dimensions of a cubical box with the same volume.

Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.

MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

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

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

In this activity, learners explore the strength of different shapes. Fold paper into triangles, squares, and other shapes, then experiment with how much weight they can hold.

In this activity, learners explore how the hull shape impacts a ship's performance and stability.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

Using simple, inexpensive items, learners build and test submarine models.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

In this two part activity, learners work in pairs or individually to discover how vectoring the thrust from a jet engine affects movement of an airplane.

In this sports-themed engineering activity, learners create super bouncy balls out of balloons. Learners brainstorm, test their designs, and share results.

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

Learners construct one or more of the following kinds of sundials: a shadow plot, a horizontal sundial, and a diptych sundial.

In this engineering activity, learners construct sturdy geodesic structures out of gumdrops and toothpicks. Use this activity to explore engineering principles as well as sturdy shapes and triangles.

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.

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

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, learners design a bungee jump for an egg using nylon stockings.
