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.

In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.

In this activity, learners investigate the properties of different types of balls.

Learners construct and launch paper helicopters.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

In this activity, learners explore how boats are engineered to achieve speed.

In this activity, learners explore the concept of how aerospace engineering has impacted sports, specifically exploring the design of golf balls.

In this activity, learners explore the function and engineering of dams and how dams have many uses and solve many problems in the world.

Learners initially test to see how many drops of liquid (water, rubbing alcohol, and vegetable oil) can fit on a penny.

Learners design their own experiment to determine conditions that either help or hinder the decomposition of carrots by soil microbes.

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, challenge learners to keep an ice cube from completely melting in 30 minutes. Learners engineer a box or wrap to prevent an ice cube from melting.

In this activity, learners explore chemical engineering and how the processes of chemical plating and electroplating have impacted many industries.

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 activity, learners explore the unique challenges in transportation engineering, such as devising a method for skiers or hikers to get to the top of a mountain.

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, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.

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

In this engineering activity, challenge learners to invent a water filter that cleans dirty water.
