In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.

In this activity, learners explore the concept of how engineering has made possible the development of--and ongoing improvements to--adaptive devices that serve to help individuals with a wide range o

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

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

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

Historically, sea floor mapping (bathymetry) was done by soundings.

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

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

Each learner chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days.

In this engineering activity, learners design and build a mechanical arm to lift a small item.

In this activity, learners explore the concepts of structural engineering and how to measure the critical load, or the maximum weight a structure can bear.

In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

Students design and build their own parachutes in this hands-on engineering project.

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 engineering activity, young learners investigate multi-level buildings.

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

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

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

In this activity, learners will test the strength of different brands of paper towels.

In this activity, learners explore how voting systems have changed with engineering advances over time. Learners work in teams to design their own voting system using easy to find materials.
