This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

In this activity, learners explore the engineering and principles behind working elevators.

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

Learners explore the field of civil engineering by making a bridge using spaghetti as their primary building material.

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 activity, learners explore how engineering has developed various means to remove impurities from water.

In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

In this activity learners will build roller coasters and test them using small balls or marbles.

Learners set up books with rubber bands stretched between the books. When two identical books are stretched apart and released, they move back toward each other an equal distance.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.

Learners engage in close observation of falling objects. They determine it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.

Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.

In this activity, learners demonstrate and discuss simple circuits as well as the differences between parallel and serial circuit design and functions.

In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.

In this activity, learners explore computer programming and the impact of computers on society. Learners build and test a program to turn a light on and off using an Arduino board.
