Learners explore the endless possibilities of cardboard engineering in this open-ended STEAM activity. Practice being creative by building structures with no glue, only cardboard and scissors.

Make a model city happier with LEDs, circuits, motors, and batteries! Groups can think, discuss, design, and build what would make a community happy. Kids can work as part of a team or on their own.

In this activity, learners will engineer three different parachutes to test how well each one works.

In this online Flash game, learners test their engineering know-how, moving a collection of mechanical parts onto a board to make complete a system of parts that will move a ball from start to finish.

In this engineering activity, learners design parachutes to give toy figures safe landings. This activity is great for practicing an important STEM skill--changing only one variable at a time.

No glue is needed for learners of any age to become marshmallow architects or engineers.

Learners recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and learners perform several velocity calculations.

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

Learners observe and discuss a simple model of a wet scrubber, a device for cleaning industrial air pollution.

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

Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.

Learners observe and discuss a vacuum cleaner as a model of a baghouse, a device used in cleaning industrial air pollution.

In this robotics activity, learners find ways to express emotions and feelings using only body movements, not facial expressions.

In this activity, learners design and build a NASA rover using raw pasta and candy with a limited imaginary budget.

Learners create an electrical-circuit maze out of wire, then try to pass a paperclip through the maze without touching the wire.

Based of the The Tech Challenge 2015, learners will engage in two mini-design challenges related to seismic engineering.

Learners act as engineers and design mini submarines that move in the water like real submarines.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.
