In this activity, learners explore how engineers work in a team to solve problems.

In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit

In this activity, learners are challenged to design a wind-powered car using only a handful of household materials.

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 will engineer a water irrigation system. Learners will create a ditch irrigation system -- or an acequia-- to move water with the help of gravity.

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

In this engineering design challenge, learners build an air-powered spinning machine.

In this design challenge activity, learners modify a cup so it can carry a marble down a zip line and also drop it onto a target.

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 explore the devices used over time to measure changes in temperature.

In this activity, learners are challenged to create a parachute using easily sourced materials in order to transport a LEGO figure safely to the ground.

In this activity, learners will explore how and why weight distribution works.

Learners build simple catapults and use them to launch cotton balls.

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

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.

In this design challenge, leaners attempt to build a strong structure out of LEGO® bricks that can withstand a 4-foot drop.

In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.

In this activity, learners explore the concept of friction and how ball bearings reduce friction.

In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.
