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

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 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 the design of tall structures such as skyscrapers and telecommunication towers.

In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

In this engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.

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 hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.

In this activity, learners explore the devices used over time to measure changes in temperature.

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

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.

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

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

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

This design challenge is an open-ended exploration of linkages, a group of parts connected by hinges, and the types of motion they can create.

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

In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat
