Family Fort Challenge
Source Institutions
In this activity, learners will explore engineering concepts to construct a blanket fort using materials sourced from home.

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

Apartment Buildings and More
Source Institutions
In this engineering activity, young learners investigate multi-level buildings.

DIY Weather Vane
Source Institutions
In this activity, learners will engineer their own weather vane. This activity includes step-by-step instructions with pictures and a "What's Happening?" section explaining how the activity worked.

How to Test The Strength of Shapes
Source Institutions
In this activity, learners explore the strength of different shapes. Fold paper into triangles, squares, and other shapes, then experiment with how much weight they can hold.

Engineer an Aeolipile
Source Institutions
In this engineering design challenge, learners build an air-powered spinning machine.

Engineer an Octopus Suction Pad
Source Institutions
In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

Building Tall
Source Institutions
In this engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.

As Straight as a Pole
Source Institutions
In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

Breaking Up with Combustion
Source Institutions
This activity teaches combustion as the interaction of a fuel source and oxygen.

Lego Man Jump
Source Institutions
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.

Paper Cup Stool
Source Institutions
In this activity, learners will explore how and why weight distribution works.

Tessellations
Source Institutions
In this activity, learners will engineer a new shape and use it to create a new pattern with no wasted space.

Zoomers
Source Institutions
In this activity, learners build their own rockets from paper, coffee stirrers, and tape. Learners discover that when anything flies, air pressure is always involved.

Cardboard Sculptures
Source Institutions
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.

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

Control a Bird’s Flight
Source Institutions
In this engineering design challenge, learners make a bird and then control its flight with attached strings.

Build a Bubble Circuit
Source Institutions
In this engineering design challenge, learners make a bubble maze that allows bubbles to move through a series of “on” and “off” switches.

Exploring Tools: Mitten Challenge
Source Institutions
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.

Mitten Challenge
Source Institutions
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.
