Pop Can "Hero Engine"
Source Institutions
In this activity, learners build water-propelled engines from soft drink cans.

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.

Engineer A Bird Feeder
Source Institutions
In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.

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.

Low-Tech Water Filter for High-Impact Clean
Source Institutions
In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

Chain Reaction II
Source Institutions
In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.

Exploring the Solar System: Mission to Space Board Game
Source Institutions
In this tabletop board game, players will represent a team of scientists and engineers sending a spacecraft on a mission to space.

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.

Balls and Ramps
Source Institutions
In this activity, learners use simple, everyday materials to experiment with balls and ramps.

Design a Seed
Source Institutions
In this activity, learners will design a seed and test how it travels. Learners will use the Engineering Design Process to create a seed which can move from place to place.

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

Make Pooter
Source Institutions
In this activity, learners will explore engineering to construct an insect collecting tool (insect aspirator). The pooter uses suction to safely collect smaller insects that nets miss or may injure.

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.
