Bridge the Gap
Source Institutions
Learners work in groups to construct bridges using stale marshmallows and toothpicks.

Tall Tower Challenge
Source Institutions
In this activity, learners explore the design of tall structures such as skyscrapers and telecommunication towers.

Design a Park
Source Institutions
In this activity, learners are invited to imagine the park of their dreams!

Tall Tower Challenge
Source Institutions
In this activity, learners will use their chosen material to build the tallest tower possible in under three minutes. This activity uses problem solving and fine motor skills to challenge learners.

Fun with Speedboats
Source Institutions
In this activity, learners explore how boats are engineered to achieve speed.
Simple Submarine
Source Institutions
Using simple, inexpensive items, learners build and test submarine models.

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

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

Balsa Towers
Source Institutions
Learners work in groups to design and build a tower out of balsa wood. As a motivator, they can compete to build a tower with the highest strength-to-weight ratio.

Popsicle Bridge
Source Institutions
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

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.

Elevator Engineering
Source Institutions
In this activity, learners will use household items to design and build an elevator that will carry 2 passengers to a height of 16 inches...or higher!

Cup Towers
Source Institutions
In this activity, learners explore different ways to stack cups to meet a personal goal.

Levers at Play
Source Institutions
In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).

Milk Carton Boats
Source Institutions
This activity (on page 2 of the PDF SciGirls Activity: Milk Carton Boat) is a full inquiry investigation into boat hull design.

Wind Tunnel Testing
Source Institutions
In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.

Clipper Creations
Source Institutions
In this activity, learners create a working model of a nail clipper. This activity helps learners learn the basic principles of simple machines, engineering design and model building.

Shaking It!
Source Institutions
In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

Waterproof that Roof!
Source Institutions
In this activity, learners explore how engineers have improved roofing designs and materials in order to protect the contents of buildings.
