Rooftop Gardens
How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

Toilet Model
Source Institutions
In this activity, PVC pipe, plastic water bottles and vinyl tubing are used to make a simple working toilet model. The model shows the role of a siphon in the flushing of a toilet.

3...2...1 Puff!
Source Institutions
In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.

Build a Raft
Source Institutions
In this activity, learners explore density and buoyancy as they design and construct rafts.

Zero-Energy Housing
In this activity, learners investigate passive solar building design with a focus solely on heating.

Wind Turbine Blade Design
Source Institutions
In this activity, learners design, build and test wind turbines. Learners go through the design process and use the scientific method to test important blade variables.

Kites
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.
Up, Up and Away with Bottles
Source Institutions
In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

Designing a Wall
Source Institutions
In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.

Echo Base Bobsleds
Source Institutions
The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

Understanding Albedo
Source Institutions
In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

Biodomes Engineering Design Project
In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.

Model Wind Tunnel
Source Institutions
In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.

The Watershed Connection
Source Institutions
In this activity, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.

Foam Rocket
Source Institutions
In this activity, learners work in teams build and launch rubberband-powered foam rockets.

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.

Building a 3-D Space Maze: Escher Staircase
Source Institutions
In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

Build A Treetop Walkway
Source Institutions
Build and test a scale model of a rainforest canopy walkway.

Fun with Speedboats
Source Institutions
In this activity, learners explore how boats are engineered to achieve speed.

Supporting Structures
Source Institutions
In this activity about living things and gravity (page 5 of PDF), learners design and build an exoskeleton or an endoskeleton for an animal of their own invention.
