Building Houses: Build a Cardboard Tube House
Source Institutions
Build a house you can fit inside, using cardboard tubes.

Exploration Vehicles
Source Institutions
Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).

Trail Construction
Source Institutions
In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.

Sand Dunes
Source Institutions
This outdoor activity (on page 2 of the PDF under SciGirls Activity: Sand Dunes) is a full inquiry investigation into how the amount of moisture in a sand dune relates to the number of plants growing

Traveling Networks
Source Institutions
In this geometry activity, learners explore networks painted on playgrounds, such as a four square court, and draw their own.

Family Flyers
Source Institutions
In this activity, learners work in teams to build and test paper airplanes. Learners try to fly their airplanes directly on the runway and earn points for accuracy.

Metal Heads
Source Institutions
Pairs of learners play the roles of programmer and robot. The programmer gives specific directions to the robot to accomplish a simple task (e.g. walk across the room and pick up a pencil).

Air Pressure and Dent Pullers
Source Institutions
In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

Sky Floater Challenge
Source Institutions
In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

Soccer Kicks
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Soccer Ball Kick) is a full inquiry investigation into transfer of motion.

Crazy About Kites
Source Institutions
In this activity, learners build a kite out of paper, change it, and try to make it fly even better. With their new knowledge of kite making, students can then go on to create their own kite designs.

Bike Bling
Source Institutions
In this activity, learners will trick out their bike with crafts and flair. Learners will explore symmetry, cause and effect and design through this activity.

Self-Assembly Game
Source Institutions
This is a quick game about self-assembly (page 2 of PDF under Self-Assembly Activity). Like the molecules of DNA, learners will self-assemble into a pattern by following a simple set of rules.

String Shapes
Source Institutions
In this activity, learners work together to make polygons (many-sided shapes) with string. Learners sit on the floor and hold onto a piece of string slid between their thumbs and index fingers.
