For the Birds
Source Institutions
In this activity, learners will explore nature by creating food for birds. Learners will develop fine motor skills and engage in nature observation through this activity.

Ice Roads: Steiner Trees
Source Institutions
In this outdoor activity, learners use pegs (like tent pegs) and string or elastic to simulate drill sites and roads in Northern Canada.

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.

Strong Shapes
Source Institutions
Is a square stronger than a triangle? Use tongue depressors to build simple shapes. Then apply a little weight to them and see what happens!

Trail Impact Study
Source Institutions
In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

Straws and Airplanes
Source Institutions
Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.

Using a Simple Astrolabe
Source Institutions
In this activity, learners use an astrolabe to measure the altitude of objects. Learners will first practice taking measurements by measuring the altitude of trees and buildings.

Solving Playground Network Problems
Source Institutions
In this activity, learners use cooperation and logical thinking to find solutions to network problems on the playground.

Personal Pinhole Theater
Source Institutions
Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

Polarized Sunglasses
Source Institutions
In this activity, learners explore how polarizing sunglasses can help diminish road glare.

Building Tetrahedral Kites
Source Institutions
Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.

Floodplain Modeling
In this design-based lesson, learners study flood dynamics as they modify a riverbed with blockages or levees to simulate real-world scenarios.

Speedy Shelter
Source Institutions
In this design challenge activity, learners invent an emergency shelter that can fit a person and is sturdy and quick to build.

Construction and Destruction
Source Institutions
In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.

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.

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.

My Angle on Cooling: Effects of Distance and Inclination
Source Institutions
In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

FlyBy Math: Distance-Rate-Time Problems in Air Traffic Control
Source Institutions
In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.
