Source Institutions
In this outdoor activity, learners construct bird feeders and set them up at to investigate bird behavior for one or two weeks. Multiple feeder designs are suggested.
Pattern Sticks
Source Institutions
In this activity, learners compete to be the first to win twenty counting pieces. First, learners draw patterns on only one side of four craft sticks.

Blow It Away
Source Institutions
In this activity, learners design wind-powered cars out of simple household materials. Students have fun designing and then racing their vehicles around the room.

How Many Pennies?
Source Institutions
In this activity (pages 13-14), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

Wind Works!
Source Institutions
Learners will build and experiment with their own windmills made from simple household materials.

Geometry Construction: Polyhedral Playthings
Source Institutions
In this activity, learners create 3D geometric shapes using straws and pipe cleaners.

Origami Flying Disk
Source Institutions
In this three-part activity, learners use paper to explore Bernoulli's Principle — fast-moving air has lower pressure than non-moving air.

Paper Airplanes
Source Institutions
In this activity, learners explore the properties of paper by constructing and modifying paper airplanes.

Radial Chromatography
Source Institutions
How many colors make black? Gather as many water soluble black markers as you can find.

Make a Dinosaur
Source Institutions
In this activity, learners explore the size and scale of dinosaurs. Learners listen to "Dinosaurs, Dinosaurs" by Byron Barton to understand some background information about dinosaurs.
