Nature Journals
Source Institutions
In this activity, learners construct a home-made journal with simple, everyday materials.

Measuring Wind Speed
Source Institutions
In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

Pop Rockets
Source Institutions
Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

Parachuting Pinwheel
Source Institutions
Build a pinwheel that works without wind! This activity contains steps on how to build a parachuting pinwheel out of paper, a film canister, and some brads.

Pinhole Viewer
Source Institutions
In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

Pedal Power
Source Institutions
In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.

Rain Machine (Solar Still)
Source Institutions
In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

Gravity Fountains
Source Institutions
This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

Carbon Sequestration
Source Institutions
In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra

Equatorial Sundial
Source Institutions
In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

Oil Spot Photometer
Source Institutions
In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

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.
