Delta, Delta, Delta
Source Institutions
In this experiment, learners construct an equilateral triangle using graph paper, a pencil, protractor and ruler. They also make a "laser triangle" using a laser pointer and front-silvered mirrors.

How Can Gravity Make Something Go Up?
Source Institutions
In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.

Landing the Rover
Source Institutions
In this team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF).

Ocean Acidification in a Cup
Source Institutions
Ocean acidification is a problem that humans will have to deal with as we release more and more carbon dioxide into the atmosphere.

Good News: We're on the Rise!
Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.

Sandy Samples
Source Institutions
In this collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.

Acid Rain Effects
Learners conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.

Name-a-Saurus
Source Institutions
In this paleontology activity, learners explore the system behind dinosaur nomenclature.

Cartesian Diver
Source Institutions
In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

What's Hiding in the Air?: Acid Rain Activity
As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

A Recipe for Air
Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

Amazing Marshmallows
Source Institutions
In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

Floating Paper Clip
Source Institutions
In this activity, challenge learners to float a paper clip in a cup of water. Learners discover that a paper clip will sink in a cup of water, except when it is placed on a piece of paper towel.

An Apple as Planet Earth
Source Institutions
In this environmental education demonstration (page 6 of the PDF), learners will see a tangible representation of the scarcity of soil resources on earth.

How Are Soils Classified?
Source Institutions
In this activity about soil (page 7 of the PDF), learners will use their sense of touch as well as sight to understand how soil is classified based on texture and other details.

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

The Pull of the Planets
Source Institutions
In this activity, learners model the gravitational fields of planets on a flexible surface.

Space Stations: Sponge Spool Spine
Source Institutions
In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

Sidewalk Constellations
Source Institutions
In this activity, learners will go outside and create a constellation.

Radioactive Decay of Candium
Source Institutions
In this simulation, learners use M&M™ candy to explore radioactive isotope decay.
