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.

Launch It
Add to list DetailsIn this design challenge activity, learners use a balloon and other simple materials to design an air-powered rocket that can hit a distant target.

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.

Be a Scanning Probe Microscope
Source Institutions
In this activity, learners investigate Scanning Probe Microscopes (SPM) and then work in teams using a pencil to explore and identify the shape of objects they cannot see, just as SPMs do at the nano

Water Illusions: Refraction & Magnification
Source Institutions
Learners demonstrate how water can distort, refract and magnify light.

Super Spinner
Source Institutions
In this activity (page 1 of PDF under SciGirls Activity: Pet Handedness), learners will construct a simple spinning top out of a circle of construction paper, a film canister lid, and a bamboo skewer.

Chew that Gum
Source Institutions
In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.

Underwater Fireworks
Source Institutions
In this activity, learners investigate diffusion by creating underwater "fireworks" using food coloring, oil and water.

Bubble Tray
Source Institutions
In this activity, learners use simple materials to create giant bubbles.

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.

Mystery Boxes for Grades 3-5
Source Institutions
Learners manipulate opaque, sealed boxes and attempt to determine their interior structures. Each box contains a moving ball and one or more fixed barriers.

Cat's Meow
Source Institutions
In this chemistry activity, learners are asked to form a hypothesis about the behavior of milk as household detergents act upon it.

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.

Composite Materials
Source Institutions
This is an activity (located on page 3 of PDF under Hockey Sticks Activity) about composites, materials made of 2 or more different components.

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

Linear Functions: Mystery Liquids
Source Institutions
In this math lesson, learners analyze the density of liquids in order to explore linear functions.
