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.
Glue Stick Sunset
Source Institutions
In this activity, learners explore why the sky is blue. Learners model the scattering of light by the atmosphere, which creates the blue sky and red sunset, using a flashlight and clear glue sticks.
How Big is Small
Source Institutions
In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.
Running in Circles
Source Institutions
In this group activity, learners use some common objects and work together to simulate the Coriolis effect. During the challenge, learners make predictions and test different scenarios.
Shell Shifts
Source Institutions
Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.
Hot Sauce Hot Spots
Source Institutions
In this activity, learners model hot spot island formation, orientation and progression with condiments.
CD Air Puck
Source Institutions
In this activity, learners will use a compact disc to build an air puck that can glide across a smooth tabletop. The puck glides with almost no friction on a cushion of air escaping from a balloon.
To Topo Two
Source Institutions
In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).
Chocolate (Sea Floor) Lava
Source Institutions
In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.
Toast a Mole!
Source Institutions
In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!
Earth Atmosphere Composition
Source Institutions
In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.
Fast Rusting
Source Institutions
In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.
Mold Mole Molds
Source Institutions
In this activity, learners make different shapes that hold exactly one mole of gas (air).
Atmosphere Composition Model
Source Institutions
In this activity, learners create a model using metric measuring tapes and atmosphere composition data.
Portable Potable Pressure
Source Institutions
In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.
Polar Opposites
Source Institutions
In this activity, learners make a 3-D model of magnetic fields by inserting a small, strong magnet into a sphere.
Bubble Suspension
Source Institutions
In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.
Blue Sky
Source Institutions
In this optics activity, learners explore why the sky is blue and the sunset is red, using a simple setup comprising a transparent plastic box, water, and powdered milk.
