The Carbon Cycle: How It Works
Source Institutions
In this game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another
That Sinking Feeling
Source Institutions
In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.
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.
Penny Drop
Source Institutions
In this quick activity about the properties of water (page 1 of PDF under SciGirls Activity: Malformed Frogs), learners will use an eyedropper to slowly place one drop of water at a time onto a penny,
Dinosaur Breath
Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.
Moving Without Wheels
In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.
Hot Stuff!: Carbon Dioxide Extinguishes a Flame
In this demonstration, learners observe vinegar and baking soda creating carbon dioxide (CO2) in a bottle. The gas is poured out of a bottle onto a candle flame, putting out the candle.
Diatom Ooze: Ooze Clues
Source Institutions
In this activity, learners will plot the distribution of various oozes using information from sediment maps.
Estuaries
Source Institutions
An estuary is a body of water that is created when freshwater from rivers and streams flows into the saltwater of an ocean.
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.
Indicating Electrolysis
Source Institutions
In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.
Mold Mole Molds
Source Institutions
In this activity, learners make different shapes that hold exactly one mole of gas (air).
Submarine: Lift Bag Lander
Source Institutions
In this activity (on page 4), learners create a submarine using a plastic sandwich bag. This is a fun way to learn about buoyancy and how captured gas can cause objects to float.
Treasures in the Rough
Source Institutions
In this archaeology activity, learners make observations and conduct an experiment to demonstrate the effect saltwater has on artifacts.
What's So Special about Water: Solubility and Density
Source Institutions
In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.
Nuclear Fusion
Source Institutions
This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.
Ocean in a Bottle
Source Institutions
In this activity, learners consider how oil spills behave in the ocean and what impact they have on marine wildlife.
Make Your Own Deep-Sea Vent
Source Institutions
In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.
Let's Go Ice Fishing
Source Institutions
In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.
Hot Stuff!: Creating and Testing for Carbon Dioxide
In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.
