A Funny Taste
Source Institutions
In this activity, learners explore the different salinities of various sources of water by taste-testing.
How Much Water is in that Cloud?
Source Institutions
In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.
Salt 'n Lighter
Source Institutions
In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.
Diet Light
Source Institutions
In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.
Earth's Energy Cycle: Albedo
Source Institutions
In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.
It's a Gas, Man
Source Institutions
In this activity, learners discover if carbon dioxide has an effect on temperature.
The Carbon Cycle and its Role in Climate Change: Activity 3
Source Institutions
In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.
Crunch Time
Source Institutions
In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.
Measure the Pressure: The "Wet" Barometer
Source Institutions
In this activity, learners use simple items to construct a device for indicating air pressure changes.
Trash Traits
Source Institutions
In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.
Toasty Wind
Source Institutions
In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.
The Carbon Cycle and its Role in Climate Change: Activity 1
Source Institutions
In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.
Waves and Tides
Source Institutions
In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.
A Pressing Engagement
Source Institutions
In this quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads.
The Carbon Cycle and its Role in Climate Change: Activity 2
Source Institutions
In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause
Go with the Flow
Source Institutions
In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.
We all Scream for Ice Cream
Source Institutions
In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.
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.
Leaf it to Me
Source Institutions
In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.
