Water: Clearly Unique!
Source Institutions
In this activity on page 4 of the PDF (Water in Our World), learners conduct some quick and easy tests to determine the differences between water and other liquids that look very similar to water.
Pepper Scatter
Source Institutions
In this quick activity, learners break the tension that happens when water develops a "skin." Learners use water, pepper and some soap to discover the wonders of surface tension—the force that attract
Can Crushers
Source Institutions
In this activity, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.
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,
Inverted Bottles
Source Institutions
In this activity, learners investigate convection by using food coloring and water of different temperatures.
What's So Special about Water: Surface Tension
Source Institutions
In this three-part activity, learners play a game and conduct two simple experiments to explore water and surface tension. Learners will have fun discovering how water "sticks" together.
Water Cycle in a Bag
Source Institutions
In this activity, learners create a biosphere in a baggie.
Air Pressure
Source Institutions
In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.
Having a Gas with Water
Source Institutions
In this activity, learners construct a simple electrolysis device. With this device, learners can decompose water into its elemental components: hydrogen and oxygen gas.
