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.
Surface Tension Icebreaker
Source Institutions
This is a quick activity (located on page 2 of the PDF under Nasturtium Leaves Activity) about surface tension.
From Here to There
Source Institutions
In this water activity, learners discover ways to move water across the water table.
Be a Plumber
Source Institutions
In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.
What's So Special about Water: Absorption
Source Institutions
In this activity about water's cohesive and adhesive properties and why water molecules are attracted to each other, learners test if objects repel or absorb water.
Water Underground
Source Institutions
Many people get water from a source deep underground, called groundwater.
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.
Spill Spread
Source Institutions
In this simulation, learners explore how ocean currents spread all kinds of pollution—including oil spills, sewage, pesticides and factory waste—far beyond where the pollution originates.
What Causes Wind?
Source Institutions
In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.
Wet Art
Source Institutions
In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.
Shake and Break
Source Institutions
In this activity, learners will model the mechanical weathering and erosion of rocks in a stream or river.
Go with the Flow
Source Institutions
Learners draw comic-style pictures to show the water cycle. From a starting picture, one learner draws what happens to the water in the next panel, then passes the comic strip to another learner.
The Best Dam Simulation Ever
Source Institutions
This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.
Wetland Filter Model
Source Institutions
In this quick activity (located on page 2 of the PDF under GPS Wetlands Activity), learners will model how wetlands act as natural filters for the environment.
A Hole in the Ground
Source Institutions
Learners build models of sinkholes to gain an intuitive knowledge of their physical aspects.
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,
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.
Ocean in a Bottle
Source Institutions
In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.
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.
