Drop Shape
Source Institutions
In this activity, learners get a closer look at the shape of a drop of water and a drop of oil. Learners first drip water onto wax paper and examine the shape of separate drops from a side view.
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.
The Liquid Rainbow
Source Institutions
Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.
Ice Melt
Source Institutions
In this activity, learners will explore basic information about thermodynamics by experimenting with ice. Learners will compare ice melting rates on metal pans or plastic cutting boards.
From Here to There
Source Institutions
In this water activity, learners discover ways to move water across the water table.
In the Toilet
Source Institutions
This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.
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.
Ice Cube Painting
Source Institutions
In this activity, learners "draw" with frozen tempera paint. The ice cubes are prepared the day before by placing watered down tempera paint and popsicle sticks in ice cube trays.
Convection Current
Source Institutions
In this activity, learners make their own heat waves in an aquarium.
Go With the Flow
Source Institutions
In this activity, learners will observe laminar and turbulent flow of water using only a plastic bottle, liquid hand soap, food coloring and water.
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.
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.
Outrageous Ooze: Is It a Liquid or a Solid?
Source Institutions
This activity provides instructions for using cornstarch and water to make an ooze which has the properties of both a solid and liquid.
Atoms and Matter (K-2)
Source Institutions
In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.
Soapy Boat
Source Institutions
Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.
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,
Magic Sand: Nanosurfaces
Source Institutions
This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).
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.
