A Funny Taste
Source Institutions
In this activity, learners explore the different salinities of various sources of water by taste-testing.
Water, Water Everywhere
Source Institutions
In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea
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,
Earth's Water: A Drop in Your Cup
Source Institutions
This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour
Earth's Water: A Drop in Your Cup

This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour
Liquid Lens
Source Institutions
In this activity, learners discover that they can create a lens from a water drop. Learners test their lens by looking at words or pictures.
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 Causes Wind?
Source Institutions
In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.
Turbidity
Source Institutions
This is an activity about turbidity, or the amount of sediment suspended in water.
Does Size Make a Difference?
Source Institutions
In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.
Balloon Impacts
Source Institutions
In this activity, learners measure the diameter of their water balloons, model an impact, measure the diameter of the “crater” area, and determine the ratio of impactor to crater.
Mystery Sand
Source Institutions
In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.
Cooling the Mummy's Tomb
Source Institutions
In this activity, learners conduct an experiment to help Pharaoh design a better insulated tomb.
Temperature Affects Dissolving
Source Institutions
Learners design their own experiment to compare how well cocoa mix dissolves in cold and hot water. They will see that cocoa mix dissolves much better in hot water. Adult supervision recommended.
Look-alike Liquids
Source Institutions
Learners add drops of four liquids (water, alcohol, salt water, and detergent solution) to different surfaces and observe the liquids' behavior.
Cool It!
Source Institutions
In this fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!
Kid Moon: Splat!
Source Institutions
In this activity, learners model ancient lunar impacts using water balloons.
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.
Making An Impact!
Source Institutions
In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.
Mysterious M&M's
Source Institutions
Learners place an M&M candy in water and observe what happens. The sugar-and-color coating dissolves and spreads out in a circular pattern around the M&M.
