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.
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).
When is a Glass of Water Really Full?
Source Institutions
In this activity, learners see how many coins they can add to a full glass of water before the water overflows.
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!
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.
Aluminum Boats
Source Institutions
Test the buoyancy of an aluminum foil boat and an aluminum foil ball. Why does the same material in different shapes sink or float?
Exploring Products: Nano Fabrics
Source Institutions
In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.
Make Your Own Deep-Sea Vent
Source Institutions
In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.
Let's Go Ice Fishing
Source Institutions
In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.
Be A Pasta Food Scientist
Source Institutions
In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.
Marshmallow Models
Source Institutions
No glue is needed for learners of any age to become marshmallow architects or engineers.
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.
Shrinking Cups
Source Institutions
This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.
Drops on a Penny
Source Institutions
In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.
The Incredible Journey
Source Institutions
In this weather activity (page 4 of the PDF), learners will explore the water cycle through an interactive game.
Oil Spill Cleanup
This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.
Walk On Water Bugs
Source Institutions
In this activity (on pages 29-35), learners examine water pollution and filtration.
Crystal Creations: Grow Spikes of Crystals in the Sun
Source Institutions
This activity shows you how to make amazing crystal spikes using Epsom salt and the sun.
Moisture Makers
Source Institutions
In this outdoor activity, learners compare the moisture released from different kinds of leaves and from different parts of the same leaf, by observing the color change of cobalt chloride paper.
