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.
Float Your Boat
Source Institutions
In this physics activity, learners will explore buoyancy.
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.
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.
Build A Bee Bath
Source Institutions
In this activity, learners use found natural materials to create a water haven for bees and other insects.
The Rain Man
Source Institutions
In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.
Low-Tech Water Filter for High-Impact Clean
Source Institutions
In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.
Frozen Sculptures
Source Institutions
In this activity, learners use objects they find on a nature and water to make creative frozen sculptures.
Ocean Currents
Source Institutions
In this activity, learners will explore how density is affected by temperature and how that can create currents.
