Investigating Density Currents
Source Institutions
In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).
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.
A Cubic Foot Per Second
Source Institutions
In this activity, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.
How Big is Small
Source Institutions
In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.
Pepper Scatter
Source Institutions
In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.
Under Pressure
Source Institutions
In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.
Using Solar Energy
Source Institutions
In this activity, learners discover how solar energy can be used to heat water.
Water Drop Races
Source Institutions
In this activity, learners will explore the physics of liquids and gas by playing with both! Learners of any age use their own breath to move drops of water across a smooth wax paper surface.
Make a "Mummy"
Source Institutions
The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.
Tie Dye Secret Messages
Source Institutions
In this activity, learners will write a secret message that only their friends will be able to read.
Solar Water Heater
Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.
Toast a Mole!
Source Institutions
In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!
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.
Indicating Electrolysis
Source Institutions
In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.
Exploring Products: Nano Fabrics
Source Institutions
In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.
Investigating Convection
Source Institutions
This experiment is designed to illustrate how fluids, including water, have the ability to flow.
Floating Paperclip and Other Surface Tension Experiments
Source Institutions
In this activity, learners experiment with surface tension using everyday household items such as strawberry baskets, paperclips, liquid dish soap, and pepper.
Electrostatic Water Attraction
Source Institutions
In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.
Build A Hydrometer
Source Institutions
In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.
"Boyle-ing" Water
Source Institutions
In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.
