Free-Fall Bottles & Tubes
Source Institutions
In this physics activity, learners conduct two experiments to explore free-falling.
Bubble Tray
Source Institutions
In this activity, learners use simple materials to create giant bubbles.
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.
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.
The Amazing Water Trick
Source Institutions
Using two baby food jars, food coloring, and an index card, you'll 'marry' the jars to see how hot water and cold water mix.
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.
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.
Eyedropper Hydrometer: Buoy your understanding of density
Source Institutions
Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.
Toast a Mole!
Source Institutions
In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!
Indicating Electrolysis
Source Institutions
Electrolysis is the breakdown of water into hydrogen and oxygen. This Exploratorium activity allows learners to visualize the process with an acid-based indicator.
Organ Pipe: Get Bach to the fundamentals
Source Institutions
If you got a big graduated or clear cylinder, water, a pipe, and a tuning fork, you've got a sound learning opportunity! Learn about resonance with this Exploratorium Science Snack.
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.
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.
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.
Geyser
Source Institutions
This Exploratorium activity can be used in many contexts because geysers are great opportunities for learning about heat and temperature changes as well as geological/space science phenomena.
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.
Make a Salt Volcano (Lava Lite)
Source Institutions
This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.
"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.
