Clues About Clouds
Source Institutions
In this weather activity which requires adult supervision, learners will get a chance to make a cloud right here on Earth!
Collect Oxygen Over Water
Source Institutions
In this activity, learners use a pneumatic trough (see related activity) to generate and collect pure oxygen.
A Funny Taste
Source Institutions
In this activity, learners explore the different salinities of various sources of water by taste-testing.
Draft Detectives
Source Institutions
In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.
Find the Fizz: Discover the Secret of Baking Powder
Source Institutions
In this activity on page 4 of the PDF (Get Cooking With Chemistry), learners investigate ingredients that combine to produce gas bubbles.
Blowin’ Up a Storm of Oil
Source Institutions
In this activity, learners investigate how wind can create surface currents and how waves move. Learners also discover how wind can affect oil spills.
Jam Jar Jet
Source Institutions
In this activity, learners create a "Jam Jar Jet" based on Francois Reynst's discovery of a pulsejet engine, which uses one opening for both air intake and exhaust.
It's a Gas!
Source Institutions
In this simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.
Bready Bubble Balloon
Source Institutions
Learners discover the bubble power of living cells in this multi-hour experiment with baker's yeast. Learners make a living yeast/water solution in a bottle, and add table sugar to feed the yeast.
Atoms and Matter (3-6)
Source Institutions
In this activity, learners build models of atoms and molecules, then consider their role in different phases of matter, density, and mixtures and solutions.
Diet Light
Source Institutions
In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.
Inverse Functions: Pennies, Pressure, Temperature, and Light
Source Institutions
The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.
Sublime Sublimation
Source Institutions
In this activity, learners explore sublimation by conducting experiments with dry ice.
Divers
Source Institutions
Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.
How Can Gravity Make Something Go Up?
Source Institutions
In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.
Gas Production: Blow up a balloon!
Source Institutions
In this classic reaction, learners baking soda and vinegar in a soda bottle to produce carbon dioxide (CO2) gas. This gas inflates a balloon.
Soda Explosion
Source Institutions
This hands-on activity lets participant explore chemical reactions as they create a soda explosion with lots of bubbles. The bubbles in soda are made of carbon dioxide gas.
A Recipe for Air
Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.
Odors Aloft
Source Institutions
Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.
Dunking the Planets
Source Institutions
In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.
