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.
Cartesian Diver
Source Institutions
In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.
Splitting White Light
Source Institutions
In this optics activity, learners split white light into all its component colors using three household items: a compact disc, dishwashing liquid, and a hose (outside).
Cellular Soap Opera
Source Institutions
In this activity, learners create a large film of soap and experiment with what can and cannot pass through it.
Changing the Density of an Object: Adding Material
Source Institutions
Learners see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float.
Formation of a Precipitate
Source Institutions
Learners create hard water by mixing Epsom salt and water. Then they compare what happens when soap solution is mixed with hard water and regular water.
Chew that Gum
Source Institutions
In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.
Cartesian Diver
Source Institutions
In this quick activity (page 1 of the PDF under SciGirls Activity: California Fish), learners will build a simple Cartesian Diver in an empty 2-liter bottle.
Soda Geyser
Source Institutions
In this quick activity (page 1 of PDF under SciGirls Activity: Lift Off), learners will use the ever-popular soda geyser experiment to test the reactivity of the various sugar candies or mints.
Erupting Fizz
Source Institutions
This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.
Tempest in a Teacup
Source Institutions
In this hands-on activity, learners determine the types of chemical reactions achieved when combining different household products.
Potion Commotion
Source Institutions
In this hands-on science experiment, students combine their understanding of the different states of matter and the characteristics of various chemical reactions.
Fill 'er Up!
Source Institutions
Learners discover that their breath contains carbon dioxide, one of the pollutants found in car exhaust.
Production of a Gas: Controlling a Chemical Reaction
Source Institutions
Learners mix vinegar and baking soda to produce a gas. With the addition of a bit of liquid soap, the gas becomes trapped in measurable bubbles.
Avogadro's Bubbly Adventure
Source Institutions
In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.
