Hot Stuff!: Investigation #4
Learners test two jars containing soil, one covered and one open, for changes in temperature. After placing the jars in the Sun, learners discover that the covered jar cools down more slowly.
Hot Stuff!: Investigation #1
Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.
Shell Shifts
Source Institutions
Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.
What's In Your Breath?
Source Institutions
In this activity, learners test to see if carbon dioxide is present in the air we breathe in and out by using a detector made from red cabbage.
Temperature Affects the Solubility of Gases
Source Institutions
In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.
Hot Stuff!: Investigation #2
Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.
Breathing Blue
Source Institutions
In this activity, learners test exhaled breath for carbon dioxide and learn how to use an indicator as a simple way to measure pH.
Making Naked Eggs: Eggs Without Shells
Source Institutions
This is an activity about acid-base reactions using eggs and vinegar. Learners place eggs inside a container of vinegar and leave to soak overnight.
Hot Stuff!: Investigation #3
Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.
Solving Dissolving
Source Institutions
The Sacred Cenote at Chichén Itzá is a sink hole, or well, containing groundwater. In this activity, learners create their own cenote using chalk, limestone, acids, and rain water.
"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.
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.
