Some people think carbon dioxide levels in our atmosphere are too high. They are afraid the Earth's temperature will rise, making our lives less healthy. The World Resources Institute in Washington, D.C., says electric utility companies, industries, businesses, homes, and transportation are the major reasons that carbon dioxide levels build up in our atmosphere.
In this experiment , you will :
- Observe the effects of carbon dioxide gas.
- Test for the presence of carbon dioxide gas.
- Compare concentrations of carbon dioxide gas.
- Recognize that high levels of carbon dioxide gas are unhealthy to people & animals.
- Matches • Baking soda
- Vinegar • One Candle (that can stand on its own)
- A Drinking straw • A Round balloon
- Two clear narrow glasses or beakers
- A diluting (lowering) of the ocean's saline (salt) concentrations, which would threaten marine species,
- Flooding of coastal areas that border the oceans, where much of the world’s populations live.
Experiment : (1) Light the candle; (2) Mix vinegar and baking soda in a glass or beaker; (3) Tilt the glass or beaker over the burning candle.(Do not let the liquid run out). What happens? (4) Insert the straw into the neck of the balloon; (5) Mix vinegar and baking soda again; (6) Put the straw (attached to the balloon) in the space above the vinegar and baking soda. What happens this time?
What is the name of the gas that people and animals exhale?
What gas goes into the air/atmosphere when we run automobiles, fireplaces or power plants? Think of ways people can decrease the amount of carbon dioxide going into the air (without stopping breathing of course!!).
