We often talk about global warming. Do you know how does global warming happens? This experiment (实验) helps you learn how a greenhouse works, and how greenhouse gases influence the earth’s atmosphere.

What You Need:

·Two thermometers

·A notebook

·A pencil or pen

·A clear bottle

·A watch or clock

·A sunny area

What You Do:

(1)Put the thermometers in direct sunlight. Let them sit in the sun for three minutes.

(2)Draw two columns (栏), “Thermometer A” and “Thermometer B”, in the notebook.

(3)After the three minutes, read and record the time and temperatures in the notebook.

(4) Place one of the thermometers in the bottle and close it.

(5)Record the temperatures of the thermometers every ten minutes.

(6)Discuss how the bottle influences the temperature.

What’s Going On?

The temperature outside the bottle is changing, as the warm air mixes with the passing cooler air. The air inside the bottle can’t mix with the air outside—it just gets warmer as the sunlight heats it up. A greenhouse works in a similar way: sunlight creates heat that can’t get out of the glass.

1. What do you need in the experiment?

A．A dark room.

B．A paper box.

C．Some water.

D．Two thermometers.

2. How often do you record the temperatures of the thermometers?
