HELP PLEASE You've learned that greenhouse gases, such as water vapor and carbon dioxide, absorb radiation given off by the warm earth. This causes the atmosphere to act like a blanket to warm Earth. The trapping of ground radiation (heat) by the earth's atmosphere is called the greenhouse effect. As an example of the atmosphere's greenhouse effect, the temperature doesn't drop as much on a cloudy night as it does on a clear night. In this investigation, you will create your own "greenhouse" to demonstrate the greenhouse effect.

OBJECTIVES

Demonstrate the greenhouse effect.

Relate your greenhouse to the global greenhouse effect.

Instructions

Watch the animation below and record your data on your paper.

01:1501:15

Draw a table on your piece of paper to record temperature readings for each box. You can use this template or a table similar to it:

Minutes Open box (In Sun) Greenhouse box (In Sun) Open box (No Sun) Greenhouse box (No Sun)

Once you have recorded all of your results, respond to the questions below. in which box did the temperature rise faster?in which box did the temperature rise higher? how did the temperatures in the boxes change after removing them from the sunlight? how does this experiment demonstrate the greenhouse effect ? what does each item used in the experiment represent in the actual greenhouse effect on earth? for instance, the light used in the experiment represents the sun. what does the bottom of the box, air in the box, and plastic wrap each represent in the greenhouse effect? if you can, compare your results with another student and explain the differences or similarities in your findings. what did you learn from this investigation?
