What is the greenhouse effect and how does it effect us? ?
Materials Shoebox Soil/ sand Two thermometers Colorless plastic food wrap/ glass Timer Hot light Camera
Steps of investigation First we took a shoebox and filled it with dirt. Then we covered the shoebox with colorless food wrap. Then we put one thermometer in the box and one out of the box. We started a timer and waited. Then we checked the temperatures at the end and wrote them down.
Results for First Experiment Heat source: Hot light Our Starting temperature for both of the thermometers was 15° C. The end temperature for the one inside the box was 24° C and the one out of the box was 22° C. The difference was 2° C.
Results for Other Hot Box Experiments Heat Source: Hot Light Cover: Plastic Material in box: Dirt Starting Temperature: 13° C End Temp. for in the box: 25° C End time: 30 min End temp. for out of the box:18° C Diff. 7˚ C ____________________________________________________________ Heat Source: Sun Cover: Glass Material in box: Sand Start temp: 15° CTemp. in box : 24° C Difference: 7° C Temp. out of box: 14° C ____________________________________________________________
Conclusions The temperature inside the box were always warmer then the temperature outside the box.
Related Topics The greenhouse affect happens when there are greenhouse gasses in the atmosphere. Greenhouse gasses are gasses that take in a little of the inferred radiation the earth gives off and warms the surrounding air. The inferred radiation comes from the sun. Life would not happen without the greenhouse effect. For example, the moon gets a lot cooler than any place on the earth ( -280°) and warmer (260°).
Related Topics (continued) The greenhouse effect is also a problem. Some scientists think that there are too many greenhouse gasses being emitted in to the atmosphere and that they causing global warming. Global warming is when the greenhouse effect heats up the world more than it is supposed to.
What we learned about God in our project God made the world so perfect that we can survive on it but we have to be careful.
