Sunlight enters the Earth's atmosphere, passingthrough the blanket of greenhouse gases. As it

reaches the Earth's surface, land, water, andbiosphere absorb the sunlights energy. Onceabsorbed, this energy is sent back into theatmosphere. Some of the energy passes back intospace, but much of it remains trapped in the

atmosphere by the greenhouse gases, causing ourworld to heat up.

The greenhouse effect is the rise intemperature that the Earth experiences

because certain gases in the atmosphere(water vapour, carbon dioxide, nitrousoxide, and methane, for example) trapenergy from the sun.

The glass panels of the greenhouse let in

light but keep heat from escaping if the greenhouse effect becomes stronger,

it could make the Earth warmer than usual.Even a little extra warming may causeproblems for humans, plants, and animals.

EMPOWERMaterials:

1 Jar or other see-through containerData logger with heat sensor

Sunlamp or access to a sunny areato perform the experiment

Instructions 1) Place the both heat sensor in the sunlight for a few minutes to

let them get warm. 2) Record the readings of the sensor at the top of the columns of

the table as initial temperature. 3) Record the time next to the starting temperatures and place the

jar over the 1 of the sensor. The other sensor was act as control.

4) Every minute, record the readings of both thermometerswithout disturbing them.
