Temperature Differences

The video tutorial explores how sunlight affects Earth's surface by conducting a lab experiment. Students create two mini environments using soil, sand, and rocks, and measure their temperatures. One environment is shaded to simulate cloud cover, while the other is exposed to a lamp representing sunlight. After 10 minutes, the temperature in the sunny environment rises more than in the shaded one. The experiment concludes that sunlight significantly warms surfaces, while shaded areas experience less heating.

What are some of the materials found on Earth's surface that are affected by sunlight?

• Concrete and asphalt

• Glass and rubber

• Soil, sand, and rocks

• Plastic and metal

In the lab setup, what is used to simulate sunlight?

• Candles

• Flashlights

• Lamps

• Mirrors

What is the purpose of covering one mini habitat with a piece of cloth in the experiment?

• To simulate rain

• To mimic cloud cover

• To block sound

• To create a wind effect

What was the temperature change observed in the shaded mini habitat after 10 minutes?

• It increased slightly

• It remained the same

• It increased significantly

• It decreased significantly

What conclusion can be drawn about the effect of sunlight on shaded surfaces?

• Shaded surfaces have no temperature change

• Shaded surfaces cool down faster

• Shaded surfaces are not heated as much as unshaded ones

• Shaded surfaces are heated more than unshaded ones
