I put a paper plate on top of a glass of water. I turned it over, and the water stayed in the glass.

The weight of the water is pushing down on the paper plate, but the plate stays in the glass because the pull of gravity is being balanced by another force. What is that force?

  1. Attraction

    No. The slight attraction between the water and the glass is not enough to balance the pull of gravity.
  2. Air pressure

    Yes! Because the plate is keeping outside air from entering the glass, outside air pressure is keeping the plate in place. As long as the outside air pressure is enough to balance the weight of the water and the plate, it will stay in place. If you made a small hole in the glass to let outside air get in, that would unbalance things, and the water would fall out.
  3. Surface tension

    No. The water tension at the surface of the water would not balance the force of gravity.
  4. The weight of the paper card

    No. Gravity is pulling down on the paper plate and the water. The weight of the paper does not help balance the force of gravity.

How hot does an area have to be to be classified as a desert?

Answer:

Deserts are defined by lack of precipitation, not by temperature. They are areas where precipitation minus evaporation yields less than 10 inches of rain per year. The largest desert on Earth is in Antarctica, a very cold place.

I gave this balloon a negative electrostatic charge by rubbing it on my hair. Then I tore up bits of paper, and put them on the table. When I brought the balloon near them, they were attracted to the balloon. Why?

  1. The negative charge of the balloon induced a positive charge on the paper.

    Yes! The negative charge on the balloon pushes some of the negatively charged electrons in the paper to the far side, leaving the near side with a positive charge. Opposite charges attract, so the paper is attracted to the balloon.
  2. The negative charge of the balloon attracts the neutrally charged paper.

    No. As long as the paper is neutral, it will not be attracted or repelled.
  3. Tearing the paper gave it a positive charge.

    No. If the paper had a positive charge from being torn, the bits of paper with like charges would have repelled each other before you moved the balloon nearby.
  4. Paper is always attracted to balloons.

    No. This is easily tested by using a balloon that has not been rubbed on your hair. Without the positive charge, the paper is not attracted.

The light area on the left side of this photo is the Milky Way. What is the Milky Way?

  1. A constellation.

    No. The Milky Way contains many more stars than a constellation.
  2. A solar system.

    No. A solar system only has one star, not a huge number of stars.
  3. A galaxy.

    Yes! Our solar system is part of the Milky Way galaxy. When we lived in the city, the lights made it difficult to see the Milky Way. Now that we live far from city lights, it is amazingly easy to see.
  4. A universe.

    No. The Milky Way is only a small part of the entire universe.
