This is called Obsidian. It is formed from molten lava that cools so quickly that it forms a natural glass instead of crystals. What kind of rock is it?.

  1. Igneous

    Yes! Igneous rocks formed from magma or lava. This is an igneous rock.
  2. Sedimentary

    No. Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. This is not a sedimentary rock.
  3. Metamorphic

    No. Metamorphic rocks have been changed by heat and pressure from a different kind of rock. Instead of being changed, this got hot enough to completely melt, so it is not metamorphic.
  4. Obsidian is not a rock.

    No. Obsidian is a naturally occurring solid that forms large layers in the Earth. Obsidian is a rock.

It takes the Earth 24 hours to:

  1. Rotate

    Yes. The Earth turns on its axis to make one full rotation every 24 hours.
  2. Revolve

    No. It takes a year for the Earth to revolve around the Sun.
  3. Orbit

    No. It takes a year for the Earth to orbit around the Sun.
  4. Reverse

    No. The motion of the Earth does not reverse.

Which organ produces bile to digest the fat in this bacon?

  1. Liver

    Yes! The liver produces bile, which digests fats.
  2. Gall Bladder

    No. The gall bladder stores the bile, but does not produce it.
  3. Pancreas

    No. The pancreas produces insulin to digest sugar.
  4. Thyroid

    No. The thyroid produces several hormones which control growth and metabolism, but it does not produce bile.

What do you have to do to replicate an experiment?

  1. You do the same experiment several times.

    No. Doing the same experiment several times is repetition, not replication.
  2. You do the same experiment that someone else did.

    Yes. By replicating an experiment exactly, you should get the same results as the original experiment.
  3. You do an improved version of someone's experiment.

    For replication, you do the experiment exactly as the original scientist did, without making any changes.
  4. You look for errors in someone's experiment.

    The purpose of replication is to verify, not to look for errors.

Which of the following is likely a sign that it will rain soon?

  1. Rising temperature

    No. A warm air mass moving into your area might bring rain, but it also might bring sunny weather. Rising temperature by itself is not a good indicator of rain.
  2. Decreasing humidity

    No. The humidity at ground level does not play much of a role in the formation of rain in the clouds. Just before it rains, the precipitation could cause the humidity to increase, but it would not cause it to decrease.
  3. Wind out of the west

    No. Any weather front moving in from the west could cause winds, even if it was bringing clear, sunny weather.
  4. Falling barometric pressure

    Yes! Low pressure fronts are commonly associated with rain and storms, so falling barometric pressure is a good indicator that rain may be on the way.
