This limestone is in Middle Tennessee, and contains a wide variety of fossils of ocean creatures. What kind of rock is limestone?

  1. Igneous

    No. Igneous rocks are formed from molten lava or magma.
  2. Sedimentary

    Yes! Sedimentary rocks are made up of bits of other rocks that have been deposited by wind, water, ice, or gravity. This limestone was deposited by the ocean, making it a sedimentary rock.
  3. Metamorphic

    No. Metamorphic rocks have been changed by heat and/or pressure. If this limestone was exposed to tremendous heat and pressure, it could change into a metamorphic rock called marble.
  4. Limestone is not a rock.

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

I found this caterpillar in my garden. Based on its bright colors, I decided not to pick it up. Why would it be so brightly colored?

  1. To help it hide in flowers.

    No. Its pattern of colors would not blend in with a flower.
  2. To warn away predators.

    Yes! Many brightly colored animals are toxic or dangerous. They use their bright colors to warn potential predators that they taste bad, sting, or have some other characteristic that a predator would want to avoid.

    This is the caterpillar of a Hooded Owlet Moth. They eat the wild asters in our area, which gives them a very bitter taste that birds don't like.

  3. To attract a mate.

    No. Caterpillars do not mate. They must go through metamorphosis into a butterfly or moth before they can mate.
  4. To help it find food.

    No. Most caterpillars eat plants, and bright colors would not help with that..

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.

This caterpillar is an example of which part of the food web?

  1. Producer.

    No. The plant is a producer. It captures energy from sunlight, and stores it as food. The caterpillar is eating the plant to get that energy.
  2. Primary Consumer.

    Yes! The caterpillar is eating the plant (a producer) to get the energy that is stored in its leaves.
  3. Secondary Consumer

    No. Secondary consumers eat other consumers. A bird that ate this caterpillar would be a secondary consumer.
  4. Decomposer

    No. Decomposers break down dead and decaying organisms. The plant that the caterpillar is eating is still alive and growing.

While this spoon appears to have a broken handle, it is just the result of how the water affects the light. This is an example of:

  1. Refraction

    Yes! Refraction bends light as it moves from one substance to another. As the light passes from the water to the air, its path is changed, making it appear that the spoon is broken.
  2. Reflection

    No. While some light is reflected from the glass, it is not responsible for the bending of the light.
  3. Absorption

    No. The water and glass are both clear, telling us that very little of the light is being absorbed. Absorption does not bend the light.
  4. Diffusion

    No. Diffusion is the scattering of light as it is reflected in many different directions. Diffusion would make the image cloudy and blurry.
