Pine trees do not have flowers. What structure do they have that servers the same purpose?

  1. Needles

    No. Pine needles are a kind of leaf. They are not used for reproduction.
  2. Cones

    Yes! Pine cones produce pollen and seeds, just as flowers do in flowering plants.
  3. Fruit

    No. Fruit are used for dispersing seeds, not for pollination.
  4. Buds

    No. Pine tree buds produce needles. They are not involved in reproduction.

You have probably seen patterns of light like this in a pool of water. What causes it?

  1. Absorption

    No. If the light was being absorbed, the pattern would be dark instead of bright.
  2. Diffusion

    No. Diffusion is the scattering of light as it is reflected in many different directions. Diffusion would make the entire area brighter, not a specific pattern.
  3. Reflection

    No. While the light has to reflect back to your eye for you to see it, reflection does not cause this pattern.
  4. Refraction

    Yes! Refraction bends light. Waves and ripples on the surface of the water act just like the curved surface of a lens. This bends the light into patterns that have shapes similar to the ripples on the water's surface.

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.

These building stones are made of a rock called coquina. The rock is almost entirely made up of pieces of fossil sea shells. What kind of rock is it?

  1. Igneous

    No. Igneous rocks formed from magma or lava. That would have melted and destroyed the fossil shells. This is not an igneous rock.
  2. Sedimentary

    Yes! Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. These bits of shell were deposited by water, so coquina is a Sedimentary rock.
  3. Metamorphic

    No. Coquina has not been changed by heat and pressure from a different kind of rock, so it is not metamorphic.
  4. Coquina is not a rock.

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