Test Your Science Knowledge

Here are some science questions to help you test your general science knowledge. They will also show you which of the Florida, Utah, and NGSS science standards each question is testing.

The questions are chosen randomly, so this quest will be different each time.

Would you rather see the most recently added questions?

Which part of your body comes closest to serving the same function as a flower?

  1. Sensory organs

    No. Plants can sense their surrounds just as well without flowers.
  2. Reproductive organs

    Yes! Flowers are the reproductive organs of the plant. While most animals are either male or female, most flowers have both male (stamen) and female (pistil) reproductive organs. In this photograph, the male stamens are the green stalks with the yellow ends. The female pistil is the white structure just below the stamens.
  3. Digestive system

    No. Plants make their own food, so they do not need a digestive system.
  4. Skeletal system

    No. The stiff cell wall of a plant cell serves the same function as our skeleton.

UT.7.IV.2.d Relate the structure of organs to an organism’s ability to survive in a specific environment (e.g., hollow bird bones allow them to fly in air, hollow structure of hair insulates animals from hot or cold, dense root structure allows plants to grow in compact soil, fish fins aid fish in moving in water).

Are the ocean waves crashing against this rock an example of:

  1. Erosion

    Partially right! This is an example of erosion. Sand and bits of the rock are being moved by the waves..
  2. Weathering

    Partially right! This is an example of weathering too. Weathering is when a rock is broken into smaller pieces. The waves and the sand they carry are slowly grinding away these rocks.

  3. Both erosion and weathering

    Yes! The rock is being broken into smaller pieces by the waves (weathering), and the pieces are also being carried away by the waves (erosion).
  4. Neither erosion nor weathering

    No. Both weathering and erosion are happening here.

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.

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.

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.
