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.

Why does this grasshopper have such small wings?

  1. Because this species does not fly.

    No. This species of grasshopper does fly.
  2. Because it has a mutation.

    No. This is a normal grasshopper, not a mutant.
  3. Because it is a cricket, not a grasshopper.

    No. This is a grasshopper.
  4. Because it is not an adult.

    Yes! Grasshoppers have incomplete metamorphosis. The immature grasshoppers look similar to adults, but have some differences. The immature stages of the grasshopper has small wings, but the adult stage has large, functional wings.

UT.5.V.1.c Compare various examples of offspring that do not initially resemble the parent organism but mature to become similar to the parent organism (e.g., mealworms and darkling beetles, tadpoles and frogs, seedlings and vegetables, caterpillars and butterflies).

NGSS


1-LS3-1 Make observations to construct an evidence-based account that young plants and animals are like, but not exactly like, their parents.

3-LS1-1 Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death.

A lightning bolt has a huge amount of energy. Which of these kinds of energy is NOT a major component of lightning?

  1. Heat

    No. A lightning bolt can heat the air to over 30,000 °C (54,000 °F)
  2. Electrical

    No. A lightning bolt has a tremendous amount of electrical energy, often several hundred million volts, and several hundred thousand amperes.
  3. Sound

    No. Thunder, the sound energy produced by a lightning bolt, is so loud that it can often be heard up to ten miles away.
  4. Chemical

    Yes. While a lightning bolt can cause chemical changes, very little of the bolt's energy is converted to chemical energy.

SC.3.P.10.1 Observe and describe some basic forms of energy, including light, heat, sound, electrical, and the energy of motion.

SC.4.P.10.1 Observe and describe some basic forms of energy, including light, heat, sound, electrical, and the energy of motion.

NGSS


4-PS3-2 Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.

I poured some water on this rock. Later that day, the water was all gone. What happened to it?

  1. It evaporated.

    Yes. When liquid water turns into water vapor, the process is called evaporation. That is what happened to the water on the rock.
  2. It sublimated.

    No. Sublimation is when a solid turns directly into a gas. Dry ice (frozen carbon dioxide) is an example of sublimation. The solid changes directly into carbon dioxide gas, without becoming a liquid.
  3. It condensed.

    No. Condensation is when a gas turns into a liquid. The drops of water that form on the outside of a glass of ice is the result of condensation.
  4. It precipitated.

    No. In weather, precipitation is when solid or liquid water falls from the clouds. Rain, snow, and sleet are examples of precipitation.

SC.3.P.9.1 Describe the changes water undergoes when it changes state through heating and cooling by using familiar scientific terms such as melting, freezing, boiling, evaporation, and condensation.

SC.5.E.7.1 Create a model to explain the parts of the water cycle. Water can be a gas, a liquid, or a solid and can go back and forth from one state to another.

None of these layers have been turned upside down. Based on the Law of Superposition, which layer is the oldest?

  1. A

    No. Layer A is on top of layer B, so it is younger than layer B. That means that it is not the oldest.
  2. B

    No. If you look at layer B, it is on top of layer C, which means that it is younger than layer C. B is not the oldest.
  3. C

    No. Look closely at the top part of layer C. The top part of layer C is on top of part of layer D. That tells us that layer C is younger than layer D.
  4. D

    Yes! This one is a bit tricky, because of the way the rocks were formed. Layer D formed first, as a flat, horizontal layer. Erosion weathered the left part of D away, forming a sloping hillside. Image the photo with layers A, B, and C erased, and it looks like a sloping hillside.

    Next, a nearby volcano erupted, spewing out lots of volcanic ash. The ash covered the hillside, forming layer C.

    Next, lava from the volcano flowed down over the ash, forming layer B.

    Later, the volcano erupted again, depositing another layer of volcanic ash to form layer A. After that, layer A was covered by another layer of lava, and then another layer of volcanic ash.

    So A is the youngest, followed by B, then C, and D is the oldest.

Which organ produces insulin to control blood sugar levels?

  1. Liver

    No. The liver produces bile, which digests fats.
  2. Gall Bladder

    No. The gall bladder stores the bile produced by the liver.
  3. Pancreas

    Yes! The pancreas produces insulin.
  4. Thyroid

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