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.

The Earth stays in orbit around the Sun because:

  1. The Sun's gravity pulls on the Earth

    This is only part of the answer.
  2. The Earth's gravity pulls on the Sun

    This is only part of the answer.
  3. The gravity of the Sun and the Earth pull on each other

    Yes! The gravitational attraction between the Earth and the Sun is a result of both the Sun pulling on the Earth and the Earth pulling on the Sun.
  4. Gravity does not keep the Earth in its orbit.

    No. Without the pull of gravity, the Earth would continue moving in a straight path instead of curving around the Sun.

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.

From our new home in Utah, the stars are so bright that we can even see the Milky Way Galaxy. How far is the Milky Way Galaxy from Earth?

  1. 923 light years.

  2. 92.3 light years.

  3. 9.23 light years.

  4. We are in the Milky Way Galaxy.

Think about it, and when you think you know the answer, then continue.

The Sun and you and me and all the stars that we can see are in the galaxy we call the Milky Way.

Baking a cake is an example of:

  1. A physical change

    Partly right. Some of the changes involved in baking a cake are physical changes.
  2. A chemical change

    Partly right. Some of the changes involved in baking a cake are chemical changes.
  3. Both

    Yes! The process of baking a cake involves many changes. Some, such as water evaporating and sugar melting are physical changes. Others, such as baking powder reacting cause a change in the chemical formulas, indicating a chemical change. For more on this, read Changing How We Look at Changing
  4. Neither

    No. There are many changes involved in baking a cake.
