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.

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.

2-LS2-1 Plan and conduct an investigation to determine if plants need sunlight and water to grow.

The rattle on a Rattlesnake is an adaptation that:

  1. attracts a mate.

    No. Snakes do not hear airborne sounds, so another snake would not hear the rattle.
  2. attracts mice and other prey animals.

    No. Like other animals, mice would be frightened away by the rattle.
  3. warns predators to stay away.

    Yes! The sound of a Rattlesnake's rattle is a warning that the snake will bite to defend itself.
  4. helps the snake hide.

    No. There is nothing about the rattle that would serve as camouflage or help the snake hide.

Which position would the Moon be in during an eclipse of the Sun?

  1. A

    No. In this position, the Earth would not be in the Moon's shadow.
  2. B

    Yes! Solar eclipses only happen during a new moon, but even then, the alignment has to be just right for the Moon's shadow to fall on the Earth.
  3. C

    No. In this position, the Earth would not be in the Moon's shadow.
  4. D

    No. In this position, the Earth would not be in the Moon's shadow. You might get a lunar eclipse in this position, but not a solar eclipse.

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.

This baby praying mantis looks very much like its mother, but not exactly. What does that tell us about its life cycle?

  1. It does not undergo metamorphosis.

    No. While it does look similar to its parents, it lacks wings and other features which it will have as an adult.
  2. It has incomplete metamorphosis.

    Yes! It has most of the features of an adult, and will gain the final adult features later in its life.
  3. It has complete metamorphosis.

    No. For complete metamorphosis, the larva looks very different from the parent.
  4. It skipped metamorphosis.

    No. While it does look similar to its parents, it lacks wings and other features which it will have as an adult.
