Quest: 5th Grade, Nature of Science

Here are some science questions to help you test your knowledge of the Next Generation Sunshine State Standards.

The questions are chosen randomly, so this quest will be different each time you reload the page.

Back to the Grade 5 standards.



I used a Density Column to show that olives are denser than cherry tomatoes. To follow proper scientific procedure, the experiment needs to be checked by repetition and replication. What is the difference between repetition and replication?

  1. Repetition means that I do the same experiment again. Replication means that other people do exactly the same experiment again.

    Yes! To confirm your results it is important for you to repeat exactly the same experiment again (repetition) and then for other people to do exactly the same experiment again. (replication). If any of the results from repetition or replication are different from your original data, your original results are NOT confirmed, and you need to do more work.
  2. Repetition means that I do the same experiment again. Replication means that I do the experiment again after correcting errors.

    No. Replication is when other people to do exactly the same experiment.
  3. Repetition means that I do the same experiment again. Replication means that other people try to improve on my experiment.

    No. Replication is when other people to do exactly the same experiment.
  4. Repetition means that I do the experiment again after correcting errors.. Replication means that other people do exactly the same experiment again.

    No. Repetition means that I do the same experiment again.

3-5-ETS1-3 Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.

In the Yeast and Sugar video, I added different kinds of sugar to bottles with yeast and warm water. One of the bottles was a control. What should have been in that bottle?

  1. Just water

    No. With just water, you are removing two variables, the yeast and the sugar. You only want to remove the independent variable.
  2. Water and yeast

    Yes! A control should be exactly like the others, but without the independent variable (the variable you are changing in the experiment.) In this case, the variable you are changing is the kind of sugar, so the control should have everything except for the sugar.
  3. Water and sugar

    No. The yeast is not the independent variable, so leaving it out would not be correct.
  4. Water and salt

    No. Adding salt would be adding a new variable, which is not correct.

Which of the following observations is scientifically testable?

  1. Honeybees are good insects.

    No. "Good" is a generic term that could mean many different things in different situations. It is an opinion, not a testable property. This statement is NOT scientifically testable.
  2. Honeybees are important insects.

    No. "Important" is a generic term that could mean many different things to different people. It is an opinion, not a testable property. This statement is NOT scientifically testable.
  3. Honeybees are pretty insects.

    No. Some people might think that a honeybee is pretty, and some people might not. It is an opinion, not a testable property. This statement is NOT scientifically testable.
  4. Honeybees are not insects.

    Yes! While this statement is not correct, it is scientifically testable. You could examine the bee to see that it does fit the definition of an insect. This statement is IS scientifically testable.

SC.5.N.2.1 Recognize and explain that science is grounded in empirical observations that are testable; explanation must always be linked with evidence.

SC.8.N.2.1 Distinguish between scientific and pseudoscientific ideas.

Which of the following statements is scientifically testable?

  1. These alligators are scary.

    No. Being scary is not a physical property. Instead, it is an opinion. Some people might think they are scary, while other people might think they are not.
  2. These alligators have sharp teeth.

    Yes! Careful observation would show that all three of these alligators have very sharp teeth. Anyone who put their hand into the mouth of these alligators would find out quickly that sharp teeth are a measurable, physical property that is scientifically testable.

    Remember that scientifically testable properties are going to be the same, no matter who tests them. For example, these alligators each have four legs, scaly skin, and lungs for breathing air. They are carnivorous, which means that they eat other animals. They are reptiles, and they lay eggs.

    All of that information is based on physical evidence that can be checked and verified. You could count their legs, examine their skin, etc. These things are scientifically testable.

    On the other hand, opinions are a property of the observer, not the object. I may think alligators are interesting. Someone else may thing they are scary, or ugly, or boring. You could test different people, to see if they think alligators are scary, but you can't test the alligator to see if it is scary. Opinions are not scientific evidence about the object.

  3. These alligators have ugly eyes.

    No. Again, this is an opinion, not a measurable, physical property. I happen to think that alligators have pretty eyes.
  4. These alligators are lazy.

    No. Lazy is not a measurable property. I might call them lazy, but you might think that they are just waiting for something tasty to walk by. Lazy is an opinion, and is not scientifically testable.

Which of the following observations is NOT scientifically testable?

  1. Butterflies have pretty wings.

    Yes! Pretty is an opinion, and can vary from person to person, so it is NOT scientifically testable.
  2. Butterflies have six legs.

    No. This could be tested by counting the legs of a variety of butterflies.
  3. Butterflies can sting like bees.

    No. A claim does not have to be true to be testable. Examination of a variety of butterflies would show that they do not have stingers.
  4. Most butterflies drink nectar from flowers.

    No. This could be tested by observing the feeding habits of butterflies.

Explain more about it.

If I said that butterflies did not have six legs, you could show me physical evidence by counting their legs. After counting the legs, the physical evidence would show that butterflies have six legs.

If I said that I don't think butterfly wings are pretty, you could show me wings that you think are pretty, but I might not agree with your opinion. "Pretty" is not something that we can measure. What is pretty to one person might not be pretty to another, so it is not a testable property.
