How do scientists conduct (do) and organize their studies?

• biology

• the scientific method

• observations

• hypothesis

Answer explanation

The scientific method is the series of steps scientists follow.

Scientists always begin by...

• communicating their results

• writing a hypothesis

• assembling their tools

• asking a question

Answer explanation

The scientific method begins with asking a question. Then, the scientist uses the steps of the scientific method to try to answer the question.

Before experimenting, you should make...

• observations.

• a model of your experiment.

• a chemical reaction.

• someome your lab assistant.

Answer explanation

You might be able to answer your questions by making observations, without doing an experiment at all.

What is a hypothesis?

• a bunsen burner

• a test tube

• an educated guess

• a lab coat

Answer explanation

A hypothesis is your theory about what the answer to the question is. If the results of your experiment are not what you expected according to your hypothesis, then the experiment has disproven your hypothesis, and you should come up with a new one, that you will also test.

To make sure your experiment shows you the usual (or typical) result, you should...

• start the experiment as soon as possible.

• wait a long time to conduct the experiment.

• do the experiment more than once.

• ask a classmate to watch you.

Answer explanation

If you only do the experiment once, you can't be sure that your results are representative of what usually happens in nature. It's best to do the experiment as many times as you can, so that you get an accurate picture of what the result tends to be (and you can be reasonably sure that your results are not affected by a mistake or an unusual condition).
