The Nature of Science- Part 1

Scientists can communicate their results

• at scientific meetings

• in scientific journals

• by exchanging information on the internet

• all of the above

The part of an experiment in which all conditions are kept the same is the

• hypothesis

• control

• conclusion

• independent variable

The steps commonly used by scientists in gathering information to test hypotheses and solve problems are called

• descriptive research

• pure science

• scientific methods

• applied science

Which of these questions could not be answered with an investigation?

• What plants grow best in this climate?

• What fruit tastes the best?

• How much water does an apple tree need?

• What plants grow well in the shade?

You want to conduct an experiment about plants in your classroom. What would be your first step?

• Gather materials.

• Observe the plant.

• Ask a question.

• Analyze results.

How is this data being recorded?

• in a map

• in a chart

• in a picture

• in a bar graph

When you plan a scientific investigation, what is the best way to record the procedure you follow?

• Write down a few quick notes.

• Remember the procedure, but do not write it down so others cannot copy you.

• Write out a porcedure but keep it to yourself.

• Write out the procedure, so someone else can follow it.

Which of the following is an observation of the picture?

• The person is wearing a T-shirt
• It is a sunny day
• The person is going to a birthday party
• The gift is a DVD player

What is an inference?

• Just a random guess.

• When you try to explain observations.

• The same as an observation.

• no clue...

A scientist performs an experiment and asks other scientists around the world to replicate it.

Why would other scientists most likely try to perform the same experiment?

• to find out if weather of various regions of the world would affect the results

• to see if the experiment would be less expensive in another part of the world

• to confirm the results of the experiment conducted by the scientist

• to verify that the hypothesis of the experiment is a scientific law
