Physical Science Week 2 Assessment Fourth Term

The first step in the scientific method is usually

• making an observation.

• forming a hypothesis.

• collecting data

• testing a hypothesis.

Scientific methods

• are a general description of scientific thinking.

• are used to find and evaluate possible answers to problems.

• use critical thinking to solve scientific problems.

• All of the above

Most scientific questions are developed from

• research.

• investigation.

• observations.

• forming a hypothesis.

After formulating a question, the next step of the scientific method is

• to research and collect data.

• to perform an experiment.

• to test a hypothesis.

• to state a conclusion.

Critical thinking

• is based on facts.

• uses logic

• uses observations.

• All of the above
