What is the first step in the scientific method?

• Drawing a conclusion

• Forming a hypothesis

• Making an observation

• Conducting an experiment

Why is the scientific method considered iterative?

• Because it allows for repeated testing and modification of hypotheses

• Because it only involves one experiment

• Because it always follows a strict sequence of steps

• Because it never reaches a conclusion

What is an experimental variable?

• A variable that is not measured

• A variable that is changed to test its effects

• A variable that is kept constant

• A variable that is always the same in all experiments

What is the purpose of a control group in an experiment?

• To ensure the experiment is biased

• To change the experimental variable

• To compare results with the experimental group

• To introduce new variables

What system of units is used internationally in science?

• Customary System

• International System of Units (SI)

• Metric System

• Imperial System

Why is the SI system preferred in scientific measurements?

• It is easier to calculate and consistent

• It has fewer units

• It is more complex

• It is used only in the United States

What is a base unit in the SI system?

• A unit used for various basic measurements

• A unit that is always larger than other units

• A unit that is not used in science

• A unit used for length only

Which of the following is a base unit for temperature in the SI system?

• Rankine

• Kelvin

• Fahrenheit

• Celsius
