Q

Why can’t science answer questions with certainty?

A

Any answer to a scientific question is uncertain because people will never know everything about the world around them.

With new knowledge some old explanations no longer fit new information.

Q

What would be the independent variable in an experiment investigating the effect of weight on the speed of the vehicles?

A

The independent variable could be a vehicle pulling different weights at a certain speed.

The independent variable could be different vehicles pulling the same weight at the same speed.

16
Q

Why is it important to have a controlled group in an experiment?

A

A control group allows scientists to determine whether changes observed are due to the dependent variable or do to some other factor.

17
Q

What is an attempt to explain a pattern observed repeatedly in the natural world?

A

A scientific theory

A theory is not a guess! It is the result of supported observations resulting from several investigations.

18
Q

What is a rule that describes a pattern in nature?

A

A scientific law

19
Q

How are scientific theory and scientific law different?

A

Scientific theory attempts to explain why something happens the way it does.

Scientific law does not attempt to explain why something is happening. It simply describes a pattern.

20
Q

All objects exert gravitational force. Is this a scientific theory or a scientific law?

A

This is a scientific law because it does not explain why an observation is happening. It only describes a pattern.

21
Q

What is the practical use of science or applied science?

A

Technology

this is how humans adapt nature to meet needs and wants. Example: computer, telephone, the wheel

22
Q

Science and technology differ?

A

Science is the study of the natural world.

Technology is how we use the natural world to meet our needs or wants.

23
Q

How do scientists learn more about the natural world?

A

Scientists learn more about the natural world by making models, conducting experiments, and doing field studies.

24
Q

What are the three branches of science?

A

Life science, Earth science, and physical science

25
Q

What is life science?

A

Life science is the study of living things, plants, animals, where they live and how they interact.

26
Q

What is Earth science?

A

Earth science is the study of rocks, soil, oceans, black holes, clouds, rivers, planets, or the atmosphere. It also includes the study of weather and climate systems that affect the Earth.

27
Q

What is physical science?

A

Physical science is the study of matter and energy.

Matter is anything that takes up space and has mass.

The ability to cause change in matter is energy.
