WHAT IS SCIENCE? 6th Grade Life Science Blue Ridge Middle School Mrs. Bright
1. WHAT IS SCIENCE? • Science is the total collection of knowledge gained through man’s observation of the physical world. • Science is a process by which scientists learn about the world and solve problems. • Science is a way of learning more about the natural world.
2. The word ‘science’ comes from the Latin word “scire” which means … to know
3. What is the goal of science? • To explore, explain, and come to understand the world around us.
4. What questions CAN’T be answered by science? • Science can attempt to answer many questions about the natural world, but some questions cannot be answered by science. • Questions about art, politics, personal preference, or morality can’t be answered by science. • Science can’t tell you what is right, wrong, good, or bad.
Science can answer a question only with the information available at the time.
As new information becomes available, explanations can be modified or discarded and new explanations can be made.
5. What is the key method for obtaining scientific information (data)? • Observations • 1.Qualitative (describes) • 2. Quantitative (measures)
6. What is always involved in making a scientific observation? • One or more of your 5 senses.
7. What is a ‘fact’ • A truth about nature that can be verified. Alice is a girl. (fact) Alice is pretty. (opinion)
Jules Henri Poincare, a famous 19th century French scientist said, “Science is built up with FACTS, as a house is with stones. BUT a collection of facts is no more a science then a heap of stones is a house.
Understanding science is more than knowing facts. • Scientists organize data (facts) in a way that allow them to make connections between major ideas.
8. How do scientists use facts? • Scientists are like detectives. • Scientists use facts like clues to solve the larger mysteries of nature.
9.What are the 3 braches of science? • Science often is divided into three main categories, or branches—Life science, Earth science, and Physical science. • Each branch asks questions about different kinds of systems.
10. Define ‘life science’. • The study of living systems and the ways in which they interact is called life science. • Life scientists can study living organisms, where they live, and how they interact.
11. Name 3 careers that are part of life science. • People who work in the health field know a lot about the life sciences. • Some other examples of careers that use life science include biologists, zookeepers, botanists, farmers, and beekeepers.
12. Define ‘Earth science’. • The study of Earth systems and the systems in space is Earth science. • It includes the study of nonliving things such as rocks, soil, clouds, rivers, oceans, planets, stars, meteors, and black holes. • Earth science also covers the weather and climate systems that affect Earth.
13. Name 3 careers associated with Earth science. • Meteorologists study weather and climate. • Geologists study rocks and geologic features. • A volcanologist is a person who studies volcanoes.
14. Define ‘physical science’. • The study of matter and energy is physicalscience. • Matter is anything that takes up space and has mass. • The ability to cause change in matter is energy.
15. What are the 2 fields under physical science. • Physical science can be divided into two general fields—chemistry and physics. • Chemistry is the study of matter and the interactions of matter. • Physics is the study of energy and its ability to change matter.
16. Name 3 careers associated with physical science. • Many careers are based on the physical sciences. • Physicists and chemists are some obvious careers.
Ultrasound and X-ray technicians working in the medical field study physical science because they study the energy in ultrasound or X-rays and how it affects a living system.
17. Define ‘technology’. • Technology is the practical use of science, or applied science. • The study of how to use the energy of sunlight is science. Using this knowledge to create solar panels is technology. • The GOAL of technology is to make modifications in the world to meet human needs.
18. What is the difference between hypothesis, theory, & law? • A HYPOTHESIS is a prediction that can be tested. • A THEORY is an explanation based on scientific knowledge that is the result of many observations. • A LAW is a statement about how things work in nature that seems to be true all the time.
Section Check 1 Question 1 Studying how the sun makes energy is science. Putting this knowledge to use in making solar panels, however, is called _______. A. philosophy B. solar science C. technology D. the scientific method
Section Check 1 Answer The correct answer is C. The term “technology” refers to the application of knowledge gained through the use of science. For example, understanding why natural gas burns is science; a gas-burning stove is technology.
Section Check 1 Question 2 Which of the following questions cannot be answered by science? A. How old is the sun? B. How do volcanoes erupt? C. Should we be kind to strangers? D. Why is the sky blue?
Section Check 1 Answer The answer is C. Moral questions cannot be answered by science. The other questions can be answered by the careful study of nature.
