1 1.1 What is Science? Mr. Doroski

2 What is Science? Science is an organized way gathering and analyzing evidence about the natural world.

3 What is Science? Technology is the application of science for practical purposes.

4 What is Science? The study of science is divided into two disciplines: 1.*Natural science 2.Social science

5 What is Science? *Natural Science is generally divided into three branches: I.~Physical science II.Earth and space science III.Life Science

6 What is Science? I.~Physical Science is the branch of science that focuses on matter and energy.

7 What is Science? Matter is a physical substance that has mass and takes up space.

8 What is Science? Energy is the capacity to do work.

9 What is Science? There are two main branches of physical science: A.Chemistry B.Physics

10 What is Science? A.Chemistry is the study of the composition, structure, properties, and reactions of matter.

11 What is Science? B.Physics is the study of matter and energy and the interactions between the two through forces and motion.

12 What is Science? **There are four “Big Ideas” within the study of physical science.

13 What is Science? Big Idea #1: – The universe is both very old and very big.

14 What is Science? – The age of the universe is about 13,700,000,000 (13.7 billion) years.

15 What is Science? – The observable universe is about 700,000,000,000,000,000,000,000,000 (700 million billion billion) meters in diameter.

16 What is Science? Big Idea #2: – All matter familiar on Earth is made up of building blocks called atoms.

17 What is Science? – Atoms consist of even smaller building blocks called electrons, protons, and neutrons.

18 What is Science? Big Idea #3: – Forces cause changes in motion.

19 What is Science? – If you push on something that is sitting still, it starts to move and if you push on something that is already moving, you will change its motion.

20 What is Science? Big Idea #4: – Energy can exist in six forms and it can be classified into two general types.

21 What is Science? The six forms that energy can take are: 1. Mechanical 2. Thermal 3. Chemical

22 What is Science? The forms of energy cont’: 4. Electrical 5. Electromagnetic 6. Nuclear

23 What is Science? The two types of energy that exist are: 1.Kinetic energy 2.Potential energy

24 What is Science? 1.Kinetic energy is the energy of motion.

25 What is Science? 2.Potential energy is the energy that is stored as a result of position or shape.
