What is Science and Technology?

What is Science?

• Science is the knowing or the explaining of events in the real world.

• Science explains these events by using the scientific method.

• Science provides lots of scientific facts about the natural world.

• Examples of scientific facts: water is a liquid, a desk is a solid, etc.

The goals of Science

• Science has 3 goals: 1. Speak of only the real (natural) world.

2. Observe and organize information.

3. Provide explanations of events that we can test regularly for validity.

Types of Science

• There are several types of Science at work all over the world.

Scientists

• People that make scientific discoveries are called scientists.

The process of Scientific Discovery

• Scientific discoveries and explanations are made by using the analytical strategy called the scientific method

• The scientific method is used by all scientists worldwide.

Practice using the Scientific Method

• Investigate the following online activities involving the scientific method:

• Scientific Method In Action

• Scientific Method Word Problems

• Scientific Method

Cause and Effect

• We apply the scientific method in order to establish a « cause and effect » relationships in nature. (cause and effect)

A scientific law

• A scientific law is a pattern or an event that always repeats itself in the real world but we are not able to explain how or why it works.

• An example of a scientific law: the law of gravity

A scientific theory

• A scientific theory is a scientific model that explains the cause of an event that occurs in the real (natural) world.

• A scientific theory can be correct now but not correct in the future if we receive contradictory observations from testing the theory.

• An example of a scientific theory: the Big Bang Theory

Important scientific laws and theories

• Every person on Earth should have a general understanding of these 10 really important scientific laws and theories (in Mr. Hanrahan’s opinion)

Technology

• Technology is applying scientific facts in order to simplify our daily lives.

• Examples of technology: eye glasses, a desk, a pencil, a pen, clothing, etc.

Measurement of Matter

• Measurement is finding a number that shows the size or the amount of something.

The Metric System

• The metric system is a measurement system based upon multiples of 10.

• The word « metric » comes from the greek word metron that means « to measure ».

• Canadians use the metric system.

Converting into various units of measurement

• From time to time, it is necessary to convert from one unit type to another.

• This task is not easy because the math calculations can be quite complex and tedious.

• So, scientific calculators and the Internet can help us with these chores.
