1
The Scientific Method Area 1: Belief and Science
2
Lesson Aim To learn about the scientific method as a source of human understanding
3
Can you remember??? What experiments have you done in Science subjects since S1?
4
Magnesium
6
Does anyone know where the word science comes from?
7
Science: Context Science is from the Latin “scientia”, which simply means knowledge
8
Science: Context Science is from the Latin “scientia”, which means knowledge The scientific method was first developed by Francis Bacon in the 17 th Century
9
Francis Bacon This outfit is nothing compared to my curtains
10
In his writings he proposed a theory of scientific knowledge based on observation and experiment that came to be known as the inductive method.
11
The Inductive Method The inductive method (also known as induction) is a type of reasoning that involves moving from a set of specific facts to a general conclusion.
12
The Inductive Method The inductive method (also known as induction) is a type of reasoning that involves moving from a set of specific facts to a general conclusion....for example...
13
The Inductive Method in Action 100 Dumbarton Academy pupils burned magnesium in a science experiment and it burned brightly. Therefore, all magnesium burns brightly
14
The Inductive Method in Action All ice I have ever touched has been cold. Therefore all ice is cold
15
The Inductive Method in Action One hundred snooker balls were struck with a cue, all of them moved. Therefore all snooker balls will move when struck with a cue

19
He demanded a planned procedure of investigating all things natural Francis Bacon is considered to be the pioneer of what is known as the scientific method He had a religious faith but never felt there was a clash between science and religion
20
So what exactly is this scientific method?

22
The Scientific Method 1.Observation 2.Hypothesis 3.Experiment 4.Deduction 5.Verification The 5 Stages Look familiar??
23
Stage 1: Observation Stage 1 begins with finding something in nature that you want to find an answer to. Observation involves collecting information and data
24
Stage 2: Hypothesis Stage 2 involves making an educated guess as to what may happen with your observations. A hypothesis is when you 'predict' what may happen
25
Stage 3: Experiment Stage 3 is to have a controlled experiment which will put your hypothesis to the test
26
Stage 4: Deduction Stage 4 involves making an informed judgement based on the results of your experiment. The hypothesis is reviewed and a theory is developed
27
Stage 5: Verification In Stage 5, the results from the experiment may support the hypothesis, which then becomes verified. Or your hypothesis is proved to be false, in which case you start again.
28
Stage 5: Verification Verification: confirmed as accurate or true by acceptable evidence Falsification: to disprove a theory

Science: Further Info Science cannot provide certain (100%) proof – just the ‘best’ working theories based on the evidence that we have
31
Science: Further Info Science cannot provide certain (100%) proof – just the ‘best’ working theories based on the evidence that we have It is a trial and error process
32
Science: Further Info Science cannot provide certain (100%) proof – just the ‘best’ working theories based on the evidence that we have It is a trial and error process Science allows us to systematically examine the processes behind the natural world, and make predictions and laws regarding these.

Science is a method used to understand the world, not a mountain of ‘facts’
