Transcript Chapter 1-Discovering Science 1. What is Science?

Chapter 1
What is Science?
• the study of nature and how it affects us
• a body of knowledge, constantly changing
through use of better and more accurate
tools for investigation
Study of Science includes
• Attitudes
• Process Skills
• Products
Some attitudes
important to the learning of science are
Curiosity
Perseverance
Positive approach to failure
Open-mindedness
Cooperation with others
Tolerance
Healthy scepticism
Integrity

The basic process skills are:
To use our senses to
obtain information
about objects, events
and changes
Observe
To find out the physical
properties (e.g. length,
area and mass) of matter
accurately with the help of
measuring instruments.
Measure
To transmit and receive
information presented in
various forms - verbal,
written, tabulated,
graphical or pictorial.
Communicate
To group objects or events
according to common
properties
Classify
To make an educated
guess of how things may
turn out based on previous
experience or knowledge.
Predict
To draw conclusions from
observations

• Carrying out
investigation
Which process skill is involved when:
(a) your friend says that your paper-bag will
tear when he sees you putting many cans
of food inside
(b) a teacher puts her pupils into different
Groups based on their height
(c) a person says that his dog is sick because it
is not its usual self
(d) someone draws and labels a diagram to
show you what a flower looks like when
cut
(e) someone tells you that he has prepared
something that is white and has a salty
taste
• Used by scientists
• Incorporates various science
process skills
The Scientific Method
Make careful observations or accurate measurements
Record the observations or measurements
Define a problem or state a clearly-worded question
Suggest a hypothesis (a possible explanation)
Design and carry out an experiment to find out whether hypothesis
is correct
If the experimental results
support the hypothesis,
it becomes a theory
do not support the hypothesis, reject it
and suggest a new hypothesis
If the theory is tested a number of times and is still
found to be true, the theory becomes a law of science
