section 1 what science is and is not
Section 1What Science is and is not.

The goal of science is to investigate and understand nature, to explain events in nature and to use those explanations to make useful predictions.

slide3

Science is an organized way of using evidence to learn about the natural world.

The word Science also refers to the body of knowledge that scientists have built up after years of using this process.

evidence based on observation
Evidence Based on Observation

Science starts with observation.

slide5

Observation involves using one or more of the senses: sight, hearing, touch, smell, and sometimes taste to gather information.

quantitative observation
Quantitative Observation

Quantitative Observations involve numbers.

An example of quantitative observation is “There are 4 sharks in the water!”

qualitative observation
Qualitative Observation

Qualitative Observations involve characteristics that cannot be easily measured or counted, such as color or texture.

A qualitative observation could be “That Great White shark has very rough skin!”

interpreting the evidence
Interpreting the Evidence

An observation alone has little meaning in science, because the goal is to understand what was observed.

slide11

An Inference is a logical interpretation based on prior knowledge and experience.

Example: researchers might sample water from a reservoir, if samples collected from different parts of the reservoir are all clean enough to drink, the researchers may Infer that all the water in the reservoir is safe to drink.

explaining the evidence
Explaining the Evidence

A Hypothesis is a possible explanation for a set of observations or an answer to a scientific question.

slide13

In everyday settings, a hypothesis can be stated about any topic or idea.

In science, a hypothesis is useful only if it can be tested.

slide15

Hypotheses may arise from prior knowledge, logical inferences, or imaginative guesses.

The testing may sometimes be done by making further observations or through careful questioning.

slide17

The tests of a hypothesis may support it, or suggest that the hypothesis is partly true but needs to be revised.

slide19

No matter what the outcome, a tested hypothesis has value in science because it helps researchers advance scientific knowledge.

What is the goal of science and why?

In everyday settings:

A hypothesis may arise from:

The tests of a hypothesis may:

The word science refers to:

a scientific view of the world
A Scientific View of the World

Scientists are persuaded by logical arguments that are supported by evidence.

slide23
For scientists, science is an ongoing process, not the discovery of an unchanging, absolute truth.
  • Scientific findings are always subject to revision as new evidence is developed.
slide24
Certain qualities are desirable in a scientist: Curiosity, honesty, openmindedness, skepticism, and the recognition that science has limits.
slide26

Science cannot help you answer moral questions.

Science cannot help you decide whether a painting is beautiful or cheating on a test is wrong.

Today, scientists contribute information to discussions about health and disease, and about the relationship between human beings and the rest of the living world.
