Question 1

What is Science?

Answer 1

Science is a way of understanding the world.

Question 2

Science Research

Answer 2

Science research allows us to extend our understanding.

Question 3

Applied Science

Answer 3

Applied Science allows us to use our understanding.

Question 4

Science has limitations. Science cannot consider…

Answer 4

1. Things that cannot be tested
2. Philosophical questions
3. Religious questions
4. Social questions

Question 5

Science uses several methods to reach understanding…

Answer 5

… the findings from each method must support each other before understanding is considered sound.

Examples are;

• Observation (many situations and scales)
• Experimentation
• Logical theoretical reasoning
• Mathematical reasoning

Question 6

Scientific literacy helps students to…

Answer 6

1. Be interested in and understand the world around them.
2. To engage in the discourses of and about science.
3. To be sceptical and questioning of claims made by others about scientific matters.
4. To be able to identify questions, investigate and draw evidence-based conclusions.
5. To make informed decisions about the environment and their own health and well-being.

Question 7

What is the first step in Science Inquiry?

Answer 7

Questioning and Predicting;

You identify the problem, identify the variables, and come up with a research question or hypothesis.

Question 8

What is the second step in Science Inquiry?

Answer 8

Planning and Conducting;

Operationalize variables. Plan the method, including the pre-trials. Carry out your experiment, measure and record.

Question 9

What is the third step in Science Inquiry?

Answer 9

Processing and Analyzing,
organize and represent your data. Analyze the data and use your scientific knowledge to identify and explain patterns and trends.

Question 10

What is the fourth step in Science Inquiry?

Answer 10

Evaluating.
Evaluate your findings in relation to the problem or question – remember, the findings from all methods used must support each other. Evaluate the design.

Question 11

What is the fifth and final step in Science Inquiry?

Answer 11

Communicating,

communicate your findings using scientific language and representation.

Question 12

What does literacies of science refer to?

Answer 12

Scientists use specific forms of language and literacy to learn about, represent and communicate their findings. They use things such as:

Data charts and tables
Graphs
Diagrams
Text
Headings
Measurements and Units of Measurement
Numbers

These are literacies of science.

Question 13

Control variables

Answer 13

these are variables that stay the same.

Question 14

Independent variable

Answer 14

is a variable that was deliberately changed. It can cause a change in the dependent variable, but the dependent variable can not change it.

Question 15

Dependent variable

Answer 15

may change as a result of the manipulation.

Question 16

Force

Answer 16

A force is a push or a pull on an object that results from an object interacting with another

Question 17

Force is equal to

Answer 17

mass (kgs) x acceleration (m/s2)

Question 18

Force is measured in

Answer 18

Newtons which is abbreviated as N

Question 19

Contact forces

Answer 19

are those that result when two interacting are perceived to be physically contacting each other; basically, this is a force caused by two objects that are touching; an example of this is friction.

Question 20

Action-at-a-distance forces

Answer 20

are the type of forces that result even when two interacting objects are not in physical contact with one another, yet are able to exert a push or pull despite their physical separation. Gravitational forces are an example of Action-at-a-distance forces.
