1.1 What is Science
 Science is a system of knowledge and the methods you use to find
that knowledge.
 Science begins with curiosity and often ends with discovery.
Science and Technology
Technology is the used of knowledge to solve a particular
problems.
Goal of science = expand knowledge
Goal of technology = apply the knowledge
Science and technology are interdependent. Advances
in one lead to advances in the other.
Advances in technology – The Telephone

 Two examples of the big idea should be on the poster. Each example should include a
description and a picture. Each example should be a real life example. (6 points per
example; 2 points for description, 2 points for visual, 1 point for neatness and 1 point for
grammar and spelling)

1.1 Review
Answers to Do Now
1. The three major branches of natural science are physical science,
life science and earth and space science.
2. A. Physics: The study of matter and energy and the interactions
between the two through forces and motion.
B. Biology: The study of living things.
C. Geology: The study of the origin, history and structure of Earth
D. Chemistry: The study of the composition, structure, properties,
and reactions of matter.
E. Astronomy: The study of the universe beyond Earth, including the
sun, moon, planets, and stars.
3. Science and technology are interdependent because as one advances
so does the other. An example of this is the evolution of the telephone. As
scientists learn more about how telephones work, upgrades were made
to the telephone.

Introduction – “Started with a Question”
Song
Started with a question now we here,
Started with a question now my whole class here (4x)
O?HEAC, tell-it one two (4x)
Explanation:
O = observations
?= Ask questions
H= Hypothesis
E = Experiment
A = Analyze data
C = Conclusion
Tell-it (1) write a report and (2) write a research paper
1.2 Using a Scientific Approach
What is the scientific method?
An organized plan for gathering, organizing, and
communicating information is called a scientific method.
The goal of any scientific method is to solve a problem or
to better understand an observed event.
Steps to a scientific method
1. Making observations (information you obtain through your senses)
2. Forming a Hypothesis (proposed answer to a question)
3. Experimenting (Testing a Hypothesis)
-(Independent) Manipulated variable: variable that causes a change in another;
The part of the experiment you can change.
-(Dependent) Responding variable: the variable the changes in response to the
manipulated variable.
*A controlled experiment is an experiment in which only one variable, the
manipulated variable, is deliberately changed at a time. While the responding
variable is observed for changes, all other variable are kept constant, or controlled.
For example:
If you increase the amount of water a plant receives, then
it will grow faster.
If you increase the amount of water and sunlight a plant
receives, then it will grow faster.
Information found in an hypothesis
 The (independent) manipulated variable is the part of the
experiment that you change.
 The (dependent) responding variable is the part of the experiment
in which you watch for its reaction to your changes.
Example:
“If I raise the temperature of a cup of water, then the amount of sugar
that can be dissolved in it will be increased.”
Identifying Variables: Whole Class Activity
 “If the water faucet is opened, then the amount of water flowing
will increase. ”
 “If a prisoner learns a work skill while in jail, then he is less likely to
commit a crime when he is released. ”
 “Drinking coffee makes people more anxious. “
4. Analyze data collection
5. Drawing Conclusions
-Conclusions are made based on the data collected.
-What happens if the data do not support the hypothesis?
(1) A scientist can revise the hypothesis or propose a new one based on the
data from the experiment.
(2) A new experiment must then be designed to test the revised or new
hypothesis.
6. Communicating Results (Tell-It!)
(1)Write a report
(2)Write a paper

Scientific Theory vs. Scientific Law
A scientific theory is a well-tested explanation for a set of observations
or experimental results.
-Theories are never proved. Instead, they become stronger if facts
continue to support them.
-However, if a theory fails to explain new facts and discoveries, it can
be replaced or revised.
Scientific law
 A statement that summarizes a pattern found in nature.
 A scientific law describes an observed pattern in nature without
attempting to explain it.
Example:
Working safely in Science
 Follow all safety precautions.
 Read all directions before you start any activity.
 Make sure you understand the entire procedure, especially any safety
precautions that must be followed.
 Single most important rule for your safety is simple: Always follow your teacher’s
instructions exactly. Ask questions if there is anything you do not understand.
