Classroom Guidelines
1.
2.
3.
Use Common Sense at all times
Do not give me any more gray hairs
Golden Rule
Other than that, you’re expected to follow
the school handbook guidelines and are
subject to consequences that match the
offense
Grading

Homework Policy

Content will be divided up into units with a
unit test

Labs will be conducted at least once per
unit
Participation Grade

Start with 100 points every quarter (9 wks)

Points subtracted for being out of class
 Unexcused
absence
 Tardy
 Restroom
use
 Excused absence
- 10 points
- 6 points
- 4 points
- 2 points
Sample of a unit grade

Can you pass this class?

Even if you completely fail the test with a
zero you can still have a 75% on the unit

The Semester final is worth 20% of your
semester grade. Each quarter is worth
40% of your semester grade.

The answer is most likely YES
Test Questions
(yes these will be on the final)
What is the goal of science?
1.
•
To gain knowledge about the world
Define “intelligence”
2.
•
Intelligence is the ability to learn from the
world
What is the absence of intelligence?
3.
•
Stupidity, which means the inability to learn
from one’s world or situation
What’s this class about?

Basically a two part course
Fall Semester: Chemistry
 Spring Semester: Physics


Basics of “Real” Science
Fall Semester: Chemistry
Scientific Method & Metric System
 Properties of Matter
 Atoms & Molecules
 Conversions
 Chemical Equations
 Chemical Reactions

Spring Semester: Physics
Measurement and Motion
 Newton’s Laws
 Work and Energy
 Simple Machines
 Electricity and Magnetism
 Waves

What is “Real” Science?
This course will be difficult because it will
challenge your reading, writing, and math
skills. It is one reason why it traditionally a
more challenging class.
Real science uses the principles of logic and
reasoning to gain knowledge about the
world around us.

the Metric System
Unit 1
The Scientific Method
(Organized common sense)
1.

3.
4.
5.
6.
State a question or problem
Gather background information
Formulate a hypothesis
Conduct an experiment
Gather Data
Write a conclusion
1. Question Statement
 Must
be specific
 Must
be testable
2. Background Information

Gathered in response to the initial
question

Is there an answer to the question in
someone else’s experiment?

Leads to the formation of the hypothesis
3. Hypothesis

“Educated Guess”

Based on information gathered in previous
experiments or researching

Must be tested in the experiment to see if
the “guess” was correct (its ok if you’re
wrong sometimes )
4. Experiment

Based on the initial question statement

Tests the hypothesis

Gives you data
5. Results

The “Data” section

No answers to the initial question are
given

Simply lists the results of the testing done
in the experiment
6. Conclusion

A written statement

Answers the initial question

Evaluates the hypothesis

Sometimes another question is asked and
the process starts all over!
The Metric System

Based on powers of 10

Base Units with prefixes identify the
magnitude (size) of the measurement

Find your question
Pick the correct conversion so that you
cancel out the unit you don’t want
Solve the problem
Example:
1,367 meters = km?
