What is more important, Imagination or Knowledge?
10
Taking Good Notes
How is it done?

• List key topics
• List any key words or definitions
• Use pictures and diagrams

11
Taking Good Notes
What should it be like?

• Needs to be organized HAVE A SYSTEM!!
• Needs to be neat AND readable
• Be concise and to the point

12
Note Taking Techniques
A. Listen for key words and clues

• Often repeated during lesson
• Unfamiliar or new words

B. Watch for things written down

• Items listed on overhead or board
• Diagrams or pictures pointed out

13
Taking Good Notes
C. When writing things down

• Use Roman Numeral Outline
• Use underlines for key words or definitions
• Use diagrams or pictures to help explain
• Re-copy your notes
• Use side margins for extra information

How to Solve a Problem!!

• The Scientific Method
• - a series of steps to help solve a problem

• Problem
• - ask a question or have problem to solve
• Hypothesis
• - a possible solution that can be tested

17
How to Solve a Problem!!
C. Develop an Experiment - test your
hypothesis What effects your experiment? Variables
factors that effect the results of an
experiment Controlled Experiments testing one
variable or factor at a time
18
How to Solve a Problem!!
1. Factors in a good experiment - has specific
procedure - can be duplicated by others -
able to determine an outcome
19
Scientific Models!
In your journal, explain what a model is, why it
is or is not important to use models, and what
are some examples of models.
20
How to Solve a Problem!!
D. Observations - What did you see happen
during the experiment - use your all your
senses - record what you observe! - Use graphs,
charts, pictures E. Analyze Results - what do
the observations say?
21
How to Solve a Problem!!
F. Draw Conclusions - did you prove your
hypothesis? - what could you do differently? G.
Communicate Results - Get Published! - Continue
to gather new evidence!
22
Scientific Models!
A Model is representation of a thing, object, or
idea it can be larger or smaller
23
The Big Question!
What is Life Science?
24
Scientific Models!

• Types of Models
• A. Physical Models looks like the actual
  thing. You can see it or hold it

25
Scientific Models!

• Types of Models
• B. Mathematical Models uses data or numbers to
  show ideas, concepts, or predications

26
Scientific Models!

• Types of Models
• C. Conceptual Models represent an idea of what
  might happen

27
Scientific Models!
II. Scientific Knowledge A. Theory explanation
of what happens based on hypothesis and
observations
28
Scientific Models!
B. Scientific Law a proven concept based on
experimentation
29
Challenge!

• Each group will get a Mr. Wilsons Pipe of
  Mystery.
• In your journal, sketch and describe what you
  see.
• Create a hypothesis on how the Pipe of Mystery
  works.
• Record your procedure and include both a written
  description and drawings of what you think is
  inside.

30
The Big Question!
What is technology? What is (if there is any)
advantage of technology?
31
Metric Measurement
To measure distance, use a meter stick unit of
measure is meters
Area length x width unit of measure is
squared

• Volume amount of space something takes up
• Solids length x width x height units cubed
  (cm3)
• Liquids use graduated cylinder (ml or cm3)

32
Metric Measurement
Mass amount of matter of an object measured in
grams triple-beam balance
Temperature how fast molecules are moving or
how hot or cold matter is Measured in Celsius
(Centigrade) 100º C boiling 37º C body
temperature 18º C room temp. 0º C freezing
33
The Big Question!
Why do you think scientists use tools such as
graduated cylinders and stopwatches?
