1. Communication in Science
**Precise communication is crucial for scientists to share their results effectively with each other and society.**
Peer Review: Scientists in the same field verify each other’s results.
Ways that communication happens:
Lab Reports: Written accounts of investigations.

3. Objective
Students will be able to explain how scientists use graphs to communicate.
Students will be able to compare and contrast a scientific theory with a scientific law.

4. Word of the Day
Peer Review: When people in the same field verify each other’s work.

5. Communication in Science
Graphs: Visually demonstrate relationships among data sets
Graphs show trends in data (patterns.)
3 Main types:
Line:
X is independent variable. Y is dependent variable.
Y - axis
X - axis

Circle (Pie):
Bar Graph:
Represents a fixed quantity.
Circle = 100%
Slices = %tages of the whole.
Shows quantities 5 4 3 2 1

7. Communication in Science
Models - Scientific Model - an idea / picture map, system, or mathematical equation: E = mc
Models often change with new information.
Theories and Laws
Scientific Theory: An explanation based on many observations during repeated investigations.
Theories can be tested and they can be changed. - Not Proven.
Example: Theory of Relativity. 2

8. Communication in Science
Scientific Law: A principal that describes the behavior of a natural phenomenon.
Events observed are the same every single time - proven.
Example: Law of motions: objects in motion will stay in motion unless acted on by an outside force. 2
