1. Bell Ringer
Complete Conclusion Questions from yesterday’s lab.

2. Bell Ringer
Before time is up, list all the facts that you can remember from this class from last semester. (whoever gets the most, might get a prize)
3 minutes…go!!

3. Bell Ringer 8-18-09 What are 3 ways scientists think?
What are the two types of observations?
Give an example of each type of observation. You can
write them beside #2.

4. Scientific Inquiry
Chapter 1 Section 2

5. Scientific Inquiry is the ongoing process of discovery in science.

6. Scientific Inquiry refers to the different ways scientists study the natural world.

7. The Process of Inquiry Posing questions (scientific)
Developing Hypotheses
Designing Experiments (variables)
Collecting and Interpreting Data
Drawing Conclusions
Communicating Ideas and Results

8. Scientific Method… 7 Steps
Identify the problem
What do you want to know
Research
Collect information needed for questions
Ask questions or use the internet
Form a hypothesis
This is an educated guess to your problem
Experiment
Test your hypothesis
Manipulated (Independent) vs Responding (Dependent) Variable

9. Repeat....Repeat.…Repeat…Repeat some more
5. Observe
What’s happening in the experiment
What do you see
Collect data
write down what’s happening in tables, charts, etc.
Draw a conclusion
The answer to your hypothesis
What you learned from the experiment
Repeat....Repeat.…Repeat…Repeat some more

10. After the seven steps are done you should communicate your results with other scientists.

11. Experimenting
While experimenting there are some factors that are important.
You need to examine all variables.
Variables are factors that can change in an experiment.

12. Types of Variables: Independent (manipulating) the one you change
dependent (responding)  expected to change as a result of changing the independent variable

13. How Science Develops
Scientific Models
Scientific Laws
Scientific Theories

14. 1. Scientific Model- representation of an object or event used as a tool to understand the natural world

15. 2. Scientific Law- a rule that describes a pattern in the natural world.
This is usually a statement that describes what scientists expect to happen every time under a particular set of conditions.
Ex: Sky Diver- Based on The law of gravity the sky diver will eventually land back on earth

16. 3. Scientific Theory- explanations that have been tested repeatedly and have the same results.
Future evidence may not support a theory due to the increase of technology so scientists may modify the theory or discard it.
Ex: Sun revolved around the earth  new evidence  earth revolves around sun

17. Exit Quiz 8-18-09 What unit measures length?
What do quantitative observations involve?
Give an example of a quantitative observation.
What are the two types of variables we discussed today?
Which variable is the one we change on purpose?
