2. Concepts are taught…vocabulary must be understood!
THIS IS NOT SCIENCE 7…EXPECTATIONS ARE GREATER!
Concepts are taught…vocabulary must be understood!
MATURITY IS NOT THE GAINING OF KNOWLEDGE, BUT THE ABILITY TO APPLY ONESELF WITH PURPOSE IN A MEANINGFUL COMMUNITY

4. 8 Simple Rules for Classroom Behaviour
‘Follow these, and we will have a great year’
Respect one another & property at all times
Use good manners
Do your own work
Follow directions
Keep hands, feet, objects, and unkind remarks to yourself
Bring required materials to class
Raise your hand
Do not bring unnecessary/distracting materials

5. Mr. Tadic’s Class Binder Checks may be given periodically!!
How you should set up your science binder:
1. Notes
2. Homework
3. Labs/Activities
4. Quizzes/ Tests
5. Extra paper (lined, white & grid)
Binder Checks may be given periodically!!

6. Mr. Tadic’s Class Come prepared with all required materials!
You need your binder and textbook everyday, but may need other materials time to time.
Not coming prepared with the proper equipment is not an excuse to not do your work! (nor leave class to get it)
Be prepared to clean out your locker!
Entering & leaving class
Cellphones- Will Be Confiscated!!
Plagerism…(sigh)
You should know what a vacuole, not endoplasmic reticulum!
Difference between group work and your work

8. The Scientific Method- How does science work?
Scientific method is not a recipe: it requires intelligence, imagination, and creativity.
It is also an ongoing cycle, constantly developing more useful, accurate and comprehensive models and methods.

9. Outline of the Scientific Method
1) Question (ie. What is the Problem?)
2) Hypothesis
3) Create Operational Definitions
Materials
Procedure
Variables
Controlled
Manipulated
Responding
4) Observations (in chart or graph)
5) Analyze data
6) Reliability/Validity
7) Conclusion
8) References

10. 7 Points When Talking Science…
Observations
Types of Observations
Accurate – exact report of what your senses tell you.
Objective – avoids opinion or bias on a specific point of view. (opposite = subjective)
Quantitative – have numbers, but also can include descriptions.
Qualitative – do NOT have numbers, only descriptions.
Hint: describe one of these observations in your lab reports!

11. Observations Examples

12. B) Measuring
provides specific information and help observers avoid bias.
Needs to be accurate!

13. C) Classifying
organizing ideas, objects and events into groups according to a system.
good classification systems make finding information easier and clarifies relationships.

14. D) Hypotheses
a prediction about the outcome of a scientific investigation.
must be testable by observations.
For our purposes, it is a cause and effect, or ‘if-then’ statement. Explain why after.
‘if the temperature is decreased, then the seedlings will not grow as well’. Why…
‘ if the amount of moisture is increased, then the bread will get moldier’. Why….

15. E) Variables Variable -> factors that can change. 3 types
1) Manipulated Variable (independent variable)
1 variable that is purposely changed and tested
2) Responding Variable (dependent variable)
the 1 factor that may change as a result of the manipulated variable
- this is what you are trying to find out
3) Controlled Variables
all the other factors (3-4 different factors)
must keep ALL conditions the same.

16. Examples
How does the amount of fluoride affect the number of cavities?
Manipulated variable =
Responding variable =
Controlled variables =
Is the number of tomatoes on a tomato plant affected by the amount of fertilizer used?

17. F) Graphing Data
Allows one to see patterns and trends that are very difficult to spot from a table of numbers.
(don’t copy) BE SURE YOU KNOW HOW TO PROPERLY DRAW A GRAPH (website referral)

18. Graphing the Variables
the manipulated (math terms: independent) variable is always plotted against the responding variable (math terms: dependent)
Y Axis
(responding
variable)
Units
X Axis (manipulated variable) Units

19. G) Interpreting Data (Analysis)
means looking for a pattern or trend.
Ie. What happened? Detailed explanations!
Hint: pretend the teacher knows nothing about science. You need to explain every little detail.

20. The metric system To Summarize:
Kilo Hecto Deca (Meter) Deci Centi Milli Micro Nano
K h da (m) d c m u n
X by ______ (or keep adding zeros to the end)
÷ by ______ (or keep taking zeros at the end)

21. Safety in the Science Classroom
Safety test to follow!!!
Know the WHMIS symbols!
Always wear SAFETY GOGGLES!
Always put lids back on containers!
Safety Review
