1. G.O.T. = Get On Task Begin Packet on Scientific Process
Measurement TOPIC 1,2,3
MY GOAL
G.O.T. = Get On Task
Wed
Begin Packet on Scientific Process
I will learn more about designing an experiment
Copy these on ISN page 7
QuaNtitative vs. Qualitative
25%, minutes, 10 miles
The bear moved slowly through the woods

2. Procedure …. AKA “What are we doin’ today?”
Get on Task: Control Group vs Constants
Review Bias & Ethics & Graphing
Review how to write a hypothesis
Complete ISN page 13, Identifying Parts of Exp.
End of Class Assignment

3. ISN page 9 2 questions… Obs./Ques. Back. Info. Hypoth. Exp.IV DV
Results – graph, chart
Concl. – narrative
Applic.
What part of the Scientific Process would contain QUANTitative Info?
What part would contain QUALItative info?

4. Comparing Hypothesis, Theory, Law
ISN page 7
Comparing Hypothesis, Theory, Law
#2 HYPOTHESIS
#7 THEORY
#8 LAW
Testable statement (NOT opinion)
Supported thru experimentation
Summarizes a hypothesis or a group of hypotheses
Valid as long as there is no evidence to refute it, so it CAN change
Generalizes a body of observations
At the time it is made, NO EXCEPTIONShave been found

5. ISN page 13, Scenario #1 IV = Test DV = Outcome Constants = Control =
Hypothesis =
Improvement =
Type of pellet (CAUSE)
Accuracy of pellet (EFFECT)
same type of rifle, shot same # of times, target same distance away
Standard Brand X Pellets
IF I use a ‘specific type’ of pellets (CAUSE)
THEN I will hit the target 9 times out of 10 (EFFECT)
Be aware of wind!

6. ISN Page 13, Scenario #2 IV =Test Var. DV = Outcome Var. Constants =
Control =
Hypothesis =
Improvement =
Fertilizer (CAUSE)
Height of tomato plant (EFFECT)
Same soil, equal amts. of fert., same location, same amt. of water
4th pot with no fertilizer – she cont. growing it like she NORMALLY does
IF I use 1ounce of ‘Fert X.’ for 6 months,
THEN my tomato plants will grow
5 inches
None… BUT all exp. should be REPEATED for validity!

7. ISN page 13, Scenario #3 IV = Test DV = Outcome Constants = Control =
Hypothesis =
Improvement =
Color of rice (CAUSE)
People choosing certain color rice (EFFECT)
same amt. rice, identical bowls
None
IF I use a ‘specific color’ of rice (CAUSE) for 1 week
THEN 85% people will choose the ‘normal color rice’ (EFFECT)
Needs control group  white rice for comparison

8. ISN page 13, Scenario #4 IV = Test DV = Outcome Constants = Control =
Hypothesis =
Improvement =
Studying more
10% increase in grade
None….
Previous grade
IF I study for 42 minutes/night (CAUSE)
THEN my biology grade will
increase by 10% (EFFECT)
Do not study sporadically, don’t use different study methods

9. ISN page 13, Scenario #5 IV = Test DV = Outcome Constants = Control =
Hypothesis =
Improvement =
Certain drug
Memory
Equal amounts of drug, Same # in group size same length of time, same test
Previous grade
IF given 5mL of Drug A (CAUSE)
THEN memory will increase (EFFECT)
More trials; results inconclusive  test result same

10. Stop Think And Review Questions before we move on? Hypothesis
Independent Variable
Dependent Variable
Control Group
Experimental Group
Constants

11. Last JOB TODAY
Complete More Practice, Identifying Parts of Exp. on p of NB
BTW…You MUST be able to do this ON YOUR OWN!

12. Stop Think And Reflect Did we reach our goal?
Identifying Parts of an Experiment
Did you reach that goal?
How do you know you reached the goal?
What are YOU going to do if you did not reach that goal?? 12

13. Study for MiniSummative #1 tomorrow!
EOCA = End of Class Assignment
