1. If you did not pick up homework yesterday do so today!! Due FRIDAY
Get out ISN we are taking notes over Scientific Method/Lab Write up
Tutorials tomorrow morning for lab make-up and homework help 8am

2. Scientific Method/Lab Write up
An orderly and systematic way of solving a problem

3. QUESTION YOU ARE SEEKING AN ANSWER FOR
1. PROBLEM
QUESTION YOU ARE SEEKING AN ANSWER FOR

4. ALWAYS IN THE FORM OF A QUESTION.
Does the amount of liquid affect the growth of plants?
Does the type of liquid affect the growth of plants?
Does the amount of light affect the growth of plants?
Does the type of soil affect the growth of plants?
MUST BE ABLE TO ANSWER THROUGH EXPERIMENTATION

5. -RESEARCH
COLLECT KNOWN INFORMATION
EXAMPLE: RESEARCH
READ
OBSERVE

6. -PREDICTION
A LOGICAL GUESS OF AN OUTCOME BASED ON DATA AND PRIOR KNOWLEDGE. IF YOU HEAR THUNDER, YOU COULD PREDICT THAT IT WILL RAIN.

7. EDUCATED GUESS TO ANSWER THE QUESTION
2. HYPOTHESIS
EDUCATED GUESS TO ANSWER THE QUESTION
The more research, the better our hypothesis

8. Should be written in an “if- then” statement
I think if the amount of light is changed, then the plant growth will be affected.
I think if the type of liquid is varied, then the plant growth will change.
I think the type of fertilizer affects plant growth.

9. Face Book Activity # Post Try to organize hypothesis 3 --------- 5 710

10. 3. EXPERIMENT PLANNED WAY OF SOLVING A PROBLEM WRITTEN AS STEPS
KNOWN AS PROCEDURE.

11. GIVING INSTRUCTIONS LAB
Tell me how to make Peanut butter and Jelly Sandwich

12. GIVING INSTRUCTIONS
Quick Write- Using 5 complete sentences, describe what happened and write what you learned

13. FACTORS IN AN EXPERIMENT THAT CHANGE
VARIABLE
FACTORS IN AN EXPERIMENT THAT CHANGE

14. 1. Independent Variable M- Manipulated I- Independent X- X axis
This is the variable that you are purposefully changing.
YOU MAY ONLY HAVE 1 INDEPENDENT VARIABLE

15. 2. Dependent Variable D- Dependent R- Responding Y- Y axis
This is the variable you are measuring it will be recorded in your data!

16. CONSTANT
FACTORS IN AN EXPERIMENT THAT A SCIENTIST PURPOSELY KEEPS THE SAME.

17. group that serves as the standard of comparison.
CONTROL
group that serves as the standard of comparison.
Treated as the same as the samples, but not exposed to the independent variable

18. Peanut Butter Jelly Time!
Write the procedure to make a peanut butter jelly sandwich. Be sure to write them in steps and be specific!

19. 4. DATA/ OBSERVATIONS
COMPILE DATA
INFORMATION COLLECTED FROM EXPERIMENTS

20. -OBSERVATION
DATA THAT YOU COLLECT THAT YOU CAN PHYSICALLY OBTAIN USING YOUR 5 SENSES.

21. -INFERENCE
LOGICAL INTERPRETATION BASED ON PRIOR KNOWLEDGE AND EXPERIENCE. IF SOMEONE IS WET, YOU COULD INFER IT IS RAINING OUTSIDE.

22. Observations vs. Inferences
The plant has roots.
The plant uses water.
The plant has leaves.
The plant has flowers.
The plant grew from a seed.
The plant is growing in soil.
The plant is green and yellow.
The plant is growing in a pot.

23. Young people are playing basketball.
The players are in high school.
People are watching the game.
The score is tied.
The game is almost over.
The people are indoors.
There are 6 players

24. MYSTERY Diapers List 5 observations List 5 inferences
(I see, I feel, I smell, etc)
List 5 inferences

25. PRECISION
MEASURING WITH ACCURACY AND EXACTNESS. A MEASUREMENT OF 5.5CM IS MORE PRECISE THAN 5CM.

26. AVERAGING NUMBERS
MANY TIMES SCIENTISTS WILL HAVE SEVERAL ANSWERS FOR A PART OF AN EXPERIMENT. The best method of dealing with this situation, is to average.

27. EXAMPLE OF AVERAGING
ADD THE DIFFERENT ANSWERS TO REACH A TOTAL. THEN DIVIDE THE TOTAL BY THE NUMBER OF DIFFERENT ANSWERS.

28. GRAPH
A PICTURE OF DATA- NUMERICAL DATA

29. KINDS OF GRAPHS 1. CIRCLE GRAPH A. DIVIDED CIRCLE
B. SHOWS HOW A PART OF SOMETHING RELATES TO THE WHOLE VALUE.

30. BAR GRAPH
HELPS YOU COMPARE THINGS SUCH AS –
AMOUNTS or QUANTITIES

31. LINE GRAPH A. LETS YOU PLOT SEVERAL DIFFERENT FORMS OF DATA.
B. HELPS YOU SEE PATTERNS OR TRENDS.

32. TAILS Title: Includes both variables
Axis: IV on X-axis and DV on Y-axis
Interval: The interval (4) is appropriate for this scale.
Label: Both axes are labeled.
Scale: Min and max values are appropriate.

33. Plant Growth
time (days)
height (cm) 1 15 7 26 14 33 21 47 24 54 30 60

35. GRAPHING DEDUCTIONS Title (5) X & Y title (5) X label/ scale (5)
Y Label/ scale (5)
Start at zero (5)
Straight lines (5)
# increments (5)
IV/ DV (20)
Plot (20)

36. 5. CONCLUSION
ANSWER TO THE PROBLEM

37. MOST LOGICAL EXPLANATION FOR EVENTS THAT HAPPENED
THEORY
MOST LOGICAL EXPLANATION FOR EVENTS THAT HAPPENED

38. LAW
A THEORY THAT HAS BEEN TESTED MANY TIMES AND IS GENERALLY ACCEPTED AS TRUE.

39. REPLAY Conclusions R – restate the problem question
E – explain what you did to test
P – pull in the data
L – look for patterns
A – answer the problem question
Y – yes or no to hypothesis (hypothesis correct? Why or why not?)
