WHAT IS THE DIFFERENCE BETWEEN AN
OBSERVATION
& AN
INFERENCE
?
observation-judge what you see, hear, & smell, etc.
Inference-judge what you notice with your senses (observe)
Inference-notice things with your senses.

constants
when comparing 3 types of balls to see which bounces highest?
Same drop-point of ball, measuring method, height, floor.
The ball that is a "Normal" bouncing ball.
Same balls, stop the balls at same height, same floor.
Same type of balls, same bouncing, same person.
9
ONCE A SCIENTIST HAS EVALUATED THEIR DATA, & REPORTED THEIR RESULTS, THEY WRITE THIS...
The Problem.
The Results.
The Conclusion.
The Hypothesis.
10
CHOOSE EXAMPLES OF
QUALITATIVE
DATA...
There were 15 bubbles at the top of the beaker.
When Hydrogen Peroxide & water mixed, bubbles appeared.
The tomato plant was 32 cm. tall, after 20 days.
The white substance was powdery
11
THE
DEPENDENT
VARIABLE IS...
The variables you kept the same while test-ing 1 variable.
The resulting action due to testing one variable.
The response to the test done on the Independent Variable.
The variable you changed to test it.
12
A BEAN GREW: 3"-WEEK 1, 6" -WEEK 2, 9"-WEEK 3, & 12" -WEEK 4, WHAT MIGHT WEEK
5
BE?
16" TALL WEEK 5.
15" TALL WEEK 5.
18" TALL WEEK 5.

13
THE
INDEPENDENT
VARIABLE DOES THIS IN AN EXPERIMENT...
It is what "I" changed purposely to test a question.
It indicates the measurement of what is being tested.
It will answer your question when tested.
It is the response of the tested variable.
14
DON TESTS 3 WHEEL SIZES, TO SEE WHICH MAKES HIS SCOOTER ROLL FASTER.
IDENTIFY I.V. & D.V?
His I.V. is the 3 wheel sizes.
His D.V. is how fast the scooter rolls. (speed).
His I.V. is the speed that the scooter rolls.
His D.V. is the 3 wheel sizes.
15
YOU MAKE A HYPOTHESIS...
After you write the procedures of your experiment.
After you know the results, so you can be right!
After you perform the experiment.
Before you perform the experiment.
16
CONSTANTS
IN AN EXPERIMENT ARE...

The variable that shows the response to the I.V.
The variables you are testing.
All the variables you keep the same, when testing the I.V.
17
THE
1st
STEP OF THE SCIENTIFIC METHOD IS TO....
Draw a Conclusion.
Report Data.
Make a Hypothesis.
State the Problem.
