Transcript introduction to variable labs

New in Notebook:
Experiment Odds and Ends
Write
down in step by step
format how you would test who
is better in basketball (using a
paper basketball and trash
can) – boys or girls in this class.
Do it in LIST or NUMBERED
format.
The Step by Step includes:
 Who?
(did the experiment)
 What? (what did they DO?)
 Where? (location matters)
 When? (often the time of day matters as
well)
 Details – someone across the country
should be able to REPLICATE your study
from your instructions.
Learning Target:
I
will compare and
contrast
engineering and
variable
experiments with a
Venn Diagram and
in the study guide.
Science Fair Notes:

are all not
monkeys
New For Your Dictionary:
 Control:
The “normal” state of your
experiment. What is normal BEFORE
