Scientific MethodSlide2
Observations
Very important
Things that make you go “Hmmm?”
Survival techniqueSlide3
Questions
An art form
Differing perspectives
Good questions make good discoveries (I wonder what will happen if I…?)Slide4
Hypothesis
It’s what you
think
will happen, based on what you know
Needs to be answerable
Needs to be testableSlide5
Experimental Design
The “test”, crucial
Variables- change
Independent vs. Dependent
Groups
Control vs. Experimental
ControlsSlide6
Report
Discuss your findings
Was your hypothesis correct? Why or why not?
What went wrong? (errors)
What would you do differently?Slide7
Caveman Dave
Observation:
A lot of deer drink water at Lake
Hoochimuma
during the nightSlide8
Caveman Dave
Questions:
Could I drink that water? (same)
Is that a good spot to catch deer? (similar)
Will there be a saber-toothed tiger around? (extended)Slide9
Caveman Dave
Hypothesis:
I think it’s water and water is safe to drink
I think if I hunt there at night I will capture more deer
I think if I go near the lake I will be attacked by a saber-toothed tigerSlide10
Caveman Dave
Experiment #1
For the next week, 10 people drink from the river and 10 people drink from the lakeSlide11
Caveman Dave
Variables:
Independent- what are we changing/adjusting?
Dependent- what is our expected goal/result. Can we measure it?Slide12
Caveman Dave
Groups:
Control- old or normal conditions
Experimental- new conditions or changesSlide13
Caveman Dave
Controls- what should we keep the same?Slide14
Caveman Dave
Experiment #2
For the next month, 10 people from the Cave hunt for deer at night and 10 people from Caveman James’ Cave will hunt during the daySlide15

Variables:
