Scientific Method
Before it starts...
You must OBSERVE
Step 1
Step 2
Research and Collect Data
Step 3
Step 6
Communicate your Results
Observe anything in nature and figure out what you want to KNOW!
What do you want to
Find already known information to help answer your question.
An educated guess of something that could be an answer to your question.
smoke from matches is mixed with water,
an acid will form.
Step 4
Was your hypothesis
? What could have changed the outcome?
***A rejected hypothesis is NOT a failure. You can learn just as much!!
Step 5
Analyze your data and draw conclusions!
Scientists study factors called independent and dependent variables to find results.
Independent Variable- the part of the experiment that the scientist is changing
Dependent Variable- the part of the experiment that is being observed and/or measured.
Constants- Conditions that DO NOT change during an experiment.
What is science?
-observing, studying, and experimenting to find the nature of things
What is the difference between theories and laws?
All science starts with observations
There is a jar of cotton balls on the front table, what are the steps you would go through to guess how many cotton balls are in the beaker?
Law: a fact that has been proven by scientific analysis.
Theory: a widely accepted idea that is supported by a wide range of evidence but has yet to be proven.
Tables and graphs are usually used to do this!
