The first step of the Scientific Method Define or Identify the purpose/problem
What are you trying to find out?
Educated guess of what you predict is going to happen
If….Then….Because Need Variables to form hypothesis!
All the essential materials used in the lab
Should be bulleted One material listed per line Amounts should be included
Describes the steps you use during an experiment
Step-by-step format Should be numbered One procedure per
line Need diagrams to go
with procedures!
Each time you test the dependent variable, what is being changed or manipulated from the last time you tested the dependent variable?
What am I changing? What am I doing? What part am I doing differently?
Part of an experiment that is not being tested and is used for comparison
Variables that do not change are the constant variables
Makes sure the experiment is “fair”
The information collected during an experiment
Can be qualitative (observations)What do you see or observe? (anything with
the senses)Write and draw!
Can be quantitativeNumbersData Tables
Scientists make observations to help them make a hypothesis or collect data during an experiment
What did you see during the lab?
Should have a title Independent Variable in the left column Dependent Variable in the right column Amounts and Units should be included
After the experiment, scientists organize and analyze the data
How did your variables relate to one another?
What does your graph say to you??
