Six Steps of Scientific Method
A. Question B. Hypothesis C. Experiment D. Data Collection E. Analyze Information F. Report Results – Communication
Steps or Procedure used to test a question
Quantitative vs Qualitative Quantitative = Observation that deal
with NUMBERS• There are 15 desks in the room• There are three windows
Qualitative = Observation that cannot be expressed in numbers (LETTERS)• Bernie is green
Prediction vs Inference Prediction is a guess about what is
going to happen in the future!
Inference is a guess about what has happened or is happening right now and you cannot see
I think it’s going to rain tomorrow
Models Take something complex and make
simpler or easier to understand from a new perspective
Control and Variable Control: Group that nothing new is
being tested on
Variable: A factor in an experiment that can change
*You can only test one thing at a time!!!*
Example Mrs. Carey heard that there is a new
brand of gum called Dominator that is supposed to make you smarter. She decides to try it on her students to see if it actually works. The day of the test she gave half of her students, group A, plain gum and half the students, group B, the new Dominator gum. After grading the test she finds that group A averages a 93% and group B averages an 80%.
Needs vs Characteristics of Living Things
Needs:• Water• Food• Shelter• Homeostasis
Characteristics:• Growth• Reproduction• Metabolism• Response to Stimuli
Unicellular vs Multicellular Uni = ONE
Multi = MANY
WhichIs
Which?
Autotroph vs Heterotroph Autotroph = Has ability to make its
own food
Heterotroph = Does not have the ability to make its own food
Redi’s Experiment Two identical jar with meat
•One has a cover•One does not
What happened?....
Stimulus and Response 1. One of Mrs. Carey’s students tells
a funny joke
2. A bear smelling food
3. Insect landing in a spider web
4. Pulling your hand away from fire
Lab Safety COMMON SENSE!
•What if something breaks?
•What if you hurt yourself?•Things not to do?....
Branches of Science Biology = Study of Life
Cytology = Study of Cells Entomologist = Scientist who
studies insects Microbiologist = Scientist who studies microscopic organisms
Difference between “ology” and “ist” ending?
Graphing What do they ALL
need? Can you read and
interpret the information?
Why would the graph you created be useful?
What must all the parts of a circle graph add up to?
