What is Science and Life? Test Friday, October 14th Review Session Friday Morning
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
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 vsMulticellular Which Is Which? Uni = ONE Multi = MANY
AutotrophvsHeterotroph Autotroph = Has ability to make its own food Heterotroph = Does not have the ability to make its own food
Redi’s Experiment What happened?.... • Two identical jar with meat • One has a cover • One does not
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 Difference between “ology” and “ist” ending? Biology = Study of Life Cytology = Study of Cells Entomologist = Scientist who studies insects Microbiologist = Scientist who studies microscopic organisms
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?
