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

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?
