Good morning!Warm-up 8/18/16

• This is your first warm-up. Warm-up reqs
• Write the date on the left side, title it
  warm-up and the number of the warm-up, and answer
  in complete sentences. You do not need to write
  the question.
• What is science?
• How do we study science?
• What is the purpose to studying Biology?

2
Warm-up 2

• 1. Which is used for handling hot glassware
• A. tongs. C. rag or paper towels.
• B. Your bare hands D. forceps
• 2. Can personal eyeglasses be used in place of
  goggles?
• 3. What is the correct heading for any assignment
  you pass in? (hint on the upper left side of the
  page)

Warm-up 3 8/25/16

• A student wondered why perishable food (like
  meat) is supposed to be placed in a refrigerator.
  Thinking about it, she remembered that she had
  left some meat on the counter once, and it had
  started to rot. She also knew from her BIOLOGY
  class that rotting is caused by bacteria. The
  student decided that bacteria probably grew less
  quickly in a cold environment.
•  1. Identify the following parts of the
  students
• investigation 
• A. Question
• B. Observations
• C. Hypothesis

Warm-up 4 8/29/16

• Write the definition of the word Bias
• A tendency to believe that some people, ideas, or
  thoughts are better than others based on an
  individuals experience.
• 2. Do you think biases effect science? Why or why
  not.

5

• To see if she was right, the student took three
  identical containers of chicken soup and added a
  small amount of bacteria to each one. She placed
  one container in the refrigerator, one on the
  counter, and one on top of a warm radiator. After
  five days, the student used a microscope to look
  for bacteria in each sample of soup. She found
  that the soup in the refrigerator had very few
  bacteria, while the soup on the counter had more.
  The soup on top of the radiator was the worst
  it was absolutely teeming with bacteria.
• Identify the following parts of the
  students experiment
• 2. Independent (manipulated) variable
• 3. Dependent (responding) variable
• 4. Controlled variables (those that never change)

6

• Science is an organized way of using evidence to
  learn about the natural world.
• We study science by observing, asking questions,
  and designing experiments to tests hypotheses.
• Biology is the study of life, and seeks to
  understand the living world

7

• With your partner, answering the following below
  your warm-up.
• Define observation
• Define hypothesis
• What is a bias?

8

• Observation- information gathering in a careful,
  orderly way. Usually involves the senses
• Hypothesis- proposed explanation for a set of
  observations
• Bias- to have an inclination or tendency to think
  a certain way based on your life experiences to
  have a prejudice or a favored opinion

9
Warm-up 5 8/31/16

• Match the words w/ their appropriate meaning
• Manipulated variable responding
  variable
• Theory data hypothesis
  controlled experiment
• The variable that the researcher deliberately
  changes
• The variable that changes in response to the
  variable that is changed
• A proposed explanation for a phenomena
• Information gathered from observation
• Testing the effect of a single variable by
  changing it and keeping all other variables the
  same

10
8/25/15 Warm-up 4

• Match the following vocab with their meanings
• Spontaneous generation theory cell
• Homeostasis metabolism stimulus
• The smallest unit of life
• Keeping conditions in a living organism constant
• A signal to which an organism responds
• Well-established explanation that unifies a broad
  range of observations
• Idea that life can arise from nonliving matter

11

• Biology is the study of life, and seeks to
  understand the living world
• We study science by observing, asking questions,
  and designing experiments to test hypotheses
• Data-information gathered from observations
• Qualitative-descriptions and appearances
• Quantitative-what can be measured

12
Warm-up 8/21/14

• Theory-a well supported hypothesis accepted by
  the scientific community.

13

• SCIENCE IS AN ONGOING PROCESSSCIENTIFIC
  UNDERSTANDING IS ALWAYS CHANGING

14
Thinking like a Scientist

• Inference- a logical interpretation based on
  prior knowledge or experience
• -Uses data
• Hypothesis- proposed explanation for a set of
  observations
• -Must be able to test the hypothesis

15
Thinking like Scientists Puzzle

• Each group will have an envelope with puzzle
  pieces. Every student must draw the table below
  in their notebooks
• Observation Hypothesi
  s
• 1 puzzle piece
• 5 puzzle pieces
• 10 puzzle pieces
• 20 puzzle pieces
• Final Group
• Hypothesis

16
Opening Thought

• Scientific investigation often begins with an
  observation that leads to a question. Careful
  observations are the foundation of scientific
  investigation.
• What are some questions you have about natural
  phenomena of life that can be tested?

• For centuries, people believed in spontaneous
  generation-a theory that life could arise from
  nonliving matter
• Until 1668, a physician named Redi proposed a new
  hypothesisFlies produced maggots.
• Next step test his hypothesis

21
Designing an Experiment

• Asking a Question/Identifying the problem- Do
  flies produce the maggots?
• 2. Forming a Hypothesis- Redi analyzed the
  maggots appeared a few days after flies were
  present. He thought maybe flies were laying eggs
  too small for humans to see.
• 3. Set Up a Controlled Experiment- Whenever
  possible, a hypothesis should be tested by an
  experiment in which only one variable is changed
  at a time. All other variables should be kept
  unchanged or controlled.

22
Designing an Experiment

• Record and Analyze Results- record all
  observations and data. This can include pictures,
  graphs, tables, etc.
• 5. Draw a conclusion communicate the results-
  use the data from the experiment to evaluate the
  hypothesis.
• Is this data allowing the scientist to come to a
  valid conclusion? Is the hypothesis supported or
  refuted?

23

• Variables-factors in an experiment that can
  change.
• Ex. time, type of equipment, temperature,
  place, light, etc.
• You should only change ONE variable, the rest are
  kept unchangedcontrol group (what is kept
  constant)
• Manipulated (independent)- this you can change!
• Responding (dependent)- acting in response to
  the manipulated variable

24
Warm-up 5 8/27/15

• Metric system Microscope Sexual reproduction
• Asexual reproduction Metabolism
• Produces magnified images of structures too small
  to see with the unaided eye.
• Decimal system of measurement using multiples of
  10
• Chemical reactions through which an organism
  builds or breaks down materials
• Cells from two different parents unite to form
  offspring
• Single parent produces offspring
