Scientific Method
What is the first step of the Scientific Method?
Collecting Observations
What does it mean to make an inference?
Making an educated assumption
statements based on previous knowledge
(yawn = tired)
List the 7 properties of life:
Crazy Rabbits Make Hilarious Hats Really Great
1. Cellular Organization
2. Reproduction
3. Metabolism
4. Homeostasis
5. Heredity
6. Responsiveness
7. Growth and development
What is Heredity?
THE PASSING OF CHARACTERISTICS FROM PARENTS TO OFFSPRING in DNA
Name 4 safety tips
1. Lab coat and goggles in lab
2. Electric hot plates are safer than a Bunsen burner
3. Close toed shoes
4. No hairspray- flammable
What is the second step of the Scientific Method?
Asking Questions- this helps to identify the problem
What is a hypothesis?
possible explanation made from direct observations
-How cells are organized
-All living things are made of cells
What is Responsiveness?
To React-
ALL LIVING THINGS RESPOND TO A STIMULUS (something that causes a response)
Name the lab equipment for letters A-G
A. Hand Lens
B. Dissecting Tray
C. Dissecting Pins
D. Forceps
E. Dissecting Scissors
F. Probe
G. Scalpel
What is the third step of the Scientific Method?
Form a hypothesis
What is a theory?
Explanation based on many observations and experimentation
What is Reproduction?
Members of the same species must reproduce to create fertile (able to make babies) offspring.
What is Growth and Development
ALL LIVING THINGS HAVE A LIFE SPAN
-BORN
-GROW
-REPRODUCE
-DIE
Name the lab equipment for letters H. to O.
H. Safety Goggles
I. Triple Beam Balance
J. Graduated Cylinder
K. Test Tube
L. Beaker
M. Test Tube Rack
N. Bunsen Burner
O. Dropper
What is the fourth step of the Scientific Method?
Experimentation
Which needs to be tested - hypothesis or theory?
A hypothesis needs to be tested.
A theory is based on a great deal of testing that has already been done.
What is Metabolism?
The chemical processes occurring within a
living cell or organism that are necessary for
the maintenance of life.
What is an indirect observation?
Using tools to aid the five senses
Explain the difference between a dependent and independent variable.
Independent variable- thing that you change
Dependent variable - thing that you measure because of the change
What is the fifth step of the Scientific Method?
Draw conclusions
What is a direct observation?
Observation made by using the 5 sense
What is Homeostasis?
Balance-
The ability or tendency of an organism or cell
to maintain internal equilibrium by adjusting
its physiological processes.
What is a variable?
Anything that can change or be different in an experiment
