This document provides instruction and review of the scientific method. It begins with a warm up asking students to list what they remember about the scientific method. It then reviews the key steps of the scientific method including developing a title, problem, hypothesis, procedure, materials, performing the experiment, collecting data/results, and reaching a conclusion. The document also defines key scientific vocabulary words and has students practice applying these terms. It provides examples of experiments and homework problems for students to practice the scientific method.

1. Warm Up-
In your science notebook, list what you
remember about scientific method.

2. What is scientific method?
It is a process that is used to find answers to questions
about the world around us.

9. Homework
 Lisa Simpson Problem

10. Homeroom
 Make sure you have a SSR book
 Get yourself organized for the day
 Then, read silently

11. Warm Up-
Write in your notebook..
A scientist studies the impact of a drug on cancer.
What would be an independent variable and dependent
variable?

12. A scientist studies the impact of a
drug on cancer.
The independent variable is the
administration of the drug.
The dependent variable is the
impact the drug has on cancer.

13. Lisa Simpson Homework Problem
 Go over
 Control- one using fake hair care product
 Independent- one using the Rogooti hair care
 Dependent- amount of hair growth
 Problem (question)-Does using the Rogooti hair care
affect the amount of hair growth?
 Hypothesis (educated guess)-If the Rogooti hair care
affects the amount of hair growth then,

 Drawings for each word
 Draw a picture for each vocabulary word

15. Word
Definition
Variable
An unknown; a part
of an experiment
that changes
Independent
variable
Change that occurs
in an experiment
that is directly
caused by the
experimenter
Dependent
variable
Change that occurs
due to independent
variable
Constant
A part of an
experiment that does
not change
Control
The part of the
experiment that the
independent variable is
left out- the one thing
you are testing is not
included
Examples
Drawings

16. Scientific Method Review
 Independent- Change that
out- the one thing you are
testing is not included
occurs in an experiment that is
directly caused by the
experimenter
 Sample size- number of
individuals being tested
 Variable-An unknown; a part of
an experiment that changes
 Population- amount of a species
in an area
 Dependent-Change that occurs
due to independent variable
 Control-The part of the
experiment that the
independent variable is left
 Constant-A part of an
experiment that does not
change

17. Controls and Variable
 Read each scenario and decide what are the controls
and the variables in the problems
 Answer each question carefully
 You may use a separate sheet of paper to answer these
questions

18. Wrap Up
 Each group will share their answers from the Identify
controls and variables sheet

19. Homework
 Patty Power Problem
 Bring in poster paper by Friday 9/13/13

20. Warm UpAnswer in your notebook..
What is the difference between an
independent variable and a dependent
variable?

21. Independent vs. Dependent Variable
 Change that occurs in
an experiment that is
directly caused by the
experimenter
 What do I change?
 May be part of the test or
research
 Change that occurs due
to independent variables
 What do I observe?

22. Scientific Method Review
 Independent- Change that
out- the one thing you are
testing is not included
occurs in an experiment that is
directly caused by the
experimenter
 Sample size- number of
individuals being tested
 Variable-An unknown; a part of
an experiment that changes
 Population- amount of a species
in an area
 Dependent-Change that occurs
due to independent variable
 Control-The part of the
experiment that the
independent variable is left
 Constant-A part of an
experiment that does not
change

23. Controls and Variable
 Read each scenario and decide what are the controls
and the variables in the problems
 Answer each question carefully
 You may use a separate sheet of paper to answer these
questions
