Science is the process of learning about
the world we live in by asking questions.
Science uses observations
(what you can see, hear, touch, smell, or taste)
to investigate and answer questions about the world.

Science is the process of learning about
the world we live in by asking questions.
Science uses observations
(what you can see, hear, touch, smell, or taste)
to investigate and answer questions about the world.
All scientific investigations use similar
processes to find answers to questions.

With your nearest neighbour, create a step-by-step plan describing how you would
answer the question: “Which of three similar brands of gum is the stickiest when
chewed?”

15. Questioning
• HOW?
• WHY?
• WHAT?
• WHERE?
• WHEN?
• Have to ask the appropriate question
17. Hypothesizing
• A Hypothesis is a possible explanation that
accounts for the observations you have made.
• Must be testable
18. Hypothesizing
• A Hypothesis is a possible explanation that
accounts for the observations you have made.
• Must be testable
• Your aim is to SUPPORT or REJECT hypothesis
19. Hypothesizing
• A Hypothesis is a possible explanation that
accounts for the observations you have made.
• Must be testable
• Your aim is to SUPPORT or REJECT hypothesis
• MUST have 2 variables: independent &
dependent variable
20. Hypothesizing
• A Hypothesis is a possible explanation that
accounts for the observations you have made.
• Must be testable
• Your aim is to SUPPORT or REJECT hypothesis
• MUST have 2 variables: independent &
dependent variable
• Serves 2 jobs: suggests explanation
& guides investigation
23. Controlled Experiment
• A controlled experiment is a
test in which only one variable
is changed to observe its
effect on a second variable,
while holding all other
variables in the experiment
constant (in “constant
control”).
24. Correlational Study
• Correlational studies test how one variable
affects another variable without attempting
to control the other variables.
No correlation
25. Observational Study
• Observational studies involve observing a
subject or phenomenon in a structured
manner that does not interfere with the
nature of the subject or phenomenon.
29. Evaluating
• Judge findings
– What went well?
– What were the challenges?
– What would you do
differently next time?
• Identify errors
• Discuss results
