2.Copy and Answer the following
question on your bellwork sheet:
A teacher wants to see how the
students perform best in a cold room, a
comfortable room, or a warm room.
What are the independent and
dependent variables?
Making a Hypothsis
• A hypothesis is a possible explanation to the
question or problem.
• It must be TESTABLE, which means we need to
state it in a certain way…
If I…then…because…
• We use the “If …then…because…” format.
Example:
How does the temperature of the room affect the
students’ performance on a test?
IF different groups of students take a test in a warm
room (85⁰F), a comfortable room (74 ⁰F), and a cold
room (60 ⁰F), THEN the students who test in the
comfortable room will score higher BECAUSE they
will not be distracted by their discomfort.
Hypothesis Practice
1. Tape the hypothesis practice sheet onto the next
blank LEFT SIDE page of your INB.
2. Record your answers on the next blank RIGHT side.

Data Versus Evidence
Investigate the Difference
Sigma science 2011

• How can we use data and
evidence to develop and support
good claims?
Data
• Information observed and collected as a result
of an investigation
What do we know about evidence?
• Is organized and written in complete and
accurate sentences.
• Uses information that is related to your
drawing or model.
• Makes a direction connection between
observations made during an investigation
and current research
• Shows your thinking about how the evidence
supports the claim
Does all data = evidence?
• Does every observation or piece of information
collected become evidence for a claim?
• Why not?
• If data and evidence were the same, then
wouldn’t every observation or piece of
information be required to support a claim?
• Why not?
• Then how do you choose which data to use as
evidence?
To construct evidence from data:
•
•
•
•
•
Analyze
Interpret
Look for patterns
Reason
Think about the data with respect to the
question we are trying to answer.
All evidence requires data, but
not all data needs to be used for
evidence
• Do I need to use all the data to
support my claim?
• Do scientists only collect the
necessary data to support their
claim?
