After time we will go over them.
When finished, put the papers in the CORRECT order.

Unit 6:
Solutions!
Test this Friday
What happens if you have a good
recipe but use rotten ingredients?
We practiced making conclusions
based on graphs and data tables
• The data in those graphs and tables is our
evidence, our experimental results
• We base conclusions on that evidence…
…but what if we have bad
evidence?
• Evidence is VERY important
• BUT evidence must be good to be useful
• What do we mean by good?
5 Rules of evidence
1.

3.
4.
5.
Reviewed?
Error?
Accepted?
Controlled?
Tested?
Do NOT just accept evidence,
instead REACT
Reviewed?
• Should be peer reviewed or published
• Peer reviewed- read and critiqued by other
scientists
• Published- in a scientific journal
Error?
• Should have a small known or small
potential rate of error
Accepted?
• Should be generally accepted by the
scientific community
Controlled?
• Should change only one independent
variable at a time
• Experiment includes:
– Independent variable
– Dependent variable
– Constant
– Control group
– Multiple trials
Tested?
• Should have been tested or be testable
– Specific and concrete
Example: Millikan’s oil drop
experiment

On your own…
• Review Redi’s experiment with flies
• On a separate sheet of paper apply the 5
rules of evidence
• Given your evaluation using the five rules,
is this good evidence?
• Challenge: how could this evidence be
improved?
Done Early?
• Start on homework
• Conferences
• Make up work
– intermolecular forces worksheet and foldable
• Work quietly, be respectful
Sum up
• What did we learn today?
• HW:
– Come up with your own creative way to
remember the 5 Rules of Evidence
• Top Ten:
– How’d we do?
