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. 2. 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 1. 2. 3. 4. 5. Reviewed? Error? Accepted? Controlled? Tested? 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?
