Bellwork: 8/30 Put phone up Week 8/28-9/1 What is wrong with the graph to the right? These 2 points lie on your best fit line: (14,60) & (22,85). Write the equation of the best fit line (b=50).
Objective Learn how to write conclusion & reflection Discuss challenge project & begin design
Today: Part VI Notes Discuss Challenge Project Start project design

Unit I: Nature of Science
Part VI: Conclusion
Conclusion Conclusion: the summary and interpretation of experimental results at the end of a lab write up
Purpose Experiments are only meaningful if you can interpret data & convey its meaning to your audience in a clear and concise manner
Conclusion Conclusion should contain 4 components: State CLAIMS Use NUMERICAL EVIDENCE to justify the claims RESTATE HYPOTHESIS – reject or accept based on evidence MAKE INFERENCES using prior knowledge Tell what data means
Observation vs. Inference Observation – description of natural structures and processes Can involve 5 senses – seen, tasted, heard, touched, or smelled Measurements taken with scientific tools (pH meter, thermometer, balance, etc.) Inferences – conclusions based on observations Goes beyond what is directly sensed or measured Provides meaning to the observation based on prior knowledge
Example of Inferences Examine the picture to the right Write: Observations – what you detected with your 5 senses Inferences – your interpretation of that observation
Reflection After you write your conclusion…write a reflection Reflection includes… Identification of possible errors committed during the lab How errors affect results How the lab is related to biological concepts taught in class Should be a minimum of 4-5 sentences

Choose your group Choose your topic If you choose something that is NOT listed, I need to approve it Every group needs to do research about their scientific question to determine variables…write down websites used Phones are allowed today…for research only… Start filling out design paper…#1, 2, & variables for 3 (do NOT write procedures) & then get initialed by me!!!
