Calorie Lab rewrites

Photosynthesis Lab What reaction were we using to determine photosynthesis was happening? How do your results show THAT?

Hypothesis Testing Hypothesis and Null Hypothesis You really test your null If you can REJECT your null hypothesis… If you CAN’T reject your null hypothesis…

A note on Means (averages) What is the mean for each group? Which group is BEST represented by that mean? Why? Is there a way to convey that to the reader? Group 1Group

Written summary of results Graph (and table), include your explanatory and response variables Can you reject your null hypothesis? EXPLAIN! What reaction and how/why? Everything should be framed within what we were trying to do Turn in your results and discussion Results Discussion

Category Criteria Results Written summary of results. Explanatory and response variables were included pts Graph/table Appropriately labeled graph and table; graph correctly depicted appropriate data/results. Calculations pts Discussion Reject/fail to reject null? Accurate summary and answer to question pts Description of reaction used. This should be complete enough to allow reasoned argument and include how you know it was that reaction pts Plausible explanation for your results (or failing to reject null hypothesis). Explanation/argument should include photosynthesis pts Experiment Propose a new experiment to test/retest a hypothesis 0-10 pts

Homework Photosynthesis Report due Monday NO chance for re-writing it, so follow the rubric!!!
