#4 Learning Intentions - Today, I am going to address these College Readiness Standards in Science:

1. Interpretation of Data 13-152. Interpretation of Data 24-273. Scientific Investigation 24-274. Scientific Investigation 20-235. Scientific Investigation 24-276. Interpretation of Data 16-197. Evaluation of Models, Inferences, and Experimental Results 20-23

Success Criteria – I know I am successful when I can select data from a simple graph, understand the methods used in a simple experiment, determine the experimental conditions that would produce specified results, and find basic information in a brief body of text.
