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.
Quick Note!
• Today’s questions are based on the printed
your passage individually or as a group,
choose the best answer to each question. You
may refer to the passages as often as
necessary.
