  1. CPW • Learning Intentions - Today, we will address these College Readiness Standards in Science: • Evaluation of Models, Inferences, and Experimental Results, 20-23 • Scientific Investigation, 24-27 • Evaluation of Models, Inferences, and Experimental Results, 28-32 • Scientific Investigation, 24-27 • Scientific Investigation, 20-23 SQUADS #2 11th Grade Science Success Criteria – You know you are successful when you can compare data from a simple data presentation, interpolate between data points in a table or graph, and select a prediction that is supported by a data presentation.

  2. Please Note • You have 4 Minutes to read your passage. • You will have 1 minute and 15 seconds to work on each question individually. • You will have 1 minute and 30 seconds to work as a group and write your rationales for each answer.

  3. Grade 11th Science #1. Based on the results of Study 4, how did fragmentation most likely affect the population sizes of insectivores and hummingbirds in the fragments studied? • Fragmentation increased the population sizes of both insectivores and hummingbirds. • Fragmentation decreased the population sizes of both insectivores and hummingbirds. • Fragmentation increased the population size of insectivores and decreased the population size of hummingbirds. • Fragmentation decreased the population size of insectivores and increased the population size of hummingbirds.

  4. Grade 11th Science #2. Based on the results of Study 1, if the distance from the center of a 100 m x 100 m plot were 75 m from the nearest clearing, the expected average change in AGTB at the plot over 17 yr would be closest to which of the following values? • -1.1 t/yr • -2.6 t/yr • +1.1/yr • +2.6 t/yr

  5. Grade 11th Science #3. After examining the results of Study 2, a student concluded that the AGTB at each of the 25 plots remained constant. Which of the following alternative explanations is also consistent with the results? • The AGTB at all 25 plots increased. • The AGTB at all 25 plots decreased. • The AGTB at some of the plots increased and the AGTB at some of the plots decreased. • The AGTB at plots bounded by forest increased and the AGTB at plots bounded by clearings remained constant.

  6. Grade 11th Science #4. Which of the following sets of results from the studies is least consistent with the prediction proposed by the researchers? • The results of Study 1 for AGTB • The results of Study 3 for AGTB • The results of Study 4 for frugivores • The results of Study 4 for hummingbirds

  7. Grade 11th Science #5. In Study 4, the researchers trapped birds for 10,000 hr per year. Thus, how many insectivores were trapped in Year 2? • 80 • 100 • 800 • 1,000

  8. CPW 11th Grade Science • Repeat the questions with your squad members. Be sure to write a rationale. If you don’t write a rationale, you won’t learn as much. Your brain is like a muscle. Use it! • 1 minute and 30 seconds per question for Squad Mode. • After the rationale writing is done, launch the Answers video.
