1. SQUADS #4 Learning Intentions - Today, I am going to address these College Readiness Standards in Science: 1.Scientific Investigation – 20-23 2.Scientific Investigation – 20-23 3.Evaluation of Models, Inferences, and Experimental Results – 20-23 4.Evaluation of Models, Inferences, and Experimental Results – 28-32 5.Interpretation of Data – 24-27 6.Scientific Investigation – 24-27 Success Criteria - I will know I am successful when I can understand a simple experimental design, identify a control in an experiment, select a prediction that is supported by a data presentation or model, use new information to make a prediction based on a model, determine how the value of one variable changes as the value of another variable changes in a complex data presentation, and predict the results of an additional trial in an experiment. “10 th Grade Science” CPW 16

2. Quick Note! Today’s question are based on the printed passage you will receive shortly. After reading your passage individually or as a group, choose the best answer to each question. You may refer to the passages as often as necessary. You have 3 Minutes to read your passage! ACT Tip - The most important thing you should know about the ACT Science Test is that it is not a science test, but instead a REASONING test. It is designed to test your ability to understand and learn scientific material.

3. 10 th Grade Science #1. Which of the following statements is true of Experiment 1? F. Beetle A reproduces quicker than Beetle B. G. Caterpillars have a greater number of offspring than beetles. H. Beetle B consumed a greater amount of resources than Beetle A. J. After ten weeks, there was no difference in population size between the two species of Beetle.

4. 10 th Grade Science #2. Which of the following statements best describes why Experiment 1 is important? A.Experiment 1 demonstrates that insects can thrive under the given conditions. B.Experiment 1 establishes that both Beetle A and Beetle B eat whole-wheat flour. C.Experiment 1 establishes the non-competitive total population of each insect. D.Experiment 1 demonstrates that the caterpillar has a much slower growth rate than the beetles.

5. 10 th Grade Science #3. If Beetle A in Experiment 1 was left to grow indefinitely, one would initially observe an increase, followed by a brief plateau, and then a rapid decline in the population size. What would be the most likely cause of the final decline? F. other species of insects G. limited supply of food H. limited supply of minerals J. long-term effects of confinement

6. 10 th Grade Science #4. What would happen if, in Experiment 2, Beetle B and caterpillars were put in the same vial? A.The caterpillars would die by Week 10 because of overpopulation by Beetle B. B.The average population of Beetle B would reach 100 and the average population for caterpillars would reach five because of competition for food. C.The average population of caterpillars would reach 50, while Beetle B would die because caterpillars are stronger competitors for food. D.The average population of Beetle B would reach 500 while the average population of caterpillars would reach 20, as in Experiment 2.

7. 10 th Grade Science #5. Which of the following statements is true of Experiment 3? F. Beetle B is the more dominant of the two beetle species. G. Beetle A and Beetle B compete for space, food, or both. H. The population size of Beetle B is smaller than Beetle A due to migration. J. The population size of Beetle B is smaller than Beetle A due to the absence of the caterpillars.

8. #6. Suppose that, instead of starting with six of each species in Experiment 3, only three of each species were placed in the vial. After ten weeks, what percentage of the total population would the Beetle B species constitute? A.15% B.25% C.75% D.85% 10 th Grade Science
