3. Investigating Patterns Instructions What question is on the table? The full sheet of paper represents the environment & each hole punch represents an animal of the same species with different coloring Roles: –Populator: Prepares the environment –Predator: Attacks organisms in the environment –Timer/Counter: Times attack window & organizes counting Once you are finished organizing and representing your data, come see Jess or Matt for the final task card.

8. NGSS Expectations for MS In MS, students should have opportunities to learn techniques for displaying, analyzing, and interpreting data: –Develop different kinds of graphs –Identify outliers in a data set –Average values to reduce the effects of measurement error –Explain why these techniques are needed

9. A Structure for Interpreting Bar Graphs/Histograms & Scatter Plots 1. What does the title mean? (What can we expect to learn from the graph?) - Ex. How changes in shoe size are related to changes in height 2. What does the x-axis represent? 3. What does the y-axis represent? 4. What does a point represent? 5. What are the patterns in the graph and what do they tell us? (6. What is the meaning of the slope?)

10. Does this structure work?
