  1. Bell ringer At the wavelengths used in Study 1, as the wavelength of the light increases, the reflectances of the S allotropes and of SO2 do which of the following? S allotropesSO2 1. Increase only Increases only 2. Increase only Increase, then decrease 3. Increase only Decrease only 4. Decrease only Increase, then decrease

  2. SWBAT explain types of science passages on ACT

  3. ACT Science

  4. 3 types of passages • Data interpretation – 38% of questions 3 out of 7 passages • Research summaries—45% of questions 3 out of 7 passages • Conflicting viewpoints—17% of questions 1 out of 7 passages

  5. No specific facts required! Test is on your ability to: • read graphs and tables • Identify IV, DV, CV • Read and make conclusions about hypotheses and models

  6. Data interpretation Reading graphs and tables --bar graphs, line graphs, scatter plots • Find one or two particular points • Compare different points • Put points in order • Look for patterns—increase, decrease, etc. • See how one variable affects another

  7. Data interpretation • Always know what the numbers represent • Look at labels, units, scale, headings • Go only to the graph or table directed in the question • DON’T READ UNLESS YOU HAVE TO

  8. Specific CRS Skills • IOD 201: Select a single piece of data from a simple data presentation • IOD 202: Identify basic features of a table, graph, or diagram • IOD 301: Select 2 or more pieces of data from a simple data presentation • IOD 302: Understand basic scientific terminology • IOD 303: Find basic information in a brief body of text • IOD 304: Determine how the value of one variable changes as the value of another variable changes • IOD 401: Select data from a complex data presentation • IOD 402: Compare or combine data from a simple data presentation • IOD 403: Translate information into a table, graph, or diagram

  9. Research summaries Descriptions of experiments Usually includes a series of experiments with some variable changed from one to another Includes data (graphs or tables), usually numbered to go with experiments (Table 1 or Figure 1 goes with experiment 1, etc.) • More data interpretation • Understand how variables were changed in experiments and the effect that had • Predict outcomes, make conclusions

  10. Research summaries • Still read only when you have to • Include reading intro at top of passage • Look only at experiment (with its figure and/or table) directed to • Know what the numbers represent • Look for patterns within trials and between trials, identify variables and how they are changed between experiments

  11. CRS Skills • SIN 301 and 401: Understand the methods and tools used in experiments • SIN 402: Understand a simple experimental design • SIN 403: Identify a control in an experiment • SIN 404 Identify similarities and differences between experiments

  12. Conflicting viewpoints Passage that includes the beliefs of more than one scientist, or sometimes more than one student scientist • Find similarities and differences in what the scientists believe • Match evidence with a particular scientist’s position • Identify how particular evidence would strengthen or weaken a scientist’s position

  13. Conflicting viewpoints • You have to read! • Do this one last—takes the most time and has the fewest questions • Read into part too • Annotate for main differences, main similarities

  14. CRS Skills • EMI 401: Select a simple hypothesis, prediction, or conclusion that is supported by a data presentation or model • EMI 402: Identify key issues or assumptions in a model
