TEKS 4.7(D)
Worksheet Answer Keys (Case Files 101 & 202)
Case 101 Part 1 (Fluff Filter):
Statement A is an opinion ("most adorable creatures") and does not convey scientific fact.
Statement B is an unrelated minor detail not central to how turtles navigate.
Case 101 Part 2 (Exemplar Summary):
"Loggerhead sea turtles migrate thousands of miles across the Atlantic Ocean. They navigate without getting lost by sensing Earth's invisible magnetic fields like an internal compass."
Case 202 Task A (Independent Exemplar Summary):
"Southern flying squirrels glide through the forest canopy using a thin, fur-covered membrane of skin stretched between their limbs. By adjusting this skin and steering with their tail, they find food and escape danger."
Case 202 Task B (Multiple Choice Item):
Correct Answer: B. Captures both the mechanism (skin membrane) and purpose (steering to safety/food) in logical order without fluff.
Distractor analysis:A contains personal opinions ("coolest", "amazing"). C focuses solely on an isolated detail and misrepresents hiding behind bark. D is an isolated definition without the overall function.
Exit Ticket Master Key
Question 1: Best Summary
Correct Answer: B
Captures the primary survival mechanism (moisture from seeds) and daytime behavioral adaptation (cool burrows) logically and factually.
Question 2: Personal Opinion
"These little jumpers are much smarter than ordinary rats."
Key cue words: "smarter" represents a value judgment/opinion rather than empirical text evidence.
