Free sample of the ten-reading pack. Two complete readings from Real-World Science Reading + CER Questions: 10 No-Prep High School Sub Plans, each with its question page, plus the answer key for both.

What you get

• Reading 1 - The Bird That Was the First Gas Alarm (science and engineering, measurement). Students work out why a living indicator was used before electronic sensors could be trusted, and where that design still fails.

• Reading 2 - Nine Hundred People, None of Them Like You (nature of science, sampling and bias). A clinical-trial design problem students can actually argue about.

• Each reading: a 410-500 word passage, four vocabulary words, four short questions, one Claim-Evidence-Reasoning prompt.

• Answer key naming the paragraph each short answer comes from, and what earns credit on the open ones.

How teachers use it: print one reading with its question page as a sub plan, or use it as the week's CER writing warm-up. No lab, no video, no student login.

The full pack adds eight more readings (gene editing, invasive fish, urban heat islands, mouse trials, computer-found antibiotics, soil microbiology, false positives in screening, the vaccine cold chain), the complete answer key, editable Word files in Letter and A4, and a 60-slide deck for projecting the same passages.
