Question 1

List the seven report components used in this lesson.

In a synthetic spinner dataset, model B at 5 cm wing length has descent times of 1.7, 1.8 and 1.9 s. Calculate its mean descent time.

At each wing length, models A and B are built separately and each is dropped three times. State the number of independent builds at each length.

Teacher answer key — 3 questions

Model responses identify the essential ideas. Accept scientifically correct alternatives that address the question; wording need not match exactly.

Observation/question, hypothesis, method/variables/safety, raw data/provenance, analysis/graph, conclusion/evaluation, follow-up. Equivalent coherent headings are acceptable.
(1.7 + 1.8 + 1.9)/3 = 1.8 s.
Two, each with three repeated drops.
