Identify some of the assumptions in secondary sources, and decide which variable to change and measure for a fair test.
The BC Science K–9 (redesigned curriculum) outcome (Curricular competencies) for Grade 6 says: “Identify some of the assumptions in secondary sources, and decide which variable to change and measure for a fair test.” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: BC Science K–9 (redesigned curriculum).
Test the Claim: Science Facts, Myths and AI Answers Grades 5–7
Sayings, ads, forum posts and AI chatbot answers all sound sure of themselves. Students put popular claims to a real hands-on test, grade the answers, and learn how to decide which sources deserve their trust.
- Does salt make water boil faster? 45–60 min
Students test two kitchen claims at once: that a watched pot never boils, and an AI-style answer saying salt makes water boil faster. They time plain and salted water in a teacher-run kettle, then write a claim, evidence and reasoning about what really happened.
- Is that AI answer true? 50–60 min
Students get three printed AI chatbot answers to science questions, write a test for each, and run the two that fit in one class: dropping a full and an empty bottle, and melting ice in fresh and salty water. They grade each answer and explain why a confident answer still has to be checked.
- Which source should we trust? 50–60 min
Students compare four sources making the same claim about a paper towel: a study summary, an ad, a forum post and an AI chatbot answer. They rate the evidence behind each, then run a fair absorbency test to settle the question with their own data.
