Exercise a healthy, informed skepticism and use scientific knowledge and findings to evaluate claims in secondary sources (an early start on Grade 7).
The BC Science K–9 (redesigned curriculum) outcome (Curricular competencies) for Grade 7 says: “Exercise a healthy, informed skepticism and use scientific knowledge and findings to evaluate claims in secondary sources (an early start on Grade 7).” 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.
