How we explain it
Children can open this short lesson before they practice.
- Ethos appeals to credibility (trust me, I’m an expert). Pathos appeals to emotion. Logos appeals to logic, facts and numbers.
- Fallacies are weak reasoning: bandwagon (everyone does it), false cause, slippery slope (one step leads to disaster).
- The strongest evidence is specific, relevant and from a reliable source.
Example: A speaker mentions years of coaching experience so the audience will trust their advice. Which appeal is this? The speaker is building trust, not using feelings or numbers. Trust in the speaker is credibility. Answer: Ethos (credibility)

Sample questions
A taste of this unit. In the app, questions change every time and get easier or harder to match your child.

Which sentence is a claim, not evidence?
- A survey found that 62% of residents would bike more if lanes were safer.
- Bike traffic on Elm Street doubled after a lane was added.
- The city's two bike lanes each carry about 800 riders a day.
