What This Standard Means

What Students Need to Do

Students find several sources about a chemistry claim. They check who wrote each one, whether its numbers are accurate, who might benefit from the claim, and whether its conclusion fits the evidence.

What Mastery Looks Like

A student can compare an alkaline-water ad with test results from another source. They can point out a sales interest, check a pH claim, and explain why a pH reading alone does not prove a health claim.

Common Misconceptions

Students may treat a polished website or a .org address as proof that a claim is true. They may also accept a health claim based only on pH data, or reject useful data just because a company published it.

How to Assess It

Give students an alkaline-water ad and a lab test of the same brand, both with pH readings. Ask them to check the ad's pH claim, name a possible bias, and explain whether the data support its health claim.

Lesson moves

Ways to Teach It

  1. Give pairs printed source cards with authors, pH data, dates, and sponsors; have them sort the cards by evidence quality and explain their ranking.

  2. Ask students to write: Does a pH reading prove alkaline water improves health? Require them to say what the reading does show.

  3. Play source detective with four printed articles; teams earn points for finding an author, a data source, a sponsor, and an unsupported claim.

  4. Bring an alkaline-water bottle label and a test report for that brand; students compare pH figures and circle claims the test cannot support.
