Students explore acids and bases — from lemon juice to bleach — and the pH scale that measures them, learning what makes a substance acidic or basic and why the scale runs from 0 to 14.
Students will be able to…
Lemon juice, soap, water, and bleach — what invisible property separates them, and how can one scale from 0 to 14 capture it?
Project this and slide across the pH scale. Watch the color, category, and a real example change from strong acid to strong base.
Tap any phase to open the teacher moves and student actions.
