Soluble vs Insoluble: Lesson & Game — Interactive Lesson with Sorting Game

A complete mini-lesson on dissolving, start to finish in 10-15 minutes. Two short explainer slides introduce what soluble and insoluble actually mean, then students put it into practice across a 3-round sorting game that gets progressively harder.

Whats inside

• Explainer slides: “What does soluble mean?” and “What does insoluble mean?”
• Round 1 — The kitchen cupboard (everyday substances: salt, sugar, sand, flour, coffee, pepper, vinegar, chalk)
• Round 2 — Trickier substances (bath salts, oil, food dye, rice, baking soda, plastic beads, wood shavings)
• Round 3 — In the lab (copper sulfate, iron filings, potassium nitrate)
• 18 substances in total, with instant feedback throughout

Why it works

• Self-contained — explains the concept before testing it, no separate teaching needed first
• Difficulty ramps up round by round, so it stretches stronger students without losing beginners
• No setup, works on any device with a browser
