Instructional Ideas

• Use as a review of the hydroxide precipitates of aqueous metal ions
• Includes only limited instructions, so ensure all pupils understand how to complete the puzzles before assigning

Classroom Considerations

• Relies on prior knowledge of metal ions, their formulas, the color of precipitate, and the precipitate formed

Pros

• Offers online, timed version and a paper version depending on the needs of your learners
• Reviews metal ion names and formulas as part of the activity to reinforce the content

Cons

• None
