Metals and Acids — Interactive Lesson (Ages 11–14)

Drop magnesium into acid and it fizzes; drop copper in and nothing happens. Why? This 18-slide interactive lesson on metals and acids takes pupils from first ideas to exam-style explanations, with 10 self-marking activities and nothing to prepare beforehand.

Teaching Metals and Acids in KS3 Science

Pupils describe the reaction metal + acid → salt + hydrogen, name chloride, sulfate and nitrate salts from the acid used, and carry out the squeaky pop test for hydrogen. They use observations of magnesium, zinc, iron and copper to put metals in order of reactivity and plan a fair, safe experiment.

What Pupils Will Learn

• Describe what happens when metals react with acids.
• Name the salts made by different acids.
• Describe the test for hydrogen.
• Use observations to put metals in order of reactivity.
• Describe how to carry out the experiment safely.
