About this activity
Two teams test 13 mystery mixtures from the kitchen, the garage and the lab with a brass lens on their phones, call each one homogeneous or heterogeneous from the evidence, then name it as a solution or a mechanical mixture with the particle view.
What students learn
- Distinguish homogeneous mixtures (solutions) from heterogeneous mixtures (mechanical mixtures) by examining them up close
- Use evidence from a lens and from letting a mixture sit, not colour, state or a first look, to classify a mixture
- Explain each mixture with the particle theory: evenly mixed particles in a solution, clumps of different particles in a mechanical mixture
