About this activity
A clean white nanotech lab in soft blue light. A hovering lens drone dives from everyday samples on their trays (a balloon of air, a spoon of table salt, a gold ring, tap water) down to their particles, then into one particle. Students predict from the outside look, dive in, and sort each sample by what the particles show: pure substance or mixture, then element or compound.
What students learn
- Use the particle theory to tell a pure substance (one kind of particle) from a mixture (two or more kinds of particles mixed, not joined) (C2.2)
- Classify a pure substance as an element (one kind of atom, single, packed or joined) or a compound (two or more kinds of atoms joined in a fixed ratio) (C2.8)
- Trust the particle view over the outside look: air, tap water and a gold ring look like one plain thing but are mixtures
- In a solid, tell one repeating pattern of joined atoms (a pure substance) from different atoms scattered at random (an alloy, a mixture)
