Lesson on haze or air pollution

Demonstration set of haze/ air pollution

Creating haze in a beaker.
1. Measure and prepare aluminium foil to cover beaker.
2. Light up wooden splint and drop it into a beaker.
3. Cover with aluminium foil.
4. Place ice on it.

Possible extension:
Use white paper towel to wipe the inner surface. Students will be able to observe very fine soot

Possible changes, use leaves and soil as a close set-up to forest. But didn’t work too well when I tried. Leaves must be really dry to burn/catch fire.
