Lesson details
Key learning points
- Filtration is a technique used to separate insoluble substances from a mixture with a liquid.
- Separation in filtration occurs due to the difference in size of particles.
- The terms 'filtrate' and 'residue' describe the components separated by the process of filtration.
Common misconception
A funnel is the same as a filter.
A funnel streamlines movement, while a filter separates materials. Use everyday examples to highlight the difference, e.g. an oil funnel vs. an oil filter, or a coffee funnel vs. a coffee filter.
