Mixture Separator

Learning fit

Labels show who asserted each claim.

A mixture-separation lab for ages 11-14. Three mixtures (sand + iron filings + salt + water; beach sand + shells + water; dissolved salt water) are separated by choosing tools in the right order (magnet, filter, evaporation dish, strainer), with animated results, collection jars, and specific why-it-fails feedback — including the key insight that dissolved salt passes through filter paper. Insight cards frame separation as using physical properties with no chemical change, and distillation is introduced for recovering pure water.
