Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
Mixtures hide useful things — separation reveals them.
Most things around us are mixtures, not pure substances. Separating them gives us usable, safe and valuable components.
↳ Separation turns a mixed, often unusable substance into clean, useful parts.
One thing or many things — that's the difference.
Separation methods work because the parts of a mixture keep their own properties.
↳ Mixtures can be separated by physical methods; pure substances cannot be split this way.
Pick it out or beat it out.
↳ Handpicking suits few, visible impurities; threshing separates grain from stalks.
Separation of substances is the process of dividing a mixture into its useful components using methods suited to the nature of the mixture. This chapter covers techniques like handpicking, threshing, winnowing, sieving,…

18 questions laddered from warm-up to topper-level, each with an explanation. A taste:
A student says that separating salt from salt water changes the salt into a new substance. Is the student correct?
BeginnerNo, separation only changes arrangement, not the substance.
Separation is a physical process. It pulls components apart without changing what they are chemically, so the salt remains salt.
Which property difference is used in winnowing?
BeginnerDifference in weight
Winnowing uses moving air to blow away lighter husk while heavier grain falls straight down, so it depends on a difference in weight.
A farmer has dried stalks with grain still attached. Which method should he use first to free the grain?
BeginnerThreshing
Threshing is beating the dried stalks to separate grain from the stalk. Winnowing comes after to remove husk.
Which of these is the liquid that passes through filter paper?
BeginnerFiltrate
The liquid that passes through the filter is called the filtrate. The solid left on the paper is the residue.
