Grade 6-Q1-SCIENCE-LAS 2 SCIENCE 6 Name: ______________________________________ Grade:______________________________________ Date: ____________________ Section: ___________________ Quarter: 1 Week: 2 LAS No. 2 MELC(s: 1. describe the different techniques in separating mixtures (S6MT-Id-f-2) _____________________________________________________________________________________ • Mixtures can be separated using different techniques such as picking, winnowing, using magnet, decantation, filtration, sieving and evaporation. • Picking is the separation of large components of a mixture by picking them out through the hands. These components can be classified according physical characteristics like size, shape, color and texture. • Winnowing is done by separating heavy and light components of a mixture through a device (winnower) and by wind or by blowing. • Using magnet is done by separating the metallic and non-metallic components of a mixture. • Sedimentation is the process of allowing the solid precipitate of a mixture to settle down at the bottom, leaving an upper liquid layer. • Decantation is done by allowing the solution to settle at the bottom of the container and pouring off the particle-free part of the liquid. • Filtration is used for separating the undissolved solids from liquids by using a filter. • Sieving is done by allowing the dry mixture with different sizes to pass through a device with tiny holes (sieve). • Evaporation is the separation of components by heating a solution until the liquids turn to gases leaving the solids behind. Direction: Identify the different separation set up. Below it, write a short description about the picture.
