9. Separating mixture by using a magnet can be used to separate mixtures when one of its components is magnetic like iron filings and small nails. Mechanical separation involves the use of tools such as magnets, forceps, and sieves to separate solids that are mixed. The magnetic material is attracted by the magnet, leaving the non-magnetic material behind. The use of magnet to separate metallic materials is useful in many ways. Here are some of the benefits of separating mixtures using magnets. Magnets are used in food processing industries for separating small metallic pieces from flour, grains etc. to avoid metallic contamination Magnets are used to separate mixture of iron filling and Sulphur Magnets are used to separate iron nails from sawdust. They are also used to sort out magnetic and non-magnetic materials from scraps and junks.   • Abstraction

21. Another way of separating mixtures is through evaporation. Applying heat will cause the liquid in a mixture to evaporate leaving the other component/ substance behind. Evaporation is a technique used to separate homogeneous mixtures where there is one or more dissolved substance. The method drives off the liquid components from the solid components. The process typically involves heating the mixture until liquid evaporates into water vapor. There are many ways by which evaporation take place in our community or at home which are beneficial to us. Salt Making Sugar Refinement -Salt and sugar crystals obtained either from a natural process or from an industrial process, evaporation is used Evaporation is used in producing patis (fish sauce). The cooling of hot milk or tea is caused by the evaporation of hot molecules on the surface; thus, it becomes just enough for drinking. • B. Abstraction

22. When cooking rice or heating foods , evaporation takes place that caused changes in the materials. The evaporation process is used in food processing industries to process milk, pasta, and other concentrates. Another field in which evaporators are widely used is waste management . Waste management providers rely on them to treat effluents, or wastewater, from various plants, including distilleries, grain mills, textile plants, chemical reactors, and storage tanks. Evaporators are also used in oil fields to separate water and various other compounds from crude oil. • B. Abstraction

36. What specific activities in School/ Experiments, Home/ Kitchen and Laboratory that separate mixtures through decantation? Can you give more examples of activities in your community that separates mixtures through decantation? Do you think Decantation is important in our daily life? Why or why not? • Analysis

37. • Abstraction Decantation is the process of separation of liquid from solid and other immiscible (non-mixing) liquids, by removing the liquid layer at the top from the layer of solid or liquid below. In the process of decantation, the mixture is left undisturbed. When the components are separated, the less dense substance could be removed by scooping using a spoon or it can be removed by slowly pouring out the less-dense substance. The following are the activities in the community where decantation as a process of separating mixture is beneficial to us. In school/experiments Separation of oil and water Separation of gasoline/ kerosene and water Separation of muddy water Separation of metallic materials from sand and silt.

51. Why did you choose these pictures? Why do you think centrifugation is the right process to be used in separating these mixtures? Do you think centrifugation is important in our daily life? Why? • Analysis

52. • Abstraction Another way of separating mixtures is through Centrifugation. It is a way of speeding up the process of sedimentation. A centrifuge, found in a laboratory, consists of many test tubes spinning at a high speed which inevitably forces the insoluble substance to the bottom quicker. A washing machine is a good example of this process. It spins quickly and water flies out through the holes in the sides and the clothes stay in the washing machine. Here some of the benefits of separating mixtures through centrifugation. Separation of blood components Separation of suspended solids from solutions, example separation of clay particles from water Skimmed milk can be obtained from whole milk with the help of the process centrifugation Getting sugar from sugarcane juice/ sugar production Stabilization and clarification of wine The centrifugation of contaminated water allows to extract dense substances inside Production of beverages, juices, coffee, tea, beer, soy milk, cheese
