1. BENEFITS OF SEPARATING MIXTURES

2. OBJECTIVES: Identify the benefits of separating mixtures. Describe different processes of separating mixtures. Value the importance of separating mixtures in addressing important environmental issues .

3. REVIEW: STAND FOR TRUTH Direction: Stand up if you think the sentence used the correct technique in separating mixtures. Filtration is the technique used to separate solid and liquid mixtures. ANSWER: TRUE b. Sieving is the technique used to separate 2 solids that vary in their sizes. ANSWER: TRUE The evaporation technique uses heat as the main component in separating soluble solids from liquid. ANSWER: TRUE

4. Magnetism is the technique used to separate monggo and rice. ANSWER: FALSE b. Decantation technique is the process used to separate coffee granules form hot water. ANSWER: FALSE c. Handpicking is the most suitable technique to separate pebbles and rice grains. ANSWER: TRUE

5. MOTIVATION: GUESS ME Magnetism

6. MOTIVATION: GUESS ME HAND PICKING

7. MOTIVATION: GUESS ME FILTRATION/ FILTERING

8. MOTIVATION: GUESS ME SIEVING

9. MOTIVATION: GUESS ME EVAPORATION

10. WHY DO WE NEED TO SEPARATE SOME MIXTURES IN OUR ENVIRONMENT? ANSWER: BECAUSE SOME OF THE MIXTURES IN OUR ENVIRONMENT DO NOT APPEAR AS PURE THAT IS WHY WE NEED TO SEPARATE THEM TO GET THE DESIRED COMPONENT.

11. Why do we need to use magnets to separate mixtures of metals and non metals Because it will be easier to remove metals from the mixture.

12. Why filtration is important in our daily lives. We can use this to separate some liquid from solid mixtures. Just like coffee granules and hot water

13. How can sieving help us separate lumped flour from cake flour . It is easier for our mother to remove the lumpy flour from the good ones.

14. How evaporation beneficial in our lives. We can make sugar crystals and salt through evaporation.

16. I learned that ….. __________________has different benefits. Many components found in the nature aren’t in their pure form but are found as parts of mixtures. It is important to ___________ mixtures in our daily activities in order to get the needed component. Examples are: 1. Segregating monggo from needles can be separated through the use of _____________. 2. Filtering the water from the faucet will give us __________ water. 3. We can make salt from seawater through the process of ______________. Separating Mixtures Separate m agnets clean e vaporation Clean magnets separate evaporation S eparating mixture

17. Separating mixtures is not important in our daily lives. ANSWER: FALSE b. The use of magnets help us easily separate metals from nonmetals. ANSWER: TRUE To avoid discoloration of clothes, we separate the colored from the white clothes through decantation. ANSWER: FALSE

18. D. We can obtain salt by the process of filtration. ANSWER: FALSE e . We can separate unwanted components from the water by filtration. ANSWER: TRUE
