19. Review: 1. How can we separate mixtures using a magnet?

20. Now that you already know how mixtures can be separated using a magnet. Let’s have an enrichment of our lesson.

21. Look around you, which objects do you think are attracted to a magnet?

22. Components of mixtures can be separated in many ways. The method that is being used usually depends on the type of mixture. Metal and non- metal objects can be separated by using a magnet. There is no chemical reaction involved in the separation of components.

23. Metals which are made up alloy, nickel, or cobalt are easily attracted to the magnet, while non-metals are not. Iron fillings, thumb tacks, staple wire, pins, coins, and needle are some common examples of objects that are attracted to the magnet. When they mixed with non-metals, these could be separated by magnet.

24. Choose from the word box the mixtures that can be separated by magnet.

25. What activity in our community where magnetic separation is applicable?

26. Complete the statement The most important concept that we discussed today was __________

27. Rose wants to remove the staple wires on the rice that she will be cooking. Using her knowledge on the process of separating mixtures she is using magnet to repel the staple wire from the rice. Questions: 1. Do you think Andrea Rose will be successful in her plan? 2. How would you describe the process of separating mixture through magnet? 3. An object that has the ability to attract the other substance is called 4. In the given situation, what is considered as the magnetic object? 5. Since rice does not repel with the magnet, what kind of substance is it?

28. List down five (5) materials found in your home that can be attracted to magnets. Additional activity

29. Comparing Techniques in Separating Mixtures Quarter 1 Week 6 – Day 3 SCIENCE 6 DAY 1
