3. Magnetism is an invisible force that can attract (or repel) certain materials, such as iron and steel. This force is called magnetic field and is created by magnets. What is magnet? Magnets are made of magnetic materials that produce a magnetic field. Magnets pull other objects made of magnetic materials towards them. They will either attracts or repel other magnets.

6. What was your score?   If you got all the answers correct, congratulations! It shows that you have a wide range of knowledge when it comes to our topic on the use of magnets. You may still review this topic and learn new things ahead.

7. If you didn’t get a high score, no worries. This module will help you learn more the concept that you may eventually use in your daily life. Study carefully this topic and you will be able to answer all the questions in the activities that lie ahead. Are you ready? You may now study Module 2.6: Separating mixtures using magnet.

8. In the separating of mixtures using magnet, you can use this abbreviation as a reference to easily identify what is magnetic materials and non-magnetic materials: Magnetic: Non-Magnetic I –IRON G - GLASS O C - COBALT P - PLASTIC A L N E A S E S - STEEL W - WOOD E A E S H N - NICKEL P - PAPER I R C O K P R L Y

9. Activity 2 Guide : Look around you. What are the things that you see? Below are some items that could see in your surroundings. I want you to go over the list and encircle the items that you think are magnetic

10.   Guide Questions:   Identify the non-magnetic materials listed above.

11. Magnetic separators are used in factories. Materials are put on a conveyor belt that is spun by magnetic wheels. As the objects are moved upside down the non-magnetic objects fall off and the magnetic ones stay on. This separation technique can also be useful in mining as it is attracted to a magnet. Moreover magnetic separator is also used in milling.

12. It removes metal species in wheat, in order to ensure safety at work. To remove metal content from wheat to protect other machines safety. And to remove metal powder mixed in flour during milling process and to ensure product purity, magnetic separation is needed before finished product packaging.

13. Guide Question: How can you separate magnetic and non-magnetic materials in a junk yard?

14. Activity 3 Guide: Title: Which material is attracted to magnet, an iron filings or a salt?   Materials : salt, iron filings, plate, magnet III. Procedure: 1. Prepare the materials needed. 2. Combine the two substances, the salt and the iron filings. 3. Separate one substance to the other substance by using magnet to attract them. 4. What do you call the process of separating substance in a mixture using magnet?

15. IV. Guided Questions: 1. Which substance is attracted to magnet? 2. What do you call this substance? 3. What is the importance of separating substance?

16. We can use magnetic separation if we want to separate heterogeneous mixtures that consist of substances attracted by magnets (iron) and substances that not (sand, wood…).

17. Activity 4 Guide : Which substance/s is attracted to magnet, staple wires, soil dust, or nails?   Materials : magnet, staple wires, soil dust, nails, magnet Procedures: 1. Prepare the materials needed. 2. Put them together in a plate. 3. Use the magnet and hold it near the mixture. 4. Observe what happen.

18. Guided questions: 1. What happen to the staple wires and nails as the magnet is near into it? 2. What happen to the soil dusts as the magnet is near into it? 3. What do you call those materials like staple wires and nails That they were attracted to magnet? 4. Can you give other substance/s that can be considered as magnetic?

19. Activity 5 Guide: Identify the following materials, magnetic or non- magnetic.

20. Activity 6 Guide: https://docs.google.com/forms/d/e/1FAIpQLSfewCEmCeP_Ibh5mIKeQQJ4jIZSJ8U1Zp_XUJZa4sxCfU82VA/viewform?usp=sf_link

21. Activity 7.1 Guide : Andrea 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.

22. 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?

23. How would you describe the process of separating mixtures through magnet? Is it useful to our daily life?

24. The learners, in their notebook, journal, or portfolio will write their personal insights about the lesson using the prompts below. I understand that ___________. I realize that ______________.
