2 Classroom Procedure: 1. Distribute the magnets to students. Ask students if they know what they are, how they work, etc. (The more magnets per student, the better.) 2. Allow for responses and discussion. Allow students to experiment with the attraction and repelling of the magnets with another student. 3. Distribute items to be passed around to determine if the object is attracted to the magnet. On a separate sheet of paper students will list each object and write YE or O to the question: Is the object attracted to the magnet? 4. Once completed, distribute the Magnets content page. Read and review the information with the students. Emphasize the vocabulary. 5. Distribute the Activity page. Review the instructions. Allow sufficient time for its completion. Check and review with the class. Ask student volunteers to share the magnets they drew showing repelling and attracting. 6. Distribute the Practice page. Check and review with the students. Check for understanding. The soda can, as most are, is aluminum. 7. Distribute the Homework page. The next day, check and review the page with the students. 8. In closing, tell students to draw a picture showing how using magnets for a new invention, which would help them do something around their home or at school. Encourage students to be creative. Allow volunteers to share their invention. Teacher otes This is a very basic introduction to magnets and basic vocabulary. It is recommended the students have access to magnets, allowing the students to attract and repel the poles, as well as to experiment with the different materials attracted to magnets. Do not include too much of the technical concepts of magnetism; that information will be better taught in the later grades. Approximate Grade Level: 1 3 Objectives: The students will be able to define the term magnet, identify the poles of a magnet, and how the poles react to each other, and to other materials. Common Core tate tandards: CC.ELA-Literacy.RI.1.2 CC.ELA-Literacy.RI.1.7 CC.ELA-Literacy.RI.2.2 CC.ELA-Literacy.RI.2.7 CC.ELA-Literacy.RI.3.2 CC.ELA-Literacy.RI.3.7 Class essions (45 minutes): 1-2 class sessions Teaching Materials/Worksheets: Magnets content page, Activity page, Practice page, Homework page tudent upplies: magnets, handouts Prepare Ahead of Time: Enough magnets for every student or at least one for each pair of students. Materials or items students can use to identify what can be attracted to magnets, and what is not attracted to magnets. Additional Resources: COTET: WORKHEET: VIDEO: (6 min) (5 min) (3 min) (12 minw/activities) Options for Lesson: tudents may work in pairs for the activity, or the activity can be done as a class. pend extra time on the lesson to give students more opportunities to use the magnets, and play with them. Allow students to vote on their favorite invention. Plan ahead and ask parents of students for old motors or other objects containing magnets. Allow older students to take apart the items to find the magnets. 1

3 Magnets Do you know what these are? If you said magnets, you are right. Magnets are used in many places and for many things. Magnets are used in speakers, computers, motors, door bells, telephones, compasses, tools, on doors, by recycling centers, hospitals, and many other places. You probably used a magnet without even knowing it. Magnets by themselves are easy to use, safe, and fun. A magnet is a piece of metal, usually iron or steel, that is able to attract certain other metals. The area surrounding a magnet is called a magnetic field, shown in the picture below. Pieces of metal like iron or steel can be pulled to a magnet, meaning it is attracted to the magnet. The metal will stick like glue to the magnet. 2

4 orth and outh Poles There are two ends of each magnet. One end is called the north pole and the other end is called the south pole. The north and south poles of magnets are attracted to each other and will be pulled towards each other. The same poles of two magnets will push apart, or repel each other. ATTRACT (Pull together) REPEL (Push apart) REPEL (Push apart) Remember, different poles will attract, and the same poles will repel. 3

7 Homework ame Date Answer each question or fill in the blank. 1. What does the letter mean on a magnet? 2. What does the letter mean on a magnet? 3. When two magnets are to each other they pull towards each other and will stick together. 4. When two magnets they push away from each other and will not stick to each other. 5. The area around a magnet is called the magnetic. 6. List seven places where magnets are used: a. b. c. d. e. f. g. 7. A is a piece of metal, usually iron or steel, that is able to attract certain other metals. 6
