Introduction: Prior to beginning the lesson: (1) Cut out and laminate Vocabulary Cards for display in the classroom. (Allow 30-35 minutes for instruction time.) Group Size: Whole class Learning Objectives: Students will be able to:
Identify and explain the characteristics of objects that are magnetic.
Materials: Vocabulary Cards (see attachment), Are you Magnetic? (from Lesson #2), chart paper, magnets, paper clip, small piece of aluminum foil, small piece of copper wire, glass marble, wood match, brass fastener, dime, soft drink can, needle, small piece of steel wool, small piece of leather Procedures:
Tell Students: I want you to think about the science experiment we did yesterday. What objects attracted the magnet? What objects did not attract the magnet? Call on students to list the objects.
Display the objects from the previous day’s experiment at the front of the room. Call on students to come up and put the objects into two groups: Magnetic and Not Magnetic.
Display chart paper and divide it into two columns. Label the columns “Magnetic” and “Not Magnetic.” Call on students to come up and write the name of each object under the correct category.
Tell students: Let’s think about just the objects that are magnetic. Remember, they are magnetic because they were attracted to the magnet. What do these objects all have in common? Call on students for ideas.
Ask students: What is the one thing they all have in common? Guide students to answer they are metal.
Point out to student that the aluminum foil is metal but it did not attract the magnet. Explain to students: Most metal is magnetic but some metal, like the foil, is not.
Display vocabulary cards "metal" and "non-metal". Give students a chance to explain each word.
Redistribute Are you Magnetic? to students and give them time to answer the final question.
Modifications: For students with special needs, allow them to dictate answers for the teacher to record, or provide one-on-one assistance for students’ to write answers. Assessment: Monitor students’ participation for understanding. Circulate classroom and ensure students are writing correct answers.
