Magnets & Motors
Lesson 8
Making Magnets With Electricity
Students learn that a coil of wire, with electricity flowing through it, has magnetic poles.
3. Lesson set up and Management
Questioning: Generate questions that can be answered through scientific investigations (IN01.2.1.1).
Planning and Conducting Investigations: Plan, conduct, and evaluate scientific investigations, using appropriate equipment, mathematics, and safety procedures (IN02.2.1.2).
Explaining: Use evidence from scientific investigations to think critically and logically to develop descriptions, explanations, and predictions (INO3 2.1.3).
An electric current moving through a wire produces electricity.
A steel bolt placed inside a coil of wire conducting an electric current, increases the strength of the electromagnet.
3. Lesson set up and Management
Materials:
Have materials in numbered baggies ahead of time. If any wires were damaged in the last lesson, then you may need to strip them again.
Student Management:
Student pairs will discuss what they have learned so far. Again, although this lesson is written to be done individually, the lesson can also be done in pairs.
This might be a good time to make sure that you are asking open-ended type questions. One example of such a question is, “Where do you think magnets come from?”
Writing:
Students draw and label pictures in their science notebooks showing how electricity can make magnetism.
