Science Lab: Electromagnets and Circuits
Lesson Outline
Christopher started his lab today by reading about an electromagnet because this was the activity for the lab. Christopher explained the important facts and I helped to transcribe it into his notebook. He told me that an electromagnet is be made by wrapping a wire around a nail and attaching it to a battery. Christopher was introduced to the materials that he needed. He began to wrap the wire around the nail. Then I helped him attach it to the battery terminals. Christopher tried to see if the nail was magnetized enough to pick up paper clips. With only 6 wraps of wire, the nail could not hold any paper clips. Next, Christopher wrapped the wire around the nail six more times. This time, when we attached it to the terminals of the battery, the nail could hold four paper clips. Christopher continued to wrap wire around the nail in intervals of six wire wraps. Each time, the wire was then connected to the two terminals of the battery and the nail was tested to see how much magnetism it had by attempting to see how many paper clips it could hold. Christopher found that the more wire wraps he did, the more paper clips the nail could hold when attached to the battery. Christopher explained this conclusion to me and I wrote it in his notebook. The second experiment that Christopher conducted was the making of a circuit. He was introduced to all of the materials he would need. Christopher examined the socket, the bulb, and the wires with little gator teeth. He began to attach the wire to the terminal on the battery and then to the socket. The next wire, Christopher attached from the socket to the other side of the battery. Christopher was happy to see that he made the light bulb turn on. The second part of this experiment was to include a switch in the circuit. Christopher needed some help to visualize how the circuit would be constructed. He then could see that the wire would go from the socket to the switch and that another wire was needed to go from the switch to the negative terminal on the battery. Christopher was successful in making the light bulb go off and on by opening and closing the circuit. To complete the assignment, Christopher drew a diagram showing how he made a circuit from a battery to a socket with a bulb, to a switch, and back to the battery. This was a great experience for Christopher.

Lesson Comments
Christopher did a good job of working on the electromagnet. He complained about being tired throughout the lesson, but he kept on working. He worked on making the circuit. The concept was difficult for him and he had to redo it three times to understand why the wires are connected from the battery, through the socket, and back to the battery. Christopher is working on catching up in science.
