Today in class we made closed circuits to complete our Conductor/Insulator Lab. I loved seeing the kids expressions and hearing their squeals as they lit their light bulbs for the first time! Here is an example of a completed closed circuit.
After students completed their circuits, they worked on their conductor and insulator page in their notebook.
Here are some pictures of our lab groups. I was so impressed with how hard they worked, and how fast they put their circuits together!!
Today we made electromagnets in class. I loved seeing our groups work together and hearing their squeals as their electromagnets started becoming magnetic.
Background – Electromagnets are different from regular magnets in a few ways. They can be turned on and off and their strength can be controlled. This makes them useful in many different technologies like headphones, washing machines, and electric motors.
Here are some pictures of groups with their electromagnets.
These students were the first in fourth period to make their electromagnet. 🙂
