Students learned about electromagnets. They viewed how an object made of iron, nickel, steel or cobalt can become a magnet if you apply electrical energy through a wire that is coiled around it. Connor mentioned, "I've seen something like that on TV. There was a junkyard and a machine was picking cars up and dropping them into another place." To ensure students got the concept of an electromagnet, it as placed near a compass thus moving the needle indicating a magnet was present. The class also got to see the difference between a parallel circuit and a series circuit. The parallel circuit (above) is complex because every bulb has it's own pathway. The series circuit (below) has only one path. Because of this, the bulbs in a series circuit were dimly AND if you remove a bulb, all of the other bulbs would not work. They were sharing the circuit in a series circuit. Jill stated, "My holiday lights do the same thing." In the parallel circuit, students noticed that all bulbs produced the same amount of light AND when one was removed, they continued to be lit. "This is like the light in my house", noticed Daniel. Parallel circuits have multiple pathways.
I hope you enjoy learning how the garden changes throughout the school year.
