Overload...

Well, it's been awhile since we've talked about these things, but I just found what I think is the circuit breaker for my apartment. At first I thought they were fuses, but they don't seem to have anything that is easily replaced and the switches go on and off. These switches turn off when the current going through the wires is too high. This is to protect the house from possible fires that could occur when too much current goes through a wire and burns it up. There are many switches because each one is in charge of the current flowing to a different area. I think this means that the system is in a parallel because that way one switch going off won't affect the rest. (Luckily, we've only had to use the circuit breaker once from what I can remember.)

wonders on a refrigerator

Well this lesson we're learning about magnets, which is something I never thought I would be able to relate to physics. In fact, before this chapter, I never even thought about why magnets are able to hold photos down by sticking onto things such as a refrigerator. The magnet has a north pole and a south pole (which are the front and back sides of it) and each pole is attracted to its opposite. This is what allows magnets to stick together at times. However, magnets can also stick to certain materials (such as metals) even when the objects are not magnetized. However, just like in the lab, there is a certain place where the two poles meet that does not allow for other object to be attracted. This place makes it easier to distinguish between magnets and objects that can stick to magnets. It's kind of funny how just going for a late night snack can remind me of physics.
