2/28 Gaitan


Today, since our class was farther behind than most classes, we finished the Section 1 lab, and a few groups may have started the Section 2 lab.  If any groups had completed the Section 1 homework, they were to return it in today, and if not, they will turn it in tomorrow, on a separate sheet of paper.  During the lab, our table was trying to figure out how to connect the wires to the switch and the light but was having trouble.  It was eventually pointed out to our table that we were supposed to use the clips, which is easier, and that we were the only group who needed that pointed out to them.  In the rest of the Section 1 lab, we found out more ways to make circuits, which parts of the light bulbs are conductors or insulators, and how to draw the circuit diagrams.  We did all of these exercises first to learn more about which materials conduct or insulate better, and to build upon topics that we had discussed, while performing them ourselves.  The difference between circuit diagrams, and what the model actually looks like also should have been learned today.  When a battery and a light are connected, electrons flow from the negative side of the battery through the conductor, turning the light on, and through the other end of the battery continuously unless something else interferes.  This makes a complete circuit, because the charge is passed along in a continuous circular motion.

2/28 qod

You have a battery connected to a bulb in a complete circuit.  What do you know about the flow through the circuit?

2/27 Clyde

Today, we started off the class with a quiz over electrostatics. If you studied, it wasn't particularly difficult and only took a short amount of time to complete. For the rest of the class period, we continued to work on the long-term lab concerning electric circuits, experimenting with the light bulbs and flashlights and batteries. If your group completed section 1, then you can go ahead and do the section 1 homework. Coats-Haan also walked around and asked the juniors which science they plan to take next year so that she can recommend them for that class on HAC. Anyways, if you're a junior and you haven't talked to Coats-Haan about what science class you plan on taking next year, you should go have a chat with her.

QOD: Electricity flows through the light bulb in a complete circuit with a battery and a wire attaching both the bottom and side of the light bulb to the opposite ends of the battery. The electricity flows from the battery, through the wire, and into the light bulb, going through the bottom or side into a tiny wire which we can see through the clear glass bulb, which lights up as the electricity passes through it to the other side, back down the wire, and through the battery again.

2/27 qod

How does electricity flow through the light bulb?

Today in the wonderful world of third period Physics, Mr. Ebersole checked the previous night's homework which was the ridicuously hard electrostatic problems. We then went over this homework with the key, while asking for problems to be worked out on the board by the one and only Mr. Ebersole. We were explained the new Circuit Lab and I called it "mega lab" and Mr. Ebersole said "you know what that is a good name." And I said "yeah I just came up with it", and then Coats-Haan had to ruin it and tell him Im not creative and that it was the name of our Chemistry lab last year. During class we also started working on section 1 of the Circuit Lab. We were not assigned any homework other than to study extremely hard for the extremely difficult quiz we have on Monday (02/27). So good luck everybody! 

QOD:  What is your operational definition for a circuit?

The operational definition for a circuit would be to prove that there is an actual functioning circuit. To do this, use a copper wire, a light bulb and a battery. Wrap one end of the copper wire around the light bulb , touching metal on metal. And then touch the other end of the wire to the positive or negative side of the battery and the metal part of the light bulb to the negative or positive side of the battery. And when the electric circuit is complete, with a charged battery, it will produce the light bulb to give off light.

STAY CLASSY 3RD PERIOD!
