Chao 1/25

            18 days until I can finally gain some freedom with an automobile license. The countdown has officially begun.
            Moving on, today in Physics, we had a very interesting, hands-on day. We continued to finish up the little energy labs and stations that Coats-Haan set up around the room. I had to sport goggles because those green, cool glasses were not suitable for another pair of glasses that I have to mandatorily wear on my face. I felt quite sad looking like the average Chemistry student with goggle marks deeply embedded within my forehead.
Groups straddled from table to table, shaking plastics cans of sand, bending wire back and forth, spinning rotors with just two sticks, making matchstick rockets, and testing to see if lemons can really light up your home, among 14 different stations. We slowly filled out the worksheets regarding these energy labs from our lab manual. I believe it is page 107.
But sadly, all of the fun came to an end at 9:15 when the bell rang. If you didn’t finish getting your energy labs done, instructions are to complete the two worksheets on your own.
Additional homework, which is important to complete, is the 6.1 and 6.2 Guided Reading. A book, a pencil, and Internet access is needed. Oh, and a brain might be important too.
Question of the Day: What was your favorite station? What were the energy transformations at that station?
The station that I found to be my favorite was the station with the candles. After lighting a match and lighting a candle, we blew the candle out and immediately stuck the lit match into the smoke streak, which relit the candle! It was very cool.
The energy transformation that occurred at that station, I think, was thermal energy (caused from the friction of the match rubbing onto the box to ignite) converting to light energy (the flame). When the match was stuck onto the candle, I suppose the potential energy of the candle wick converted to thermal energy and light energy when the flame was brought to it. I’m not sure though.

The dial on the far right of an electric meter reads 9.  The dial next to it appears to be just on the 8.  Is its value 7, 8 or 9?  Justify your answer.

Armour 1/23

Today in physics we did multiple activities. The first thing we did was we viewed the new blog schedule. Next we were given our team farewells and a new blue make up policy sheet. After we filled out the farewells and gave them back to the appropriate person, we changed seats. Then Coats-Haan went over the new project where we have a choice to build a windmill or construct a Rube Goldberg machine. Lastly we made towers out of paper with one sheet of white paper and glue. Trevor Harrison’s group had the highest tower with 77.5 cm.
Q.O.D. What has to happen for you to do work?
There must be a displacement and a force must cause the displacement.
