Yet again, another exciting day of physics has elapsed. Of course, with the ending of another physics class comes a new daily scribe. That scribe happens to be me today. Yay! Lets start!
At the beginning of class, we went over the lab that was presented yesterday. The lab was called "Waves On a Snakey". We were grouped into a team of four. Each group was handed a slinky. With the slinky, we had to create waves. Then, we recorded how long it would take for the wave to reach the other end and back. The sheet will explain the rest. For those of you who missed out, I'll upload the lab.

After we corrected the lab, we watched a video. The video demonstrated effects of waves, when they are created in different circumstances. The video showed what would happen if two waves collided, the reaction that occurs when the wave pulses are displaced, and a lot of other interesting things. A worksheet was handed out after the video was completed.

Near the end of the class, a vocabulary review was handed out. I'll upload it for those of you who missed it.

Here are some final notes. A test was announced for Monday. Study hard everyone! Also, the next scribe will be...RichardG.

Transverse Waves with a Slinky
Hey, I'm Benofschool and I will be you scribe for today.
Today in class we all started on an experiment with slinkys. We used Slinkys to create transverse waves to test out a number of experiments by swinging the slinky between 2 people with another two timing and observing.. The experiments included seeing if the amplitude of the waves have a relationship with the speed of the waves, seeing if the amplitude and the speed remains the same throughout the wave. According to Ms.K this was a very frustrating experiment due to the morning class's complaints. The teacher was right. Timing the waves were really difficult do to coordination issues. Too bad we are humans, we cause human errors.
This concludes my scribe for today and homework is to finish the experiment sheet Ms.K gave us and it is due tomorrow.
The next scribe will be "Thang N."
Bye Y'all

FISRT SCRIBE, "WAVES"
Hello fellow physics classmates,
I am Sam and I will be scribing for Fridays class. We started off by looking at how waves are made and key terms. We were given booklets out that had key terms and some formulas. We learned that a continuous or periodic wave is produced by a disturbance that is moving back and fourth continuously, that is the source is oscillating or vibrating.
click HERE to see the key terms of a wave.
To find the frequency of a wave its,
frequency = oscillations/ time
The period is the inverse of the frequency,
Time = 1/frequency.
We also had a handout to do, which we already corrected in class. We were also given another handout, I guess it was for homework because we didn't really have time to do it in class. The second sheet is CHARACTERISTICS OF WAVES. make sure you finish it for class :)

Scribe List
This is The Scribe List. Every possible scribe in our class is listed here. This list will be updated every day. If you see someone's name crossed off on this list then you CANNOT choose them as the scribe for the next class.
This post can be quickly accessed from the [Links] list over there on the right hand sidebar. Check here before you choose a scribe for tomorrow's class when it is your turn to do so.
