Intro to Waves

On Monday we did not do very much. We talked about Science Olympiad most of the time and then watched a very cool video regarding a wave pendulum. So excited we placed fifth in the State!

On Tuesday we started our new unit on waves.  I learned that an oscillation is one full wave. Another important thing we discussed was the different parts of the wave. The top of the wave is called the crest. Another important part of the wave is the trough. The trough is the bottom part of the wave. The trough and crest are between a line which is the equilibrium. To demonstrate the wave we made a model with duct tape, wooden skewers, and gummy bears. To construct the model we taped the tape to two ring stands across the room. We then, put the gummy bears on the wooden skewers. We attached the skewers to the tape. After we constructed it we applied a disturbance(energy) and watch the wave form.

On Wednesday for our science starter we used Kahoot. For Kahoot we had to answer a series of questions about waves to help us review. I thought this was very fun and I hope we use this program in the future. To help us understand some of the wave terms we did a worksheet. In this worksheet we used a slinky to represent waves. We stretched the slinky and measured it. Then we timed the oscillations it took. After that we found the average speed.

On Thursday we used Kahoot again. I did not know some of the terms because we had not reviewed the whole chapter yet. One term I learned was the Doppler Effect. The Doppler Effect is when there is a noise but it is moving. You remain stationary so the noise begins to get louder than quieter. One example of this is a Fire Truck. The sirens are making noise and it is moving. You remain stationary so the noise begins to increase then decrease. We also finished our worksheet. After this worksheet I had a better understanding of terms such as amplitude, frequency,and wave length.

On Friday  Mrs.G was not there. Mr.Batten was our substitute and he gave us a worksheet to do. This worksheet was very challenging and required some research. Most of the topics covered on this list were more advanced versions of the material we had already learned. With some application and research we were able to complete the worksheet. Overall, I understood most of the worksheet except a few select questions.

One thing I can improve on this week is double checking my lab data tables to make sure that all of the units are filled in correctly .
