Physics Of A Simple Wave Simulator

A sound wave is a disturbance that repeats regularly in space and time and that transmits energy from one place to another with no transfer of matter. In Activity 2 on page 8 we had to model sound waves using an instrument. In our class we used a flute as the example and when the person blew into it, sound waves were produced. As they blew and changed the volume and pitch the sound waves changed. A sound wave is created when something vibrates. When something vibrates, longitudinal waves are created which we can hear. A longitudinal wave is a wave that transfers energy through compressions and rarefactions in the material that the wave travels which are all parts of a sound wave. In Activity 2 it states in some parts of the wave, the air molecules

Wave by Sonali Deraniyagala is a life taking memoir where Sonali watched her whole family be swept away before her eyes being the only one to tell her tale. Throughout the book Sonali deals with depression and anxiety after finding out what was the cause of her family's death, A tsunami. She later explains her feelings and difficulties without her family being by her side. Relying on friends she slowly gets better by facing the one place she wanted to forget ,Sri Lanka. This was just the beginning for Sonali.

The reading of the life of Sally Ride appeared as a very engaging activity to me. While reading, Ms. House would allow simple questions and comments, but knew when to stop them and move on. Her students also seemed to know that when she moved on it was time to be quiet and listen. After reading, the students turned to a partner and discussed the story. This was a great way

In this experiment, the signal generator was set so that the frequency meter showed a reading of 1,803 Hz. The microphone was moved to a distance from the speaker so that the oscilloscope displayed a straight diagonal line. This position was of the microphone was recorded as the initial position, or beginning of a wavelength. The microphone was then moved farther in the same direction until the oscilloscope displays the same horizontal line. This position was recorded as final position, or the end of the wavelength. The distance between the two positions represents one wavelength for this frequency. This was repeated for frequencies of 2,402 Hz, 3,002, Hz, 3,602 Hz, and 4,201 Hz.

The Wave, by Todd Strasser, is a novel about a school-wide experiment about how the German people could have followed Hitler and the Nazis. Two characters Laurie Saunders and Robert Billings showed a dramatic change in their actions, popularity, and their emotions from the Wave experiment. Together they had a huge impact at their school, Gordon High.

When the wave starts out Laurie likes the concept of it and everybody else does too. But when everybody else started to grow more inclined to it she liked it less. Laurie started to come to multiple realizations about the wave after a supper conversation with her parents. When Laurie told her parent about it her father was supportive of it but her mother was not very fond of it. Her mother disliked how everyone was stripped of individuality. All the students in the wave aside from Laurie barely spoke for themselves as their own person. Just for the wave. Laurie didn't like how the experiment robbed people of their own opinions, how everyone is listening to Mr. Ross and obeying to him and how the people inside the wave treat outsiders.

Two or three mini-lesson ideas I have for beginning the year are that I have not implemented with teachers/students before are:

My students will learn about how we use water, why water is important, absorption, dissolving and float and sink in density. The second week in my water unit has a theme of the water cycle. Each day, the students learn about the different stages in the water cycle. For the preschool students, the water cycle is simplified into four stages, precipitation, condensation, collection and evaporation. In the third week, I decided to expand on the study of different bodies of water. The collection activity used in week two, where my students learned the basics about rivers, lakes and oceans, is used to learn about the biology of animal life. Students first learn about puddles and then expand their exploration into larger bodies of water. My fourth and last week of the month has a mini-theme about weather. To make things exciting I focused on storms and then ended the week learning about rainbows.

The sensory energies of light and vision and sound vibrate as waves passing through space. These waves result from reflected light or from changes in air pressure caused when vocal cords and other stuffs move. Generally eye and the ear identified the waves as light and sound. The waves of light and sound can describe in term of wavelength, frequency and amplitude. Wavelength is the distance from one peak of the wave to the next. Frequency is the number of complete waves or cycles that pass a given point amount of time. Amplitude is height of the wave from baseline to peak. These are shown in the Figure 3. The different wavelength, amplitude and frequency makes various sound and vision experience.

The red bar on the left acts as the driving piston. If it moves in a sinusoidal manner from left to right, then the wave that is produced will be a sinusoidal wave. Since the wave is sinusoidal, the wavelength, amplitude and frequency are constant. This is seen in nature as a tuning fork, which produces a periodic sound wave. In a one dimensional tube as shown above, each particle undergoes simple harmonic motion. The volume that is contained in one wavelength also undergoes this same motion. We can represent the displacement of this volume as:

All students have a different learning style and can benefit from hands on or real life activities in the classroom.

Paz describes the wave’s insatiable appetite for attention and understanding in an almost unimaginable way. He gives the wave a personality all her own as if to point out that no emotions like hers exist in the human realm. Water is in constant motion and becomes riled when attacked by wind and lightening. It reacts and becomes tempestuous and the reader can see where the wave might resemble a human woman. But she is reactionary at best and tries their relationship.

The first approach of student-centered learning that will be discussed is a teaching method called the Learning Cycle. A study was done with fifth grade students learning about sound. There were some students who were taught using the Learning Cycle, and some students were taught using the textbook approach. To see which method produced a greater understanding of sound the students were randomly selected, and an interview method was used in both groups to see what the students previously knew about sound. Then, in the instruction part of the procedure an instructor was used in both methods. In the Learning Cycle approach there were three phases: "exploration, concept introduction and concept application". During these three phases the students worked together in-groups while discussing their ideas and using manipulatives to act out the concepts. Also, the teacher would act as a facilitator, while the students discussed their ideas, and created more ideas and situations to figure out. During the lessons, the students were in active control and they could lead the lesson with their ideas and conclusions. The students were very excited to work together and the groups encouraged some of the students to share their ideas more willingly (Barman, & Barman 1996). Dinan
