Sound, Sound Energy and Speed. The lesson first reviews sound including how it is heard and how it is created. It then requires the students to perform an inquiry activity into the how noise cancelling headphones work. Lastly the speed of sound is examined including how its speed changes in different temperatures. To reinforce this, the lesson includes multiple practice questions. There are 2 videos embedded right into the lesson. Simply view the lesson in slideshow mode and click the video image. The video will automatically open in your browser. The videos are embedded on my site so that I can keep them updated and replace them if needed.
The PowerPoint contains diagrams, examples and explanations. It includes the lesson (student and teacher versions of the PowerPoint) and 2 videos. I have used this lesson in my own classroom with great success.
Included in the lesson package is:
– The teacher version of the PowerPoint
– The student version of the PowerPoint
– 2 embedded videos
– Student lesson handout
In order, the lesson covers:
– Creating Sound
– Moving Sound
– Noise Cancelling Headphones
– The Speed of Sound
The student version of the PowerPoint contains multiple blanks that need to be filled in throughout the lesson. These blanks are conveniently underlined and bolded on the teacher copy. I have found this to be the most effective means of keeping my students engaged and active without having them write everything out. This also leaves more time for discussion and activities.
