Hey people, as you all know we had a test yesterday and i hope everyone did very well.

Today in class we did three labs with sound waves. The first one was using a ruler. In this lab you had to hold a ruler on the side of the desk and push it down and let it go so it makes a sound, producing sond waves. The second lab we did used a beaker of water and a plastic cylinder. In this lab you had to blow into the cylinder without water in it and listen to the sound, then you had to pour some water in and listen for a change in sound, finally you had to blow across the top of the tube while pouring water into the tube and explaine what you heard. Ther third lab was the most fun, in my opinion anyways. In this lab we got to use the tuning forks. We got to see how different size tuning forks with different frequencies made different sounds. The last thing we did in class, before we had the first of two fire drills in one day, was a vocabulary work sheet.

Well thats what we did in class today. Hope everyone has an amazing weekend.
