Week 30 reflection

I missed three class periods this week because of AP tests and such.  So I can only talk about a few things for week 30.  What we did do this week is learn about sound waves.  We also went outside and did an experiment with the cement decorations outside to show how the waves bounce off and amplify.

We learned that the speed of sound is about 356 meters per second ( I think I may be wrong but that's what I thought it was).  We saw that distance affected when you saw the sound and when you heard it.  We watched a video where Steve Elliot was clapping wood blocks together and was walking backwards.  The farther he got down the field, the later the sound came after we saw him clap the blocks together.

The experiment that we did this week was we went outside to the cement decorations outside of the school and talked to them.  What happened was it amplified our voices and made sound like we were talking into a microphone.  We were told that when you talk into a space that can bounce the sound waves together, what you get is an amplifying affect that makes the sound louder.

I thought that this week I got what was being taught to me.  Even though I missed a majority of class this week, I feel like I still learned something.  I thought that the microphone experiment was cool because I didn't think that it would work.
