Howdy,
We will be building and playing PVC panpipes on Thursday and Friday as part of our Sound unit. I will purchase the necessary duct tape and PVC pipe (because you will need 3 feet of pipe, but they come in 10 feet lengths). The cost per student is 75 cents for all the materials. Please bring that money to school this week. If anybody has PVC pipe cutters at home please contact me. Take care,
-Mr. Pfiester

7th-8th Grade: Week of December 15-19
Howdy,
We are continuing our Sound Unit this week. The following describes this week's homework and due dates:
Wednesday, December 17: You should remember the hearing test I gave the class a few weeks ago. I want you to go to the same website http://www.freemosquitoringtones.org/hearing_test/ and test at least four other people both younger and older than you. If you have Internet issues at home then borrow a school laptop and try people here at school (try Mrs. Fulcher!). Record the highest frequency they can hear along with their names in a table form. Did you find that younger people always have better hearing than older people?
Friday, December 19: You are going to make a rainstick for this homework. Directions can be found at: http://www.exploratorium.edu/frogs/rain_stick/index.html. I'll explain more about this homework later in the week.
Have a great week!

Howdy,
We are now in our 2nd week on our sound unit. Last week was pretty chaotic with testing and events disrupting planned activities. As such the homework that WAS due on Friday, December 5 is due on Tuesday, December 9. So the homework description and due dates are as follows:
Tuesday, December, 9: Some towns have installed sound speakers outside to purposely annoy teenagers who gather together in public areas. The sounds are usually the mosquito frequencies we discussed or classical music. Do you think this should be allowed? Why or why not? Do teenagers have the right to gather in public places in large groups? Is it legal to target specific groups as the sound speakers do? Do a brief internet search for towns that have done this. Your answer should be a 6-8 sentence paragraph.
