The Best Blog Ever!!

Ok so today we read the first couple pages in the yellow booklet. We learned that sound is a LONGITUDINAL wave. (Remember that!) Also, slightly different sounds produce a term a called "beats" when combined. Beat waves are the difference in the sounds. For example, if one sound is 440 hertz and another sound is 436hertz then the beat wave (difference) is 4 hertz. Yeah....that's all I can remember because it's like really late. Anyways we also got a worksheet that had questions like, if a man sets his clock to a factory's whistle that rings at noon and he is 3 km away, will his watch be BEHIND OR AHEAD? We also got homework in the yellow booklet. Questions 3,4,5,7,8,9 or something like that. Then we had a fire drill. Oh yeah and the most exciting part of the day was ms.K's pendulum (I think i spelled this wrong) experiment that totally worked! HAHA......ok enough sarcasm. Well I don't know anyone's name in the class, oh wait i pick Cow Milk to scribe for tomorrow...ok goodnight...i hope i make it to school tomorrow
