Welcome To Eighth Grade Science with Ms. Costa!

Hello all, and welcome to Physical Science! This year we will be introduced to the worlds of physics and chemistry and learn how they explain everyday occurrences.  By the end of the year you will understand why an ocean liner floats but a small pebble sinks. You will understand why steel rusts but aluminum does not and some of the factors that contribute to the efficiency of your four-wheeler.
Take a look to see some of the labs, lessons and activities we did last year.

Windmill Project - coming along thanks to Mr. Paul Pytel

Mr. Paul Pytel, a retired engineer and grandfather to eighth grade student Hailey Pytel, has stepped in and really turned our windmill project around!! His expertise, professional equipment and attention to detail have really helped students Hailey Pytel, Claire Beck, Moriah Teed, Mackenzie Harris, Jimmy Kline and Jay Polhamus come up with a sophisticated method to test blade design, count and pitch. Mr. Pytel says he is happy to help because it is very important to him to get students interested in science and engineering. We are so thankful for all of his hard work and input.
