Good morning. �I am putting together a project for my future (fall 2014) high school geometry students on perimeter, area, and volume. �Part of the project involves students computing the volume of a pair of spare cylinder barrels to determine the volume of 598 cc.
So, if I had a pair of pistons, ones that cannot be used for a running engine, that would be great!
Thank you.

Re: Need damaged pistons n600
Hi Bob,
Are you going to have your students look at the problem with the whole system (cylinder barrel, piston,rings,head gasket, and cylinder head)? The pistons have a slight dome and some relief for the intake valve. Measuring the volume of the cylinder head is going to be a tough one for a high school student if they are using paper and pencil and math. The easy way to do it is to measure how much liquid fills the volume.
And using math to figure out the volume of the piston's dome and relief is going to be challenging. The easy way is to measure the change in volume when inserted into a liquid.
At least you can show your students that geometry isn't just about math, it is about shapes. They can use liquid, Play Doh, sand, balloons, etc. to arrive at a result. I think I like the balloon approach. Squeeze it into a complex shape (e.g. the cylinder head), fill with air till it expands, when you remove it, it is a sphere due to atmospheric pressure. A sphere is easy to measure the volume.
good luck on your project,
Dale
