This project is based on a material called Contrast-o. I found it in a box years ago and because of numbers, I was able to give one piece to each of my students to make into a project. it costs about 15 dollars for a 10 pack, so this will be a one off project. Its too expensive to purchase every year. The results were striking though! I followed a lesson I found on http://www.thesmartteacher.com. It was a great resource including a rubric, powerpoint and lesson details. We also looked at a previous post I made on Pen Knife Safety. Find that here.
Here are some of the wonderful examples.
