This is a great lesson to teach reflections. I found the idea for this lesson on the blog, Fine Lines. Basically, all you have to do is have students draw and color the top half of their paper with regular washable markers. Then students spray water on the bottom half of their paper. After this, students fold their paper and rub. This makes a simple easy print of the image.
I allowed my students to draw any landscape image. Some students drew houses, while other drew castles, mountains, or farms.
This is a great example of art that connects to math. This one is easy enough to be done by either the art teacher or the classroom teacher.
