I created these for our unit study on the weather. Student s will be able to hold the viewers up to the sky and identify cloud types. Print this out and cut out the blank middle section to create a window. You can print on card stock or regular copy paper, but when using regular copy paper, I highly recommend you laminate. Once laminated, cut the center out and trim the edges. Use a large craft stick as a handle and tape to adhere the stick to the viewer.
