I could not wait to make these for my classroom as we were setting up and reorganizing my classroom Science Center I wanted a new copy of these to be posted at eye level for the children to see. I am able to use these as a reference when we are working through investigations. I also have these posted on another wall in my room where I post under each poster a step of an investigation we are working on. Doing that has helped me to discuss each step with my class and move through the processes. This download includes DIZZY DOTS on BLACK and PLAIN WHITE posters. As a bonus I Can Be A Scientist posters are included! 2012 and the 2013 Versions are BOTH included so this does have a duplicate set!
