This is a comprehensive Science FCAT pacet that could be used in class or as a homework review and reinforcement. I use it along with the FCAT review that I also have for purchase. They do the FCAT review in class, I check it, and then they use that review to help them on the FCAT homework. Heredity, Forces, Adaptaion & Evolution, Cells, Geology, and more are covered. Everything is standards based and targets the areas covered on the Science FCAT 2.0. E-mail me with questions.
