This fun puzzle is a terrific review at the completion of Science students. They must cut the squares out and reorder them in a 4 by 4 square based upon the ideas and concepts around the edges of the squares. It is a great activity to work in teams. When the students have the squares in the correct place it makes a statement. There is repetition of letters so that students must match the ideas around the 4 edges of the squares. Fun and challenging.
