My Science Experiment: Flip Book

I made a flip book. I took cards that were different colors. Then I took a piece of paper and put lines on it. Then I drew pictures. After that I cut them out and put them on the cards.  I’m going to explain how you use it. You have to flip it and it looks like the two players  in the drawings are really moving. One player is dropping back to throw a pass, while trying to avoid being tackled by another player. The quarterback was able to get the pass off before being tackled. The pass was caught for a touchdown.
