How Do Rockets Fly? (Reading Comprehension)

Science teachers can be reading teachers, and reading teachers can teach science! "How Do Rockets Fly?" compares rockets and their engines to an inflated ballon that shoots through the air when you let it go. What both have in common is that escaping gases obey Newton's Third Law. Newton's Third Law states that for every action there is an equal and opposite reaction. The action force of the escaping gas is countered by the reaction force of rocket (or balloon) motion.
