A thrown basketball, a kicked football, an elastically launched catapult payload, and a free-falling solid fuel or pressurized gas-propelled rocket all have one thing in common. They are all projectiles familiar to elementary students. A projectile is an object thrown with an initial velocity and then allowed to move without thrust along its trajectory under the force of gravity alone. Whether launched by air from a balloon, water, or a different means common to these types of projects, projectiles are found both in physical science and STEM-related programs, often to teach about projectile motion. This article provides standard operating procedures that elementary teachers need to be aware of and incorporate into their lesson planning to provide a safer teaching and learning experience in working with projectiles.
