Part 2Have the students color their F-15 ACTIVEsand punch a small hole in each F-15 ACTIVEat the marked center of gravity with a needleand thread. Tie a large knot at the bottom.Hang from the ceiling using paperclips orhooks. Hang the F-15 ACTIVEs low enoughso that students can use them to completelesson 3.Assessment1. Conduct a class discussion where studentsdemonstrate their understanding of:• Balance• Stability• Center of Gravity2. Ask students to predict what they thinkmight happen if the teacher pushes theF-15 ACTIVE in:• A forward direction• A sideways direction3. Push the F-15 ACTIVE and allow it toswing back to a resting position. Discussthe action in terms of balance andstability. Compare the push to a pilotflying (controlling) the airplane and theairplane being designed to return to astable position. The F-15 ACTIVE usescomputers to integrate the control surfacesand the vectored thrust so that the plane isstable.ExtensionsUse other shapes to find center of gravity.
