Changes in Motion: Push and Pull
Supporting
TEKS Objective
The student is expected to demonstrate and observe how position and motion can be changed by pushing and pulling objects to show work being done such as swings, balls, pulleys, and wagons.
Essential Understanding
The student knows that forces cause change and that energy exists in many forms.
Science Background
Rockets, Force and Motion: K8 Science (video) – A force is a push or a pull that can change an object’s motion. Dr. Greg Vogt uses rockets to explain force and motion.

Signature Lesson
Pop Can Hero Engine: NASA Rockets Educator Guide (PDF / Video) - Students make a Hero engine from a pop can and then demonstrate and observe how the forces of action and reaction produced by falling water cause the “engine” to rotate. The lesson mentions Newton’s Third Law as the objective, but it addresses TEKS 3.6B. Lead a class discussion about the forces that make the can rotate, and ask students if “push” or “pull” forces are making the can move. Students make a Hero engine from a pop can and then cause the “engine” to rotate with the forces of action and reaction produced by falling water.
