**Enduring Understandings**

Insights earned from exploring generalizations via the essential questions (Students will understand THAT…)

**Essential Questions**

Inquiry used to explore generalizations

*The interrelation of motion, force, and energy can be described,*

*measured and explained.*

*“For every action, there is an equal and opposite reaction”*

*Force equals mass x acceleration*

*The center of pressure, center of gravity, drag, stability and thrust must all be considered to have a successful liftoff and rocket flight.*

*How can water and air make a rocket fly?*

*How can a force affect the motion of an object?*

*What makes a rocket fly?*

*How do the laws of motion affect our daily lives on earth?*

*What variables can you manipulate to affect the movement of objects?*

*How do the forces of*

*lift, drag, friction, thrust, and gravity act on a rocket.*

*How does Newton’s first law apply to rockets? (balanced forces and unbalanced,)*

*How does Newton’s second law apply to rockets? (F=ma)*

*How does Newton’s third law apply to rockets? (equal and opposite, action and reaction)*

*What determines how far a water bottle rocket travels?*

**Knowledge and Skills**

What students are expected to know and be able to do
