General Lesson Information
 Lesson Plan ID: 34372 Title: Rocket Activity: Heavy Lifting Overview/Annotation: Raising heavy payloads to orbit is challenging.  Rockets require powerful engines and massive amounts of propellants. NASA is looking for creative ideas for launching heavy lift vehicles to deliver supplies to Mars.  Student teams receive identical parts to build rockets. The team that is able to lift the greatest payload into space (the ceiling) is the winner.This lesson was created as part of the 2016 NASA STEM Standards of Practice Project, a collaboration between the Alabama State Department of Education and NASA Marshall Space Flight Center.
Associated Standards and Objectives
Content Standard(s):
 Science SC2015 (2015) Grade: 9-12 Physics 1 ) Investigate and analyze, based on evidence obtained through observation or experimental design, the motion of an object using both graphical and mathematical models (e.g., creating or interpreting graphs of position, velocity, and acceleration versus time graphs for one- and two-dimensional motion; solving problems using kinematic equations for the case of constant acceleration) that may include descriptors such as position, distance traveled, displacement, speed, velocity, and acceleration. Science SC2015 (2015) Grade: 9-12 Physics 2 ) Identify external forces in a system and apply Newton's laws graphically by using models such as free-body diagrams to explain how the motion of an object is affected, ranging from simple to complex, and including circular motion. a. Use mathematical computations to derive simple equations of motion for various systems using Newton's second law. b. Use mathematical computations to explain the nature of forces (e.g., tension, friction, normal) related to Newton's second and third laws.

Primary Learning Objective(s):

Learning Targets:

I can design and construct a balloon powered rocket to launch the greatest payload possible to the classroom ceiling.

When analyzing the forces acting on an object:

• I can draw and label a force diagram for the object
• I can recognize that balanced forces always result in constant velocity (including v = 0) and unbalanced forces always cause an acceleration in the same direction as the Fnet.

I can apply F=mg to calculate the gravitational force on an object with mass m in a gravitational field of strength g in the context of the effects of a net force on objects and systems.

I can predict the motion of an object subject to forces exerted by several objects using an application of Newton’s second law in a variety of physical situations with acceleration in one dimension.

I can construct explanations of physical situations involving the interaction of bodies using Newton’s third law and the representation of action-reaction pairs of forces.

Video Analysis Extension Activity:
I can re-express a free-body diagram representation into a mathematical representation and solve the mathematical representation for the acceleration of the object.
