### Lesson Plan and Procedures

Note: Energy is a thread of learning for students

1. Review energy basics.
2.
Review the SPARK! Education energy video as well as the Darlington race footage. Identify the types of energy in the following locations associated with racing:
3. Review the SPARK! Education lessons for middle and high school listed above.
4.
Select one of the lessons and conduct an experiment. You will be using the experiment to figure out the energy and work of the devices you create. You will need a scale for measurement and a tape measure.
5.
Build the car(s) related to the lesson. Conduct the experiment as outlined in the lesson to ensure you have a functioning vehicle.
6. Using your vehicle, calculate one the following formulas to understand how work and energy can be measured by your vehicle.

a. Define potential energy.

Formula abbreviations: m = mass (measure in kg); v = velocity; g = gravity; h = height; a = acceleration; w = work; d = displacement

Newton’s second law:
f = m*a

Work formula:
w = f*d

Potential energy formula:
P.E. = m*g*h

Kinetic energy formula:
K.E. = ½mv2

7. Whew! STEM for energy is important. Without the math, science, engineering and technology facets coming together, the experiment wouldn’t have been successful. Crew chiefs and engineers need to understand how energy and work will impact the race car.
