Lesson Plan

This document provides an instructional plan for a unit on small engines. The instructor is Garren Wetzel and the course is Power Units. The unit will last 30 minutes. Students will learn to identify basic engine parts, describe how the parts work together, and summarize what is needed for an engine to operate. Materials include a projector, dry erase board, engine parts, and a complete small engine. The instructor will motivate students by explaining how engine repair skills can help in careers or side jobs. Students will then identify engine parts, see a diagram of how parts work together, and summarize the four-stroke cycle and that engines need fuel, fire, and air to operate. Objectives will be evaluated through exams based on the

Instructional Plan Instructor: Garren Wetzel

Course: Power Units


Unit: 1
TEKS:
Lesson Title: Small Engines
Estimated Time: 30 minutes
Objectives
After completing this unit of instruction students will be able to
A. Identify basic parts of an internal combustion engine;
B. Label and describe how the parts work as one; and
C. Summarize how and what it takes for an engine to work.

Materials, Supplies, Equipment, References, and Other Resources:


Materials, supplies and equipment:
Projector
Dry erase board with different color markers
Small engine parts
Complete small engine

Interest Approach (Motivation):


Explain why learning about small engines can help in real life
- Example: Can make good money fixing small engines as a side job
- Example: You are more valuable to an employer if you can fix the equipment that you use
for the job
- Has anyone repaired or worked with small engines before?

Materials Key Questions
A1: Begin identifying basic parts A. Identify parts of an internal combustion engine:
of an internal combustion 1. Four cycle engine- Takes four strokes to complete a cycle
engine 2. Piston- connected to crankshaft with connecting rod
3. Crankshaft- turns up and down motion of piston into rotational
motion
4. Cylinder- is what the piston operates inside of
5. Block- mass of metal that contains the cylinder
6. Flywheel- keeps engine parts moving
7. Spark ignition- spark plug and wire
8. Carburetor- mixes fuel and air

Materials Key Questions
B. Label and describe how parts work as one;

B1. Use diagram to show how


parts work together.

C1. Summarize briefly how and C. Summarize how and what an engine needs to run:
what an engine needs to run. - A four stroke internal combustion engine. The four strokes
are intake, compression, power, exhaust. The piton is
driven downward on the power stroke due to rapid
expansion of the gas and air mix that the carburetor mixes
and then enters the combustion chamber through the
intake valve. After this the exhaust valve will open and the
piston will come back up and force the exhaust gas out.
Next the intake valve will open as the piston goes back
downward creating a suction that draws in the fuel. The
piston will go up into the compression stroke where the
spark plug will send a spark igniting the fuel.
- An engine needs 3 essential things. Fuel, Fire and Air.

Evaluation:

Objectives will be reviewed before examinations. Exams will be developed based on objectives as
taught in class.
