Electronics 11/12 (Oral Lesson Plan)
Lesson – Teaching the Resistor Colour Code
Purpose: to allow students to know the value of the various resistors. Resistors are devices that have
resistance when electrical current attempts to pass through it. Anything that is an electrical component
contains resistors and students need to know how much current each type of resistor is capable of
resisting.
There is a universal way of determining how much resistant a resistor has and it is called the “Resistor
Colour Code.”
PLO’s: It is expected that students will:




Demonstrate skill in the use of application of printed circuit board production equipment
Calculate and measure voltage, current and resistance in DC circuits
Demonstrate the use of the resistor colour code
Explain the function and theory of common electronic devices include resistors
TSWBAT:
Correctly identify the ten colours common to all resistors and understand the formulaic value of each.
Students will learn, create and develop their own mnemonic to help internalize these colours and
values.
Introduction: Hook
Projector – PP slides
How are colours distinguished in society? Red means stop. Green means go. Students brainstorm.
What do colours symbolize? What does orange mean for you? Do certain cultures attribute different
meaning to colours, etc.
Does anyone know what a mnemonic is? Examples: “Never Eat Shredded wheat” NESW
Because “Big Elephants can always understand small elephant.”
Examples?
Mnemonic – Bright boys rave over young girls but veto getting wed.

Activation of prior knowledge
Students are already aware of what resistors are. Students understand the basic function – they resist
the flow of current in an electrical circuit.
Motivation: This lesson is the next step in their understanding of how resistors work and they are
getting closer to being able to build their own circuitry. Students will then get to use circuit boards and
bread boards to start building their own simple electronics projects (ie the “winky blink” and “Sammy
the snake.”)
Students have looked at them touched them, today they were told they would be introduced to the
colours.
The four colors on a resistor allow students to calculate the value of said resistor. Before we can do that,
we first need to figure out a way to remember what the value for each color is. A great way to do this is
by using a clever mnemonic , there are several that have been devised for the resistor color code but
this one is the most appropriate for students.

At this point I will ask students to work at their table in groups of 4-5 and come up with their own group
mnemonic. Language must be appropriate and there must be a theme to their mnemonic. Students will
then present their mnemonic to the class and the class will vote on the best mnemonic.
Students will be given a rubric to vote on. Four categories out of 5 marks each. The winning group will
have their mnemonic made into a poster (by Mr. Snead) and it will laminated and posted in the
classroom. This will them become the class mnemonic for the colour code resistors.
Carpentry and Joinery 11/12 (Written Lesson Plan) Lesson: Student Proposal for final project
Purpose: This final projection is to showcase the culmination of the skills learned in the senior wood
class and to allow the students to have input into the design of their own final project. This project is
designed to allow students to tap into their own creativity and to showcase the skills they’ve learned in
a learning style that is best suited to their individual personalities.
PLO’s: It is expected students will:



identify, describe, and select engineered wood products and composite materials for a given
project
construct and finish a project that uses a variety of adhesives, fasteners, hardware, and finishes
demonstrate proficiency in using a variety of measuring instruments, layout tools, and
mathematical techniques to solve technical problems.
TSWBAT: To choose a project that is within their acquired skill set – in a clear, cohesive and realistic
manner. Students will need include a demonstration of understanding that meet the principle learning
outcomes of the course. See PLO’ s above.
Introduction:
Hook: Show a power point slide show of previous projects students have designed and built for their
final projects in Carpentry and Joinery 11/12.
Introduce the proposal – your proposal need not be a set of specific plans, initially. This proposal
process can be proposed in a number of ways. For example, a set of orthographic drawings, a few
paragraphs explaining what you want to do or you can get creative.
Holmes on Homes, Bob Villa, a how to video on youtube,
Criteria:
Materials, cost analysis, time frame,
Design is a process: (design process steps)
Steps 1 – 6
Proposal must be worthy of a senior and not a junior project. Mr Snead will be approving each project.
We will have class time to work on your proposal.
