ESCI 300, Science 9; Physical Science: Characteristics of Electricity lesson Plan:
Key concepts from outcomes: CE9.2:
Calculate values of unknown quantities in electric circuits using Ohm’s Law (I = V/R).
Activities/Demos:
Design dc circuit’s that will illustrate the characteristics of “Ohms-law” in a series and
parallel circuit. This could be accomplished in numerous of ways. One example could
include visual indicators such as energizing an LED in series with each resistor being
used in the series and parallel circuit and secondly use voltage and current meters to
display their measurements.
How should we teach ohms law?

What is a resistor? (youtube video):
Note: in the following “Resistor-YouTube” video, regarding the example of the Red LED,
the shorter terminal of the LED is connected to the positive terminal of the 9 Volt battery.
This implies the circuit designer clipped the positive terminal shorter than the negative
terminal of the LED. Typically the longer terminal of an LED is positive and is called the
Anode connection.

Assessment:
Assessment of the student’s progress would be obtained in real-time by observing and
monitoring them during the lab period and also during the teaching of the theory section
of the lesson, via the inductive inquiry and concept attainment teaching strategy.
Processes, NOS, Inquiry:
The learning processes would include both a theory and practical component. The NOS is
integrated in with the experiential learning section of the experiment. The teaching
strategies, made up of the inquiry and concept attainment methods would be utilized.
