STEM 434-5E Lesson Plan Final Draft
Possible Preconceptions/Misconceptions:
Students may have some misconceptions about where electricity comes from and how it is controlled
through circuits. They may understand a little about conductors as we discuss rules about being out in
lightning storms or rules around the home like playing with electrical sockets.

Lesson:
The teacher will supply students with the materials listed above.
The teacher will help the students strip the insulation off the tips of the wire (about ¼ inch) to
expose the wiring.
The students will build a simple circuit like the one shown below.
The students will be given a data sheet (found here) for observations during the experiments.
The students will try different ways to close the circuit (connecting the circuit in different ways
like both wires touching one pole of the battery, connecting the wore in the same place on the
light fixture, etc.). They will know the circuit is closed when the light bulb lights up.
The teacher will spend time with each group to assess understanding of how the circuits are built
and the difference between an open and closed circuit.
Once a firm understanding of a closed circuit has been established, the students will replace the
switch with one of the additional objects listed above.
The students will make predictions about which objects will close the circuit.
The students will observe and record which objects closed the circuit (conductors) and which
objects left the circuit open (insulators). The students will be given time to experiment with other
objects of their choice found in the classroom.
The students will record data on their worksheets (found here) and come back to the whole
group to discuss results.
Probing/Clarifying Questions (Group discussion):
What connections can you make between the materials that closed the circuit and those that did
not?
What does that tell us about the objects that closed the circuit? What materials are they made
of?
Can you think of an historical event that may be another example of the experiment we just did?
Can we think of any examples of a circuit within this classroom? At home? In our environment?
What are some instances when an insulator would be necessary? Name some examples.
EXPLAIN: Concepts Explained and Vocabulary Defined:
Day 2 (10 minutes)
Insulators and conductors: Energy cannot flow through insulators. Some insulators are used to protect
people and animals from electrical shock. Conductors allow energy to pass through them. Conductors
are sometimes things we would not expect like water.
Open and closed circuits: A circuit must be completely closed in order for electricity to flow correctly. An
open circuit interrupts the flow of energy. Turning on and off a light switch is essentially opening and
closing a circuit.
Vocabulary:
Electricity- a form of energy resulting from the existence of charged particles
Conductor-a material or device that with transfer heat or electricity
Insulator-a substance that does not allow electricity to pass
Circuit-a complete and closed path around which a circulating electric current can flow
Current- a flow of electricity that results from the ordered directional movement of electrically charged
particles.

Summative Assessment:
Day 5 (45 minutes)
Formation of partner presentation of processes and results:
5 slides (Google or PowerPoint) with the following requirements:
Slide 1: Explanation of conductors and insulators
Slide 2: Explanation of closed and open circuits
Slide 3: How they tested the materials to see if they were conductors or insulators
Slide 4: Results-Which materials closed the circuit (conductors)? Which materials did not close
the circuit (insulators)?
Slide 5: Conclusion
Each partner must participate in preparing the slides.
