Subject:
Electrical circuit systems
Students explore the transfer
of electrical energy in circuits and the design of circuits to
control a variety of devices. In the first lesson, students
explore the
principles and devices that they study
of energy and circuits.
The unit contains 25 lessons in the following three parts:
|
 |
Electrical Energy - Students begin by investigating
static and current electricity and the transfer of energy. They
build electric circuits, use ammeters and voltmeters to measure
current and voltage, and calculate the power in devices in series
and parallel circuits. They draw schematic diagrams of circuits
and develop a model for electricity, using a water flow analogy. |
|
|
Electrical Components - Students apply what they have
learned about current, voltage, and power to calculate the total
amount of energy an electrical device uses when it operates for a
period of time. Students examine a series of devices (containing
resistors, capacitors, diodes, wires, and solar cells) and
identify the function of each component in the circuit.
|
|
|
Electrical Systems - Students identify general
properties of systems by focusing on familiar systems and on the
use of feedback in control systems. They construct a thermostat
using a bimetallic strip to control a fan and thus the temperature
of the strip. They are challenged to use what they have learned
about circuit components to build an electric circuit to perform a
specific function and to make a class presentation of their
system. |
The Anchor Activity (a research
project) requires students to do an energy inventory of their homes
and calculate the cost of using various electrical devices. The
culminating assessment for the unit requires students to identify an
electrical component in a circuit in a sealed box. Unit length: 8-12
weeks of instruction.
