Tech Lesson 11-5a:  Electricity and Circuits:

Standards:
Demonstrates understanding of basic technology and telecommunication tools
Operates Basic technology tools and applications
CSTA Level I Standard 4: (3rd to 5th) Use general purpose productivity tools and peripherals to support personal productivity, remediate skill deficits, and facilitate learning throughout the curriculum.
CSTA Level I Standard 5: (3rd to 5th) Use technology tools for individual and collaborative writing, communication, and publishing activities to create presentations, and publishing activities to create presentations for audiences inside and outside the classroom.
CSTA Level I Standard 9: (3rd to 5th) Determine which technology is useful and select the appropriate tools and technology resources to address a variety of tasks and problems.

Basic Skills:

S5P3: Students will investigate the electricity, magnetism, and their relationship.
b. Determine the necessary components for completing an electric circuit.
M5P1: Students will solve problems (using appropriate technology).

Key Vocabulary:
current
electrons
switch
resistor
battery
conductor
series
parallel
insulator

Objectives:
Students will identify flow of current in simple Electrical Circuits.
Students will identify and create drawings of Series and Parallel Circuits with the elements of Battery, resistors, Conductors, and Switches.

Project Requirements Basic:
1. Create a Diagram with Presentation software that shows a simple Circuit with the following elements:
a. Battery
b. Conductor Path
c. resistor (Light Bulb)
d. Switch.
2. Create two diagrams comparing Series and Parallel Circuits.
3. Use schematic icons to create circuit drawings with Battery, Conductor, Switch, and resistor.

Process:
1. Discuss how a light switch works.  Compare Electricity to flowing water.
2. Students go to following websites and define vocabulary words:

3.  Start Open Office Impress and create a drawing of a simple light bulb, battery, wire, and switch.  Use drawing to convey flow of electricity.
4. Create drawing of Series and Parallel Circuits
5. Create Electrical Diagram of simple circuit with one resistor, switch, power source, and conductor.
6. Save presentation as "Lastname Circuits" in file area.

Examples:


Optional Advanced Assignment:
Use Scratch to create a dynamic picture of an electrical circuit.  
1. Use Sprites to represent Battery, Conductor, Switch, and Resistor.
2. Use movement to show flow of electrons around the circuit.
3. Use costume changes in Resistor and Switch sprite to show functions of circuit.
