The FOSS Electronics Course emphasizes the use of knowledge and evidence to construct explanations for electrical energy and its use in technology. Students learn fundamental electrical circuitry and basic electronic principles. They make simple and complex circuits, quantify electrical interactions and properties (current, voltage, resistance) using a digital multimeter, and discover how different components affect circuits (resistors, diodes, LEDs, capacitors, transistors). They make and read schematics and construct solid-state devices.
FOSS EXPECTS STUDENTS TO
- Discover how to create complete circuits and how to identify series, parallel, and short circuits.
- Discover how resistors influence the performance of lamps in electrical circuits and develop a model that explains what resistance is and how it might affect the flow of current in a circuit.
- Explore, measure and manipulate one of the two main attributes of electricity, voltage, and discover how voltage can be influenced by components in a circuit.
- Explore consumer products to discover the kinds and numbers of electronic components used in their design and consider the impact of technology on American life.
- Discover the rules for predicting the total resistance imposed by multiple resistors places in series and/or parallel.
- Discover the characteristics of capacitors, compare them to components with which they are familiar, and use them in circuits to perform new functions.
- Understand the concept of electric current and use their understanding to solve circuit problems.
- Discover the characteristics of transistors, compare them to components with which they are familiar, and use them in circuits to perform new functions.
- Become familiar with and acquire vocabulary concerning these concepts: circuit, Ohm’s law, component, meter, digital, energy potential, current, resistance.
- Exercise language, social studies, and math skills in the context of science.
- Use scientific thinking processes to conduct investigations and build explanations: observing, communicating, comparing, organizing, relating, and inferring.
