Demonstrate the safe and proper use of electronic lab equipment.
DefinitionDemonstration should include
- acceptable training and performance with all tools, machines, equipment, and supplies (including care and maintenance of all items)
- monitored/supervised performance during each activity
- ability to locate posted safety rules, precautions, and first aid and emergency instructions
- willingness to wear personal protective equipment (PPE), when necessary, and to adhere to injury-reporting protocols
- definition of alternating current (AC as that which flows first in one direction and then in the opposite direction).
- Why is safety important in the lab and in the workplace?
- What safety precautions should be taken when using hand tools, machines, equipment, and chemicals in a lab?
- What safety precautions and responsibilities should be considered for various electronics?
- What safety precautions are used when operating an AC generator?

History and Social Science
The student will apply social science skills to understand economic systems by
- identifying the basic economic questions encountered by all economic systems;
- comparing the characteristics of traditional, free market, command, and mixed economies, as described by Adam Smith and Karl Marx; and
- evaluating the impact of the government’s role in the economy on individual economic freedoms.
The student will investigate and understand that experiments in which variables are measured, analyzed, and evaluated produce observations and verifiable data. Key concepts include
- designated laboratory techniques;
- safe use of chemicals and equipment;
- proper response to emergency situations;
- manipulation of multiple variables, using repeated trials;
- accurate recording, organization, and analysis of data through repeated trials;
- mathematical and procedural error analysis;
- mathematical manipulations including SI units, scientific notation, linear equations, graphing, ratio and proportion, significant digits, and dimensional analysis;
- use of appropriate technology including computers, graphing calculators, and probeware for gathering data, communicating results, and using simulations to model concepts;
- construction and defense of a scientific viewpoint; and
- the use of current applications to reinforce chemistry concepts.
The student will plan and conduct investigations using experimental design and product design processes. Key concepts include
- the components of a system are defined;
- instruments are selected and used to extend observations and measurements;
- information is recorded and presented in an organized format;
- the limitations of the experimental apparatus and design are recognized;
- the limitations of measured quantities are recognized through the appropriate use of significant figures or error ranges;
- models and simulations are used to visualize and explain phenomena, to make predictions from hypotheses, and to interpret data; and
- appropriate technology including computers, graphing calculators, and probeware is used for gathering and analyzing data and communicating results.
