Students should have already been introduced to solving equations; this lesson is meant to further their understanding and contextualize giving real-life examples of when they would need to solve equations. This is a 1 day lesson. Student will be able to substitute values for the variables in Ohm’s Law, V-IR Student will be able to […]

# Systems of Equations: Energy and Engineering Trends

Students will examine energy trends to explore why energy efficiency is an important current area of focus. They will also look at current trends in engineering domestically (demographics). They will use the systems to model different scenarios to alter trends. Students will open with a discussion of the lightbulb activity…why is it important to conserve […]

# Which Lightbulb is Better? Part 2

Students must determine ‘which is the better lightbulb?”. In the previous lesson they determined energy efficiency/cost efficiency. In this lesson, the purchase prices of the lightbulbs are introduce and students must answer the same question as well as a follow up question. “Which lightbulb should I buy?” “How long will it take before I […]

# Which Lightbulb is Better?

Students must determine “which is the better lightbulb?”. They will analyze the efficiency of different light bulbs by measuring wattage and heat emissions. Cost-efficiency will be introduced with setting up linear equations and analyzing their graphs. Students will collect data (temperature, wattage) to determine energy and cost efficiency of different lightbulbs. They will create and […]

# Introduction to Arduinos

The students will see an animated video that gives an overview a of how the U.S. electrical grid is organized and how power gets to customers. Next , they will make a human electrical circuit. Finally, students will be put into several small groups receiving printed instructions on how to create a traffic light using […]

# Kill-A-Watt Lesson

Students will become more familiar and cognizant of the amount power they are using. With use of a Kill-A-Watt device, they will calculate kWH and costs overt various periods of time. After determining energy costs of each appliance, they will find ways to save money on monthly bill by unplugging appliances or even considering investing […]

# Incandescent Bulb vs. CFL

Students will use a kill-a-watt device, 60 watt incandescent and CFL bulb in the class setting. After comparing brightness, heat, costs of bulb, they will use the information provided by the teacher to compute the costs of each bulb over 8,000 hours(approx 1 year), then costs of multiple bulbs throughout the house, etc. Incandescent bulb vs. […]

# Electric Magnets and Electric Fields

The purpose of this unit of study is to allow students the opportunity to learn more about electromagnets, electricity and magnetic fields. Students will be introduced to multiple vocabulary terminology while they work through creating electromagnets, generators, electric currents making it possible for them to explain the relationship between earth’s magnetic force and that of […]

# Energy Analysis

Students will translate historical data from a table into a graph to establish trends in energy consumption and production, and factors that contributed to the trends in consumption and production. Lesson 6-analyzing historical data

# Magnetism and Electricity

Investigate the relationship between magnetism and electricity and recognize that electricity can be produced using a magnet and wire coil. lesson plan 3- Hardison
