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. Read more
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 Read more
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 Read more
Different types of light bulbs have different power supplies and life spans. Below are links to construct your own LED, complete various LED projects, and learn more about the circuitry behind the bulbs we frequently use. Homemade LED white light Read more
