Wind Turbines and Proportions

After briefly learning about wind turbines and how they generate power for the grid, students will create their own windmills in class. Students will then apply ratio reasoning to figure out how many homes (on average) a windmill can power. How do wind turbines get power into our homes? How many homes can a wind turbine […]

Solving Equations Using Ohm’s Law

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 […]

Applications of Cosine Curves

Students will have to read the assigned articles and video first to get an idea of what a power factor, watt, and the power grid is.  Next, they will conduct an experiment of three different light bulbs to determine what their power factor is, the temperature, and the amount of watts being used.  The students […]

Applications for Sine Curve

Students will understand that there has to be exactly enough power on the grid for what is being used by consumers after watching the assigned videos and reading the assigned articles.  Students will use their knowledge of how to recognize and construct sine functions to determine how frequency, amplitude, and DC offset will change what […]

Exploring Engineering

In this lesson, students will explore various career fields (specifically various types of engineering).  They will answer questions to help them find their passion and use that to consider what career field they may want to pursue.  Students will draw a connection between what the content in Geometry and the job descriptions of several different […]

Reviewing Regression Models

Students will create regression models to demonstrate the trends in coal production in Kentucky, Eastern Kentucky, and Tennessee based on provided data.  They will use this model to predict when coal production will cease in these areas.  The class will discuss as a whole why this model may not accurately represent the data for an […]

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 […]
