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 for Variables

Students will have to watch the video and read the online articles first to get an idea of how a wind turbine works, what kinetic energy, Betz Limit, power coefficient, wind speed, mass flow rate, energy flow rate, tip speed, and rotational speed is. Next, they will have to make some calculations to fill out…

## 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…

## Sagging Power Lines

Students will apply their knowledge of arc length, sector area, segment of a circle area formula, unit conversions, and the Pythagorean Theorem to assess whether the giraffes as the Knoxville Zoo are safe from the sagging power lines overhead. They will watch a YouTube video about the cause for sagging power lines and will then…

## Power Grid with Squishy Circuits

Students will learn about the Power Grid and how it is used to produce electricity to their house. They will learn the different components of the grid and then manipulate the grid with TCIPG. Once the students learn how the grid works, they will build a power grid with their partner with squishy circuits, batteries…
