Sinusoidal Graphs Using Daylight Time Around the World

Lesson Plan

I will take photos to supplement my project and provide context for my students to understand where the cities are not only in the world, but relative to each other. I will also collect any maps I may encounter during my journey.

Pre-Departure Preparation

In my PreCalculus class, we complete a unit on Sinusoidal graphs. As an extension to my "Modeling with Sinusoids" project, I will have my students compare the minutes of daylight in multiple cities from this trip using three different forms of modeling (data tables, by hand using the max and min, and nonlinear regression.) I will have my students find datasets that show the amount of daylight for each city during the year 2019. By extending this project to cities that might be unknown to many of my students and by using cities that are relatively close to each other, they will gain knowledge of geography and build better connections between the coordinates of a city and its subsequent implications of the minutes of daylight vs. darkness throughout the calendar year.

Preparation During Travel

I will research the different cities we will be visiting, print out a detailed map, and get the minutes of daylight charts from the US Naval Observatory for each city.
