LED Lighting Cost per Kilolumen

Leave a comment

This is a TI-84 activity that uses Mathematical Modeling and Climate Change data. Here is where you can get the data for a TI-84 or TI-84 CE: LEDCOST program. You can get the student sheet here: LED Lighting Cost Student and the teacher notes and solutions here: LED Lighting Cost Teacher. Or you can get all 3 files in a zip folder here: LED Lighting Cost All Files.

I will be giving a week-long course at Exeter Academy this summer that will illustrate many activities like this one. If you are interested, check out session 32 at this link: https://exeter.edu/sites/default/files/media/MathCourses2019%20Updated.pdf

Payday Loan Companies

Leave a comment

Payday loans are a small, scorned part of the financial industry. But in the states where such lenders are legal, they are pervasive — there are almost as many payday lenders as McDonald’s and Starbucks in the United States. About 12 million Americans take out such loans each year, spending more than $7 billion on fees, according to Pew Charitable Trusts.

Hot Car Temps Modeling Scottsdale, AZ

Leave a comment

As of January, 2019, 794 children have died due to vehicular heatstroke since 1998. All of these deaths could have been prevented.

In this math activity, we model the data with appropriate mathematics and create social awareness of these tragedies. This is written for the TI-84 CE but can be done on other platforms. Below are links to the student sheets, teacher notes, and TI-84 CE program with the data. Following that is the student PDF, and then the teacher PDF. There is also a website that brings attention to this data and much more: http://noheatstroke.org/

A big thank you to Jan Null at San Jose University for collecting, organizing and providing this important data at this website.
This activity uses data from a school parking lot in Scottsdale, Arizona.                            There is a similar activity that uses data from the TI parking lot in Dallas, Texas.
All the data can be found here (for both cities): http://bit.ly/hotcartemps
