Celebrating Hispanic & Latinx Heritage Month

Celebrate Hispanic & Latinx Heritage Month

This project is a part of the Hispanic & Latinx Heritage Month celebration because it supports a Latino teacher or a school where the majority of students are Latino.

My Project

If you have ever been in a Chemistry class or seen one on TV, you have probably watched students carefully mixing colorful chemicals from long measurement tubes. These traditional experiments, called "titration" labs, require students to analyze and identify unknown chemical substances. Our class has the long buret tubes needed for these labs, but now we need to add in technology to upgrade our labs for a more modern, computerized experience, like the labs they will have in college.

If my students can receive Vernier computer-linked "drop counter" probes, it will modernize their titration labs as they analyze and identify unknown substances, helping them to develop crucial skills required for college and careers in medicine or science.

Buret tubes are manufactured and marked with lines so that a student can read exactly how much liquid is dispensed when performing a lab analysis. With Vernier drop-counter probes, students will be able to perform titrations with much more precision and in a shorter amount of time.

Five years ago, a local university donated 20 used iMac computers to my lab. And thanks to contributors through DonorsChoose, over the past years we have received many computer-linked probes to attach to these computers, much like the digital thermometers used in your doctor's office. Students can measure things like temperature, pH, electrical conductivity, and gas pressure using sensors that connect directly to a computer.

With the help of drop counter probes, students will not have to spend so much time reading and recording titration measurements, the computers will directly read and save the data for them, so students can focus more time on developing their analysis skills.

To keep our Chemistry lab up to date, our public school must rely on donations and grants. So any amount you might donate would be greatly appreciated.
