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 buret tubes needed for these labs, but now we hope 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.

Six years ago, a local university donated 20 used iMac computers to my lab. Then, 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 temperature, pH, and electrical conductivity by computer.

Also thanks to donors we have some probes that can count and record drops of chemicals, but we still need four more so all student lab groups can participate. With the probes, computers counter probes directly read and save the data for them, while students can focus 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.
