• Please Help Modernize Our Chemistry Lab With Titration Computer Probes

  Funded Nov 10, 2021

  Thank you so much for donating the probes for our experiments. Students have greatly enjoyed being able to start incorporating the computer probes into their Chemistry titrations for redox labs and for acid-base labs.

  Now, we have enough probes for multiple lab stations, so that all students can participate in labs simultaneously. Now, as time is passing by quickly, we just hope to receive some newer computers soon.

  Once again, thank you! We greatly appreciate your generous contribution. Our public school would not be able to have modernized computerized science lab without donations from people like you! With your contributions to our growing labs, we are able to offer students with opportunities to use technology in their science labs that will prepare them for the instrumentation they will use in college and in science careers.

  Thank you!”

• Please Provide Lab Tools For Chemistry Students To Investigate Electrochemistry

  Funded Jun 12, 2022

  Thank you so much for your generous donations for electrochemistry labs. Originally, this grant request was for a Hoffman Apparatus - that is used to electrolyze water - but unfortunately the suppliers were out of stock with a long backorder. So Donorschoose asked me to pick some other related items.

  As you will see in the photos, we purchased equipment to make "batteries" from metals and chemical solutions (We received Leyden Jar, electrochemical cells with porous cups, metal strips and some beakers). My students are extremely motivated and excited for these electrochemistry labs. Now, I will plan to get even more of these cells so that there are enough for all my students in class to work together simultaneously. In these basic beginner labs, students are measuring the different voltages that can be produced between two different metals - like iron, copper, zinc, lead, tin, and magnesium strips.

  Students were excited to see that they could produce electricity from metals and chemical solutions. They observed the different ranges of voltages that could be produced from different combinations of metals.

  We greatly appreciate your generosity in supporting our Chemistry science lab program- all the equipment will continue to go to great use!”

• Please Expand Our Science Lab Technology To Reach More Students

  Funded Jun 28, 2023

  We greatly appreciate your donations to purchase computer probes for my Chemistry students to measure pH and temperature. We have performed several titration experiments this year (namely mixing acids and bases) and the probes, along with the Vernier equipment, makes it easy to read and collect the data.

  Students can focus on data and analyzing data instead of on taking long times trying to read calibrations or to interpret pH color charts on older traditional equipment. For examples, in an acid base titration, the students have performed experiments to analyze and identify an unknown solid acid (by finding its molar mass). Also students have determined the concentration of unknown solutions (standardizing solutions) by using the pH meters along with the traditional colored indicators too (its still fun to see the color changes in a lab).

  Thank you so much for your generosity, with your donations you are making it possible for students to experience using technology as they will soon be doing in their college and careers.”

• Please Help Provide An Electronic Balance for Our Chemistry Lab

  Funded May 22, 2021

  Thank you again for your generous contributions. Because of your gifts, our students of Chemistry and Physics are enjoying an updated, modernized science lab experience.

  The electronic balances that you provided for us are great. These are the best digital balances I have ever used so far in my 20+ years of teaching Chemistry. Also these have the capability to connect to computer via the Vernier interfaces that other donors have made possible for us. We discovered that we will also need some cables for that to happen, but I am working on that right now.

  These balances are useful in our Chemistry labs like 1) Determining the chemical formula of an unknown compound (empirical formula) 2) Determining the molar mass (and molecular formula) of an unknown gas 3) Determining the chemical mass (and identity) of an unknown solid acid (we used aspirin in our experiment).

  My students are truly enjoying the technology- I have several students who gladly volunteer to help me set up and clean up the equipment for our lab experiments.

  We greatly appreciate your donations. Thanks to your giving, modern digital scales and computer technology is now becoming a reality in our science lab classroom. We currently have enough equipment to supply about 15 students with a new electronic balance. Now, in the next year, we hope to continue to expand each lab station by purchasing more balances (hopefully up to 4 more).

  Thanks again so much for your donations. With your assistance, you are opening up great opportunities that our students will need as they pursue college and careers in science, medicine, and engineering.”

• Help Public School Expand Our Computer Probes for Chemistry Labs

  Funded Aug 12, 2020

  Thank you so much for your donations to help expand our Chemistry lab with computer probe technology. The gas pressure probes connects to our desktop computers. The students are enjoying the chance to learn to operate the equipment.

  We greatly appreciate that thanks to two Donorschoose projects , we now have enough units for all our class to work in groups simultaneously.

  When a gas pressure probe is plugged into the interface box, students are able to see the real-time progress of their lab experiment. In our experiments, students weighed a piece of magnesium metal, then filled a test tube partially with H2SO4 acid, then they carefully balanced the metal nearly sideways near the top of the tube. Next, they plugged in a rubber stopper connected to the gas pressure probe. As the chemicals reacted, hydrogen gas was produced. As you can see in the photos, some students produced a high pressure of gas (760 torr or 1 atmosphere is normal atmospheric pressure) The groups produced gas going up to 900 and 1000 torr.

  The equipment you helped to purchase will benefit all my current and future high school students: General Chemistry, Honors Chemistry, AP Chemistry, & Physics. Now that technology is transforming college science labs, medical centers, and engineering companies, your donations have surely enabled my high school students to have opportunities to gain experience that they will need in their future schools and careers. Students are excited to use the computer linked equipment- it makes the science labs more interesting to them.”

• Help Upgrade Our Chemistry Lab for All with Computer Probes

  Funded May 28, 2021

  Thank you so much for your donations to help upgrade our Chemistry lab with computer probe units. The Gas Pressure probes connects to our desktop computers. The students are enjoying the chance to learn to operate the equipment. We greatly appreciate that thanks to two Donorschoose projects , we now have enough units for all our class to work in groups at the same time.

  When a gas pressure probe is plugged into the box, students are able to see the real-time progress of their lab experiment. In our experiments, on Boyle's Law, students can change the volume of air trapped in a syringe and then read the pressure changes as they are recorded by the computer. A graph of Pressure vs Time is then made to confirm Boyle's Law.

  The equipment you helped to purchase will benefit all my current and future high school students: General Chemistry, Honors Chemistry, AP Chemistry, & Physics. Students greatly enjoyed using the probes, they were having a contest to see who could apply the highest pressure to a sample of gas (who could compress the gas in the syringe the most).

  Now that technology is transforming college science labs, medical centers, and engineering companies, your donations have surely enabled my high school students to have opportunities to gain experience that they will need in their future schools and careers. Students are excited to use the computer linked equipment- it makes the science labs more interesting to them.

  Thanks again, we appreciate your generous support.”

• Please Provide Our Chemistry Students Burets for Acid/Base Titration Labs

  Funded May 17, 2022

  Thank you very much your donation to my Chemistry lab classroom - it has been a wonderful addition. Thanks to your gift, we now have enough burets for all students to use during our Chemistry experiments. Now that the old broken burets are replaced, my students can now work simultaneously in groups of two or three.

  All the students, mostly eleventh and twelfth graders, are becoming familiar with how to operate and read the burets - developing skills that they will continue to utilize when they enter the college and university level chemistry environments. The lab equipment has been used in an acid-base titration lab and a redox titration lab and will be used in more analysis labs in the future.

  Your support has given my students a valuable, hands on educational opportunity in science that is encouraging for them in these difficult economic times. You have done more than simply maintained our lab, you have improved it. I greatly appreciate your generosity.”
