Exploring the Rainbow: Colorful Chemistry 2
Funded Aug 27, 2019Thank you so much for donating to the spectrophotometer project!
In chemistry, we use the color of a solution to determine how much of a specific chemical is present in that solution. Most of us, can look at a liquid and see that if a lot of light that makes it through the sample, we must have a low amount of colored chemical in that solution. A spectrophotometer lets us accurately measure exactly how much light makes it through a sample and figure out exactly how much chemical we have in that sample. Last week, we were able use the spectrophotometers to determine how much blue food dye is present in 2 different sports drinks!
In order to do this, we had to create a standard curve (this is a technique used in the pharmaceutical industry, in water quality analysis and any time scientists need to know how much of a certain chemical is in a sample). All my students were able to generate a linear curve and accurately determine the amount of blue food dye in our samples. This success was a HUGE confidence boost in their chemistry abilities.
Having a spectrophotometer and being able to see how the amount of light that makes it through a sample changes as the amount of chemical in the sample changes really helped students visualize a rather complex concept of concentration.
Next month, we will be learning about the speed of chemical reactions and we will use the spectrophotometers to measure how fast a chemical reaction happens. Last year we had one spectrophotometer and had to do this lab as a demonstration, which did not have the same impact as having the students perform the lab on their own.
My students and I cannot thank you enough for this amazing gift.”

Funded Dec 14, 2019Thank you for funding this project to give students a timer and buzzer system to play Chemistry Review Jeopardy. This setup will arrive just in time for back to school second semester. I will use it to create a welcome back review. It will be an EXCELLENT way to ease students back after the two-week break!”

Funded Jul 11, 2019Thank you so much for funding my Chemistry Speed dating project! This week I was able to convert a boring PowerPoint lecture into group based interactive learning stations!
My students were engaged and loved the material! One student even told the assistant principal about everything she learned and was so excited when she explained the details that my AP had to text me to let me know how excited the student was.
My AP (2nd year chemistry) students had the opportunity to use the plastic trays for their purification experiments this week and they commented how much easier it is to work in the lab when there are designated trays at each station.
My students and I are very grateful for the opportunity to have these new materials.”
