Archer’s annual STEM Symposium is an opportunity for Los Angeles high school students who have completed independent or small group projects in STEM to present their findings. Students are invited to present their research in the fields of molecular biology, chemistry, physics, and engineering.

The Archer RISE Award honors exceptional young women for their innovative scientific research or engineering design projects that further existing knowledge or develop solutions to pressing scientific challenges. Finalists for the RISE Award are noted in throughout the online program and will be awarded at lunch on May 21.

Construction & Analysis of a D.I.Y. Spectrophotometer: Can I get a Watt Watt?

A spectrophotometer is an integral part of a traditional chemistry course for most high school students. It is a tool that measures absorption of visible light and is used by scientists in real world situations including, but not limited to, research in the life sciences, chemistry, and deep-sea exploration. Depending on the capabilities, however, the price for a spectrophotometer ranges from a few hundred dollars to tens of thousands. Our goal is to replicate an experiment to build a spectrophotometer utilizing Apple technology (iPhones & iPads) and Windows software, which are more accessible and cost efficient to schools that lack the funding for a standard spectrophotometer. Once we have built the spectrophotometer, we plan to run multiple experiments to test the precision and accuracy of our instrument in comparison to a standard classroom spectrophotometer. We will also conduct a detailed cost analysis of typical classroom spectrophotometers compared to our home-made version. If the iPhone/iPad is able to complete experiments with just as much precision and accuracy as the spectrophotometer, students around the world will be able to access lab experiences that they might not have been able to previously.
