An Hour In … ChemistryStudents present their demos for a challenge
Students in Mr. Jon O’Brien’s Chemistry 1 class participated in a chemistry challenge competition. This challenge consisted of students presenting experiments that showed chemical reactions.
Sophomore Kaitlan Gutierrez presents her demo turning milk into stone. "I turned milk into stone by using simple materials such as milk and vinegar. When I let the certain substance sit out in room temperature for a couple of hours, the milk had succeeded into turning hard like stone," Gutierrez said.
Sophomore Canei Cunningham and Raymond Reyes make observations on the presentations in order to determine a winner.
As a spectator, sophomore Gabrielle Medellin documents the merits of the presenters and their experiments, highlighting opportunities for improvement or making note of strong qualities.
After unveiling the results of her experiment, sophomore Heather Gonzalez judges her peers’ work and offers advice on their presentation skills or analyzes the contents of their discoveries. “I think it’s cool that we are rating other students’ demos and determining a winner,” sophomore Heather Gonzalez said.
Sophomores Jade Balagtas and Alexa Duenas silently pay attention to the presenter, eager to see the reaction from the experiment.
To prevent an extensive mess, sophomore Jakob Aganon conducts his demo outside. “My lab was elephant's toothpaste, and it creates foam and heat,” Aganon said.
Sophomore Jordan Salas checks on his ingredients for his experiment while Vivien Huang rates the demos and presentations. “There’s a beauty to all the experiments and I’m so excited to be able to do mine today,” Salas said.
The experiment that sophomore Joseph Byrd is presenting is liquid magnet ferro fluid. This a liquid that acts as a magnet.
Mixing soda with a chemical can cause all kinds of reactions. Sophomore Mikaela Punsalan is making glow in the dark Mountain Dew. “I combined hydrogen peroxide, baking soda, dish washing soap and glow sticks in order to make it glow,” Punsalan said.
The Coca Cola with mentos demo that sophomore Thomas Pham is doing causes a big foaming reaction. “ It was a really easy and fun experiment to do,” sophomore Pham said.
