Ending the Week

Mr. Chayim Goldberg, who teaches Chemistry and Biology, has begin the tradition of "ending the week with a bang."

He says, "we end our Thursday class with an eye-catching experiment related to what we are learning. This week I was demonstrating how if there is a lot of energy released when atoms gain electrons ("electron affinity") and the energy to remove an electron from the the reacting atoms is relatively smaller, the excess energy can be released in the form of light and heat. This is an example of a spontaneous exothermic (energy-releasing) reaction using an oxidizer, a fuel, and an acid." Photo credit goes to David Pando (Grade 10).
