Fluorescence In this science experiment, you will boil a leaf in 50-100ml ethanol for 3-5 minutes. The chlorophyll will be removed and will be in solution. Turn off all of the lights and have the kids crowd around. Shine a white light on the test tube of chlorphyll. The light will excite the electrons and […]

High School Resource Semiconductors by PhET This simulation will allow students to experiment with semiconductors and engage in doping them in a virtual setting. They will watch electrons change position and energy level. Using the simulation, students will: -Recognize that the battery is the driving force in a circuit. -Describe how n and p dopants […]
