Discovery 4-1 Atomic Emission Spectra
In this emission spectra worksheet, students use a spectroscope to observe three types of spectra. These include continuous spectrum, emission spectrum and absorption spectrum.
Curated OER
Mass Spectrometer
In this mass spectrometer worksheet, high schoolers read about how a mass spectrometer determines the elements in gases around Earth. Students answer 3 questions and identify the elements in a graph found by a mass spectrometer.
