Curated OER
The Flame and the Atom:
Students investigate the structure of atoms. Students read information about the Rutherford model, the Bohr model, and the Quantum Mechanical model examining each for its scientific validity. They watch a PowerPoint presentation of alpha...
Curated OER
The Day the Atom Died (Grade K-1)
Students investigate what is wrong with the Rutherford atomic model. For this chemistry lesson, students answer questions about the atomic model after watching a video. They draw conclusions from the video and discuss how the atomic...
Curated OER
Grating Spectrometer
Students calculate the Balmer series. In this physics lesson, students observe hydrogen lamp spectra using spectrometers. They calculate wavelength and compare them with their theoretical calculations.
Curated OER
Quantum Mechanics and Atomic Physics
Students will discuss the de Brogile Hypothesis and state the circumstances under which the wave nature of matter is observed. They will also calculate the wavelengths of matter waves.
Curated OER
Angular Solution of Hydrogen Atom
Students participate in an angular solution of hydrogen activity. Using this activity, students also illustrate eigenvalue problems applied in mathematics. They explore Schrodinger's equation and particle wave duality.
Curated OER
Energy Dispersive Spectroscopy
Students calculate the values of electron binding energies. In this physics lesson, students solve for different wavelength characteristics of X-rays. They present their findings to the class.
