Evidence Revealing the Composition of the Atom
Investigators use indirect evidence to guess what is occupying a sealed box. You could also use a set of plastic Easter eggs to encase the unknown items. Another terrific activity involves having learners drop a pencil on a sheet of...
Concord Consortium
Concentrating Charge and Electric Fields
How did Rutherford determine that the nucleus was the center of an atom? Take a look inside the famous Gold Foil Experiment with an interesting interactive. Learners fire a beam of alpha particles at a nucleus containing variable...
Curated OER
Activity Three -- Rutherford's Discovery (Student Page ) A Lab Experiment in Physics
This discovery student page offers students an opportunity to work as a team to discover the shape of an object they cannot see. It is an experiment which parallels particle physicists dilemma in not being able to see very small...
National Institute of Open Schooling
Atomic Structure
Learners explain historical findings such as Rutherford and Bohr's contributions, explain wave particle duality, and formulate Heinsenberg's uncertainty principle. They also draw s, p, and d orbitals, explain more historical findings,...
Curated OER
Worksheet 4-1 Atomic Spectra
In this atomic spectra worksheet, students answer eighteen questions about wavelengths of light, the emission spectrum, energy of photons, the frequency of electromagnetic radiation and electrons in the excited state.
Curated OER
Hydrogen Powered Cars
Students apply the principles of chemistry to investigate the concept of how a hydrogen powered car works. They study the electrochemical reactions that provide the energy source. Students also record observations in the functioning of a...
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
Quantum Physics
Students discuss the mass-energy relationship based on Einstein's work. They calculate the energy released in various scenerios and sketch diagrams for the Lyman, Balmer and Pfund Series. In groups, they discuss the role of photons and...
