Teach pages for topics E.1 to E.5
Teach: Atomic model
In a series of experiments in the early 1900s, Hans Geiger, Ernest Marsden, and Ernest Rutherford made a set of important discoveries about the structure of atoms. What were their experiments, and what...
Teach: EM radiation and the atom
What is an atomic spectrum, and what does it tell us about the arrangement of electrons in an atom?
Teach: Nuclear Structure (by inquiry)
The Rutherford-Marsden-Geiger experiment gives us a good idea about the structure of the atom, but what about the nucleus? This inquiry-based lesson helps students "discover" neutrons, introduces nuclear...
Teach: Quantization (HL)
By quantizing the angular momentum of an electron in a hydrogen atom, we can derive the Bohr energy levels. But what does this mean, and how does it work?
Teach: Photoelectric effect (HL)
Electrons in a metal can be liberated by visible or ultraviolet light. How does this work, and what does this photoelectric effect tell us about the nature of electromagnetic radiation?
Teach: Nucleons and the nucleus
AimstextConsiderationsThe BE curve is another important core concept. I think it is most easily understood by considering pulling a nucleus apart. Where has all the energy gone?
Teach: Radioactive decay
AimstextConsiderationsRadioactive decay is random and spontaneous so you can not predict or influence when it will happen. It's worth highlighting the difference between these words.
Teach: Fission
Nuclear power production brings together a variety of physics concepts and connects to many broader topics. It's a short unit, but a fun one!
Teach: Fusion and Stars
Nuclear fusion is a fascinating power source, and the good news is that the sky is full of nuclear fusion reactors: stars! How do they work?
