Here you have the opportunity to deepen their understanding of the nuclear model of the atom, making use of ideas about...
Demonstration: Rutherford’s scattering experiment was an ingenious piece of design and interpretation. Whilst it is not...
Two methods for demonstrating this to your students. Liquid nitrogen presents a particular set of risks.
Demonstration: This introduces students to the idea that the value of a measurement depends on the nature of that measurement.
Demonstration: Finding the thickness of an oil film enables an estimate of the size of atoms to be made.
Demonstration: This helps students to remember that olive oil molecules stick up out of water like grass on a lawn.
Class practical: Experiments to help a class understand the Estimating the size of a molecule using an oil film experiment.
Demonstration: Using models to support a discussion of the mean-free-path of molecules in a gas, and, perhaps, to lead to a...
Students will have seen signs of electrons and positive ions (perhaps carrying a current through ionized neon or helium). On...
Hans Geiger was one of Rutherford’s students at Manchester University. He had been trying to make a workable detector to count...
In this episode, students look in detail at Rutherford’s experiment and relate it to a mechanical analogue.
Having established the existence of the nucleus, you can now consider experimental evidence for its size, starting from the...
