Practical Physics. This website is for teachers of physics in schools and colleges. It is a collection of experiments that demonstrate a wide range of physical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians.
Physics is a practical science. Good quality, appropriate physics experiments and investigations are the key to enhanced learning, and clarification and consolidation of theory. We have published a new set of resources to support the teaching of practical science for Key Stages 3-5. The laws list. Real-Life Chemistry Vol 3 - Physics Vol 1. Episode 102: Current as a flow of charge. Here, you are trying to illustrate the idea of electric charge and its relationship to a flow of current. Summary Demonstration: Spooning charge (15 minutes)Worked example: Calculating numbers of electrons (10 minutes)Demonstration: The shuttling ball (15 minutes)Worked example: Calculating charge per second (10 minutes)Discussion: Defining current, the coulomb (10 minutes)Student questions: On charge and current (30 minutes) Demonstration: Spooning chargeStart by reminding your students of the nature of electric charge.
They should be familiar with the concept of charge from pre-16 science course. Use the ‘Spooning Charge’ demonstration to reinforce the idea that charge can be taken from one place to another and does not just disappear. Episode 102-1: Spooning charge (Word, 38 KB) Worked example: Calculating numbers of electronsRemind them that charge is measured in coulombs and tell them that the size of the charge on an electron is a tiny fraction of a coulomb (1.6 × 10-19 C).
