Course overview
Learners will be taught on a rota on the following topics;
Energy; Learners will become familiar with the different energy stores. Energy transfer between these stores is responsible for all change within the universe. Learners will describe the changes in energy transfers within systems and consider the efficiency of these transfers. Learners will also use equations to calculate the amount of gravitational potential, kinetic or elastic potential energy an object will have. Learners will also discuss the effect of different renewable and non-renewable energy resources and compare their respective advantages and disadvantages. Learners may have to consider social and political contexts behind the decisions to use certain energy resources.
Electricity; Electric charge is a fundamental property of matter everywhere. In this unit we look at the different electrical components; what they do and what their symbols are. We look into what charge, current, potential difference and resistance is, focusing on ohm's law. We look at how series and parallel components affect the current, potential difference and resistance for different components in a circuit. Lastly, we look at how different components affect resistance such as the length of a wire and lamps. Triple students then go to look at static electricity, including how rubbing insulating materials together causes the transfer of electrons. They will look at how charged objects create electrical fields around themselves.
