GCSEphysics

GCSE Core Science: Physics

B: Minor risk from hot objects (burns)

E: minor risk from electrical equipment

N: no significant risk

S: specific risk assessment

H: minor risk from heavy objects

In year 10, students are usually split into three groups: 10Y is the single science group. The double science group is split into 10X and 10XX. Homework

Students are given the chapter from the book. They are asked to read it, make notes on it and answer all the questions. They are also occasionally asked to complete classwork and plot graphs. During outings week they are asked to research their ISA Hypothesis and complete the Research notes sheet. Textbook: Nelson Thornes: AQA Science A; Jim Breithaupt et al.

Lesson allocation: 2 ´ 80 minutes per week for one term (in rotation).

Homework allocation: 2 x 30 minutes per week

1 1.1 Infrared radiation: infra red radiation is the transfer of energy by electromagnetic waves. All objects emit and absorb infrared radiation. The amount of infrared radiation increases with the temperature of the object.

1.2Surfaces and radiation: Matt black surfaces are the best absorbers and emitters of infrared radiation. Shiny surfaces are the worst emitters, worst absorbers but best reflectors of infrared radiation.

E 2 1.3 States of matter: Solids, liquids and gases have different properties. The arrangement of particles in solids, liquids and gases give rise to their properties, eg density, ability to float etc 1.4 Conduction: Conduction is a process of energy transfer by heating. Metals are good conductors because they have free electrons that carry energy. Non-metal solids are generally poor conductors because they rely on atomic vibrations to carry energy.

3 1.5 Convection: Convection currents are the movement of particles in fluids. How convection currents carry energy in fluids. Expansion and changes in density cause convection currents. 1.6 Evaporation and condensation: Evaporation is the change of state from liquid and gas. The reverse is condensation. How to increase and decrease evaporation and condensation. Cooling occurs during evaporation. 1.7 Energy transfer by design: Factors that affect the rate of energy transfer. Ways of controlling the flow of energy. How to increase or reduce the rate of energy flow. Plan investigations in the rate of energy transfer. Model of a room with a candle to show convection

4 1.8 Specific heat capacity: Energy required to increase the temperature of an object depends on its mass. Each material has a differ4ent specific heat capacity. Storage heaters store and release energy. 1.9 Heating and insulating buildings: Various methods of reducing energy flow from a house. Insulating properties can be measured using U values. Solar heating has no fuel costs but can be initially expensive. Finding the specific heat capacity of water.

Wasted heat energy spreads around and is no longer useful. 2.4 Energy and efficiency: Efficiency means how effective is a machine in doing useful work. How to measure the efficiency of a motor. How to calculate the efficiency of a range of devices. How can we reduce energy consumption.
