Students should understand that waves interact in a number of ways with objects and other waves. Students can apply the idea of waves to explain a number of situations. Students to know that sound is a vibration.

2 Students to understand how the vibration propagates. Students can explain why sound travels at different speed through different materials. Students know that sound waves can be represented on an oscilloscope. Students should understand how to interpret different waveforms on the oscilloscope. Students apply the ideas of waves to longitudinal and transverse waves. Students know that gravity is an attractive force and is different on different planets. Students understand and can calculate weight on planets. Students can apply the formula to different situations and explain why the force is different from different objects.

3 Students to know that sound travels at 330m/s through the air. Students to understand how to measure the speed of sound. Students can explain how to improve the measurement of the speed of sound. Students know the parts of the human ear. Students understand how the parts of the human ear lead to hearing. Students can explain the effects of ear damage. Students know that the speed of a wave affects the frequency and wavelength. Students understand how to calculate the speed of a wave from the frequency and wavelength. Explain the effect on a wave when the frequency or speed changes.

4 FOUNDATION MIDDLEHIGHERS tudents should know that different foods have different amounts of energy. Students understand how to show that different foods have different energy content. Students are able to compare one food with another and evaluate the results. Students should know the arrangements of particles in solids, liquids and gases and know the transitions between them. Students should be able to explain the properties of solids, liquids and gases by applying the kinetic energy model. Students should be able to give the advantages and disadvantages of analogies to the kinetic energy model.

5 Students should know that some materials are thermal insulators and some are thermal conductors. Students should be able to explain the role of the vibration of particles in conduction. Students should be able to compare conduction in metals and non metals. Students should know which states Students should be able to explain the Students should apply the process of of matter allow convection and be able to describe it. mechanism of convection. convection to a variety of should know that radiation can be affected by the temperature of an object and the nature of the surface.

6 Students should understand which surfaces are good emitters and absorbers of infrared radiation. Students should apply their knowledge of radiation to explain examples such as solar panels and solar cookers. Students should know that changes of state add or remove energy from atoms. Students how evaporation of particles causes a cooling effect Students should apply their knowledge of evaporation and condensation to examples. Students know the different types of energy and know that energy changers can transfer energy from one form to another. Students can explain which energy changer produces which sort of energy.

7 Students can further apply the idea of wasted or unwanted energy to energy changes. Students should know the meaning of the term efficiency. Students should understand how to calculate efficiency. Students apply the idea of efficiency to energy and power calculations. Students should know what a Sankey diagrams is and what it represents. Students should understand how to interpret and use Sankey diagrams. Students should be able to apply a Sankey diagram to an energy transfer system. Students should know the difference between energy and power. Students should understand how to change calculate energy from power.

8 Students should apply power rating to energy use by appliances. Students should that fuel and electricity costs money. Students should understand how to calculate energy costs. Students should compare different costs of energy. Students should know where electricity comes from. Students should understand the different parts of a fuel power station. Students should be able to compare different power generation methods. Students should know that some materials can be used to store heat energy. Students should understand how to investigate which material can store the most heat energy.

9 Students should know the applications of specific heat capacity. Describe the nutrients the body need and their role within the body. Explain the role of nutrients within the body and examine food labels. Explain if the foods are healthy or unhealthy according to their nutrient contents. Analyse the role of thenutrients that make up a balanced diet. Analyse food labels and conclude whether foods are healthy or not in regards to its fat/sugar content. Link an unbalanced diet to health issues. Recall tests for some food groups. Can carry out these tests with help and can make predictions about obvious foods.

10 Explain how to test for all nutrients. Can carry out these tests and can make predictions about the nutrients within foods. Explain and analyse tests for all nutrients. Can carry out these tests confidently and can make use of the information to plan an investigation to find out what nutrients are in a mystery food. Describe why hand washing is important Explain an experiment to demonstrate the effect of hand washing on bacterial growth Make links between hand washing and the pread of MRSA Describe what is meant by a communicable disease Explain how bacteria and viruses cause disease Evaluate the differences between bacteria and viruses Describe how infectious disease can be spread from one person to another.
