Developing Compare the temperature rise of water when some fuels are burnt. Identify situations in which energy is stored. Identify situations in which an energy transfer is taking place. Recall the factors that affect the amount of energy needed in a person's diet. Describe the factors that affect body mass. Recall some substances that are used as sources of energy. Securing Explain the differing energy needs of people of different ages and activity levels. Exceeding Calculate the energy requirements for a particular person or activity.
