    A2 Storing heat (teacher instructions)
    Experimentation instructions for Experimento | 10+:Background information on the content and practical information on conducting the experiment "We store heat – From heat store to molten salt". This experiment comprises four subexperiments.Enough apparatus and materials are supplied to allow eight groups of students to conduct the ex-periments simultaneously. When all the subexperiments are conducted in the suggested se-quence, they form a basis for a learning unit on heat, heat storage, temperature, phase transition (states of matter), heat of fusion, and latent heat. These instructions provide explanatory notes and ideas for further study.The experiment comprises four subexperiments:• Water as a heat store – Not only the tea gets cold• Water as an effective heat store – Water can stay hot longer if …• Heat for cold fingers – Is the heat pack a heat store?• How the heat pack stores heat – A salt that changes between solid and liquid statesNotes: • Observe the safety information in the instructions as well as the applicable safety guidelines for your school.• All materials mentioned in the instructions will have to be purchased directly from commercial sources.

    Thermal energy
    Diagram:Formulas for the thermal energy of gases and temperature as a function of their molar heat capacity at constant volume.The thermal or internal energy of a substance is the sum of the kinetic energies of its atoms or molecules. This energy is measurable as temperature. If you supply heat to the substance, the particle speed increases and the temperature rises. In the case of molecular gases, the supply of heat in addition to the translatory motion can excite other forms of motion (rotation and oscillation). This finds expression in the stepped curve of the molar heat capacity (diagram at the right). The molar heat capacity of a substance is the amount of energy required to raise 1 mole of a substance by 1°C. For gaseous substances, the following applies: If the gas particles move only linearly (translation), the amount of heat that is required to raise the gas by 1°C remains constant at 3R/2. In the case of molecular gases, the molecules start to rotate when a specific temperature is reached. In this area (linear increase in the diagram), more energy must be supplied to raise the temperature by 1°C, since the energy goes not only into the translatory motion, but also into exciting the rotation. If all particles are made to rotate, the energy required to raise the temperature by 1°C is again constant at 5R/2. The rise at the point of transition from rotation to oscillation can be explained in a similar way. Information and ideas:The overview graphic summarizes the topic of thermal energy using the example of gases. You will find detailed explanations as well as an explanation of the heat in solid bodies in the guideline “What is energy?"

    A4 Evaporation heat – How to cool with heat (worksheet 1)
    Worksheet for subject teaching in English:For the student experimentation instructions of the same name. Methodology tool: film strip / reading strategy developed by Josef Leisen and Heinz Klippert.Note: This worksheet has been developed especially for subject teaching in English and for language-sensitive subject teaching. It uses the film strip and reading strategy methodology tools developed by Josef Leisen and Heinz Klippert. The film strip supports coherent speaking and the correct chronological and content-related sequence of actions or events. A reading strategy is a sequence or a timetable of mental events with which a particular reading objective is to be achieved (source: Bimmel, 2002). Reading strategies help the students to better understand technical texts and work independently with them.Students whose native language is not English and who do not have strong English skills receive support and training in understanding the technical vocabulary. They work with the specialized vocabulary and in this way acquire the ability to communicate about specific subjects.
