  • Heating and Cooling is a Physics topic and like many other physics topics we are trying as much as possible to simplify them and make them accessable. If you have another way of really simplifying this topic please e-mail our team at the address shown below

    Slides for lesson 2 to lesson 7 will be uploaded as soon as possible. However visit or e-mail to see slides or obtain further information.

  1. 1. HEATING AND COOLING Aims 1.To know what temperature is 2. To distinguish between heat and temperature. 3. To recognise the need for temperature scale
  2. 2. 3 MINUTES STARTER ACTIVITY Students to have general discussion on the concept of &quot; temperature .&quot; <ul><li>Volunteers to feed back answers after 3 minutes </li></ul><ul><li>What is temperature? </li></ul><ul><li>How do things get hotter or colder </li></ul><ul><li>Task is a survey of student's perceptions/understanding of concept of temperature and heat </li></ul>
  3. 3. Copy out and process the key concepts in the information by rearranging or connecting them. <ul><li>As substances get colder </li></ul><ul><li>As substances get hotter </li></ul><ul><li>The molecules vibrate less </li></ul><ul><li>The molecules vibrate more </li></ul><ul><li>Temperature increases </li></ul><ul><li>Temperature decreases </li></ul><ul><li>This task encourages students to think creatively through reasoning and processing information. </li></ul>
  4. 4. Definition of Concepts <ul><li>We are just beginning to realise the differences between heat and temperature </li></ul><ul><li>From your answers see if you can decide what the unit of </li></ul><ul><li>1. Heat and 2. Temperature are </li></ul><ul><li>It is important we find a way of distinguishing between temperature and heat </li></ul><ul><li>Checking progress through their knowledge and understanding </li></ul>
  5. 5. GETTING HOT OR COLD <ul><li>Can you think of examples of heat transfer in everyday experiences? </li></ul><ul><li>What happens to the temperature of a glass of fizzy drink when you put an ice cube into it? </li></ul><ul><li>What happens to the temperature of the ice cube in the glass of fizzy drink? </li></ul>This task considers the idea that energy transfer results from a difference in temperature. This is an important concept for the students.
  6. 6. TEMPERATURE AND HEAT <ul><li>Temperature is not the same thing as heat –True or False </li></ul><ul><li>Explain the difference between heat and temperature. </li></ul><ul><li>The unit also helps pupils distinguish heat (energy) from temperature. </li></ul>
  7. 7. TEMPERATURE SCALE <ul><li>Copy the Table below and rearrange the information provided in the column titled Object </li></ul><ul><li>Suggests a unit for the column titled Temperature </li></ul>Developing numeracy skills through obtaining, recording and analysing data Boiling point of Water 27 Ice 37 Classroom 0 Human Body 100 Object Temperature
  8. 8. TEMPERATURE SCALES From the scientific point of view how important are temperature scales
  9. 9. AMOUNT OF HEAT ENERGY IN A SUBSTANCE <ul><li>Your task is to draw the following </li></ul><ul><li>1)a beaker full of water 2) a bucket of full of water </li></ul><ul><li>Can you guess why it will take less than 6 minutes to heat the water in the beaker to 40 degree Celsius and nearly an hour to heat the water in the bucket to 40 degree Celsius. </li></ul>
  10. 10. AMOUNT OF HEAT ENERGY IN A SUBSTANCE <ul><li>The amount of heat energy in a substance depends on three factors. </li></ul><ul><li>Can you guess what these factors are </li></ul>
  11. 11. AMOUNT OF HEAT ENERGY IN A SUBSTANCE <ul><li>The amount of heat energy in a substance depends on three factors. These are </li></ul><ul><li>The mass of the substance </li></ul><ul><li>What it is made from </li></ul><ul><li>The temperature of the substance </li></ul>
  12. 12. HOMEWORK <ul><li>Draw arrows showing the direction of energy flow or heat transfer in the following </li></ul><ul><li>A glass of fizzy drink when you put an ice cube into it </li></ul><ul><li>A cup of tea on a table </li></ul><ul><li>Research the following: </li></ul><ul><li>1) Conduction 2) Convection 3) Radiation </li></ul>
