  1. Energy • The ability to do work or cause change Energy= Work

  2. Where does the energy to do things comes from? From the food that we eat

  3. Where do we get the food that we eat? Vegetables, fruits and crops

  4. Photosynthesis

  5. Photosynthesis • is the process by which autotrophic (organism that can make their own food e.g plants)organism use light energy to make sugar and oxygen from carbon dioxide and water.

  7. How do we measure energy? Activity : Experiment on measuring energy we get from burning or eating. We measure Energy in joules (J). A Joule is a very small of energy so energy is often given in Kilojoules 1 kilojoules (kJ= 1000j)
