4. Can you gather around Mr Porter?

5. Aerobic Respiration Occurs in the cytoplasm of cells Glucose + oxygencarbon dioxide + water (+ energy) Reactantsproducts The same reaction as burning, but there’s no flame because the reaction is carefully controlled (slower)

7. Respiration “Snap” cards 1Cut out the cards on Worksheet 8Ba/5 and divide them between you and a partner. 2Each person turns over one card from their pile at the same time. 3Call out ‘snap!’ if one card shows a substance and the other card correctly describes it as a product or a reactant. Remember, energy is not a product. For instance, this is a ‘snap’.This is not a ‘snap’. Glucose reactantoxygenproduct 4The person who calls ‘snap!’ first wins the two cards. These should placed to one side. 5When all the cards have been used, turn over your pile and start again. 6When no more ‘snaps’ can be made, each player should lay out their cards to make the word equation for respiration. Draw in the ‘+’ signs and the arrow. The winner is the person with the most complete word equations.

8. Reading! Can you read pages 16 and 17.
