The symbol equation for photosynthesis is:
CO<SUB>2</SUB> plus H<SUB>2</SUB>O -> C<SUB>6</SUB>H<SUB>12</SUB>O<SUB>6</SUB>
With a wavy arrow showing the light energy. |
|
What is the symbol equation for photosynthesis? The wavy arrow distinguishes between the Big Ideas of Particles and Energy. |

| A |
Students can identify the number of elements in a compound from its formulae. -
Students can identify the number of atoms in a compound from its formulae |
|
For each chemical in photosynthesis eg:
Carbon dioxide is made up of the elements of Carbon and Oxygen.
The molecule consists of three atoms. |
|
|
| A |
Chemical reactions result from the rearrangement of atoms. |
|
What happens to atoms in chemical reactions? Use the chant and Particles -
Chemical writing frame to explain what is happening:
- Molecules (Hands make fists)
- Collide (Bag fists together twice, sticking together the second time)
- Split (Spread fingers out)
- Rearrange (Slide hands one in front of the other, then the other way round
- Bond (interlock fingers)
- Become a new substance (roll hands to 'present' new substance) |

DESIRABLE:
No particles are created or destroyed in a chemical reaction.
Therefore the equation needs to be balanced. |
|
What happens to the numbers of each atom in a chemical reaction? |
|
|
| A |
Photosynthesis is an endothermic chemical reactions because it takes energy to build bigger molecules. |
|
What makes photosynthesis an endothermic reaction? Energy ENters in ENdothermic reactions |

The symbol equation for respiration is:
C<SUB>6</SUB>H<SUB>12</SUB>O<SUB>6</SUB> -> CO<SUB>2</SUB> plus H<SUB>2</SUB>O
With a wavy arrow showing the energy leaving the reaction. |
|
What is the symbol equation for respiration? |
|
|
| A |
Respiration is an exothermic chemical reactions because it releases energy when bigger molecules are split. |
|
What makes respiration an exothermic reaction? Energy EXits in EXothermic reactions |
