Lesson details
Key learning points
- Producers make their own food using a process called photosynthesis.
- Photosynthesis can only happen when there is light.
- Photosynthesis is a series of chemical reactions that take place inside cells.
- The reactants of photosynthesis are water and carbon dioxide, and the products are oxygen and glucose (a carbohydrate).
- Photosynthesis involves many chemical reactions; a word summary of the reactants and products is a model of the process.
Keywords
Producer - A producer is an organism that makes its own food.
Chemical reaction - In a chemical reaction, substances are broken down and react to form new substances.
Photosynthesis - Photosynthesis is a series of chemical reactions by which producers make their own food.
Carbon dioxide - Carbon dioxide is a compound made of carbon and oxygen that is a gas at room temperature and a reactant in photosynthesis.
Glucose - Glucose is a sugar (carbohydrate) produced by photosynthesis.
Common misconception
Light is a chemical reactant in photosynthesis and it is turned into food.
Challenge the misconception that light is a chemical reactant in photosynthesis.
