Third level 3-02a
I have collaborated on investigations into the process of photosynthesis and I can demonstrate my understanding of why plants are vital to sustaining life on Earth. SCN 3-02a
Learning intentions and success criteria
Learning intentions: • Explain what photosynthesis is and the main processes and chemicals involved in it. • Suggest ideas for experiments to illustrate the effect of photosynthesis on plant growth and provide reasons why plants are vital for life on Earth.
Success criteria: • I can explain what photosynthesis is. • I can explain the main processes involved in photosynthesis. • I know the main chemicals involved in photosynthesis. • I can suggest ideas for experiments to show the effect of photosynthesis on plant growth. • I can give reasons why plants are vital for life on Earth.
Lesson plan Countryside ranger led activities
1. Explain photosynthesis using pictures. Look at leaf structure and colour using picture frames and hand lenses. Time: 20mins.
2. Play ‘Photosynthesis Tag’. This is a high energy running game. Time: 20mins.
3. Hide cards showing everything that plants needs to photosynthesise. Students then have to find cards showing all these requirements in a certain time to survive. Time: 15mins.
4. Divide the students into an even number of groups. Each group is given five minutes to make up a three question quiz about photosynthesis. Pair the groups up and get them to ask/answer questions. Time: 10mins.
Suggested follow-up activities
1. In the classroom carry out experiments based on photosynthesis:

2. Get your students to do calculations to find out how much carbon dioxide they each produce when breathing and how much oxygen they will require over a lifetime and how many trees this equates to. They can start to factor in other things in their lives that produce carbon dioxide such as food production, clothing, transport and buildings.
3. Look further into chlorophyll and why leaves change colour in autumn. Do an experiment to remove the colour from a leaf:
