All plants remove carbon dioxide from the atmosphere, mainly through their leaves – as part of their food-making process – photosynthesis. Trees are our largest plants and therefore remove far more than other plants. In fact – forests store 86% of the planet’s carbon, outside the oceans and Earth’s core.
This activity sets out to explore how leaves go about their most important mission in life – carbon capture, finding out the key players and processes.
Learners will have/be able to:
- Describe the role of leaves as the food factories of trees, and one way of removing carbon dioxide from the atmosphere
- Describe the different steps involved in the process of fixing carbon in plants, mentioning key materials and gases
- Explain why plants are the source of energy for most living things, and are important in reducing the impacts of climate change
- Participated in a dramatisation of the process of photosynthesis
- Recognised how re–enacting the process of photosynthesis helps understanding how it works.
