- Unlike animals plants do not have to feed on other organisms. They collect energy from the sun and build most substances needed to grow by themselves. This process is called photosynthesis and is one of the most important processes on earth. It maintains the gas balance in the atmosphere and is the basis of most food chains.
- Through a range of experiments, modules 1-5 introduce children to the idea that “air” consists of different gases, plants role as oxygen producers and their capacity to absorb carbon dioxide.
- Modules 6-10 address photosynthesis in terms of plant growth as the observable result. Understanding how plants collect sun energy and change it to organic substances is crucial to grasp their role as food providers.
