A Project on Roots

Term 3, 2012

The children in Head Starts II launched the project by constructing a simple sculpture of a plant. They used twine as “roots” to anchor the “plant” to the corkboard. Then, they labelled the different parts of the plant.

Moving forward, the children in Head Starts I were surprised to find out that commonly eaten vegetables are Tuberous Roots! They cut the roots to compare and contrast the internal structures. They used the cross-sections to create artistic prints!

Besides anchoring a plant, the children learnt that roots serve another function: they absorb water and nutrients from the soil. The Head Starts teachers demonstrated this process with celery. The teacher added food colouring to the water that the celery was in. After a day, the children could see streaks of colour along the fine lines of the celery stalk. The celery had absorbed the coloured water!

An outing to an Aerophonics Farm showed how some plants can be grown without soil. In other words, amazingly, roots can absorb nutrients and water in the absence of soil!
