Investigating Water Transportation
In todays Science lesson we investigated how water transports up the stem of a plant. We used celery to show how blue food colouring in the water could travel up the stem to the leaves to be used by the plant.
Plants need five things to stay alive…
Today, as part of our science topic plants, we created an experiment to investigate what a plant needs to survive.
If a plant is not watered enough, its stem will be fragile and have very dry leaves. It will eventually die. If a plant does not have enough light, it will grow to be tall and flimsy as it searches for light. It will probably die. The roots take up water and nutrients from the soil. Plants take in carbon dioxide (CO2) from the air and convert it into glucose (a type of sugar) to make their own type of food through the process of photosynthesis. If the plant/ seed does not have enough space, it will not grow.
In groups we all planted some seeds. We then put them in different conditions to see if they could live without water or sunlight.
