Today in science club we have been learning about nutrition for plants. Plants get nutrition by soaking up water through their roots. The water travels through the veins in the plant up to the leaves.
We set up an experiment to show how water travels in plants We put food colouring in water - 1 red jar and 1 blue jar. Then we split the celery stalk in half up the middle and put 1 end in the blue water and one end in the red water.
We observed that the red water travelled up the stem through the xylem tubes to the veins in the leaves. The blue was only just starting to show.
We also went for a walk to gather different sorts of leaves. We grouped them into categories by looking at their shape, texture, size, veins and edges. We noticed that the veins in leaves look different. Miss Harrison told us that leaves can be grouped by the pattern of their veins.
Palmate leaves - have several main veins that branch out from the base of the leaf.
Pinnate leaves - have 1 main vein running down the leaf.
Parallel vein leaves - have all the veins running in the same direction.
