Water Transportation Experiment

Recently, in 3V we have been looking at the secret life of plants.  We have been learning all about how plants stay alive, including looking at the way in which they adapt to different surroundings.  We learnt how plants growing in desert conditions conserve water, and how plants growing under the dark rainforest canopy manage to maximise their exposure to light.


This week, we have been looking at the inside of plants, and how they transport nutrients and water from their roots to their leaves.  We have been practising our scientific thinking skills in order to design an experiment to try to prove that water travels up the stems of plants.  

To do this, we carefully measured out plain water and dyed it blue with food colouring, before adding a stick of celery to the water.  In order to keep the experiment fair, we have also put a stick of celery in the same amount of plain water to see whether the results are different.  This is called the 'control.'

We are hoping that the celery will turn blue as the dyed water passes through the stem - we'll keep you updated!
