Kauri dieback experiments

On Tuesday, 11th August, Room 2 participated in two experiments to learn how a plants roots transport water through them and the effect that the Kauri dieback disease has on the trees.  Below are some photos from the experiments.

Room 2 shared their prior knowledge.

Looking at the "roots" within celery.

Observation sheet.

 At morning tea we drew our observations into our sheet.  We noticed that the ends of the celery were turning red.

We drew our new observations at lunch time.  Look at how the red dye is travelling up the celery and that the leaves were tinged with red. 

 Look at all the red in the celery leaves!

We then wrote about our new learning.  Have a read...

The leaves are red and celery is in the dye.  It sucks the water and the tree turns red.

The fruit die because there are holes in the straw (roots).  The fruit sucks the water and the fruits die because they can't get enough water.

The trees need to drink water with their roots.  Kauri dieback hurts the kauri trees.  Some roots have holes from the germs, we drew these like pacman and water comes out.  The trees slowly dies.

We were doing an experiment and the roots turn red in the food colouring and die.  When the germs come, they attack the roots and make holes in the roots.  When the roots suck up the water it will fall out and the plant will die.

This is what Kauri dieback disease does to the roots.
