Science Week

As part of science week we did some experiments in class. Here is one of them.

 

Did you ever wonder how plants “drink” their water? Plants don’t have any mouth but like us they do get thirsty. Let’s investigate how plants drink water.

Meet our scientists.

 

 

You will need

jar or glass

water

food colouring

flower

a stick of celery

 

 

 Here is a diagram of  plant parts

 

 

We put some flowers in plain water and the petals stayed white.

 

 

We then put some flowers in water with red food colouring. Can you see the difference? Our white flowers are turning red.

 

 

We also put some celery in water with red food colouring. The leaves and stalks turned red.

 This is because the coloured water from the glasses has moved up through the thin tubes in the plants.

We hope you enjoyed our experiment.
