What do plants drink?

The children asked their own questions about plants and we decided to investigate the answer to 'What do plants drink?' 

 

We thought about feeding some plants some different types of drink and observing how it affected the plants' health.

 

These were the healthy plants before we started the experiment.

 

We fed each plant 10ml of liquid each day for a week to make it a fair test. We used orange juice, water, cola and milk. 

These were the results. The plants which were fed orange juice and milk had badly wilted. 

The water-fed plant was looking the healthiest but the most unexpected result was the cola-fed plant. It still looked quite healthy which we did not predict to happen at all. We thought the sugar would damage it straight away! 

Just goes to show that science is not always predictable! 😊
