We did an experiment to find out our lung capacity. We had to get a long pipe, a milk bottles, lots of water and a big bucket. We blew into the pipe which showed how much air we had in our lungs. Alice had the most – 1800ml! It was fun and interesting!

Eating crackers are impossibly hard to eat without water because the saliva in your mouth can’t produce quickly enough to swallow. So, you’re left with crumbs in your mouth!
Today we did an experiment on the digestive system!
First, we added banana and cornflakes into a bowl which represented our mouth,
Next we added water which represents saliva which contains enzymes which help to digest our food.
Next we added the mixture to our sandwich bag which represented our oesophagus and added coloured water which represented different enzymes.
Then the mixtures was pushed by muscles into our stomach and churned around.
Then it went into our small intestine (which is actually the longer one!) and water and nutrients were absorbed into the bloodstream (the bowl.) Next, it went to the large intestine and excess water was removed.
Finally, the waste product was pushed out into the bowl – look at our faces!

What a beautiful day it has been today! P5-7 made the most of the lovely weather and practised their spelling words outside.
