We moved on to the digestive system and created a "stomach" with a paper tube and poly bag filled with water. We "fed" it with some bread so that we could get the idea of food being broken down by acid in the stomach.
We tried to look at fat globules in milk but our microscopes were not powerful enough. Instead we made a "lava lamp" with coloured water and oil to show what it might look like.
The addition of fizzy alka seltzer made an interesting effect in the bottle.
We are even growing a brain in the classroom!
This looks like fun, although, a bit yucky! Hope you learnt lots about the human body and how it functions. It's a tricky mechanism. Caroline(Laura's mum)
