Last week we followed up a class discussion by taking a look into the worm bins. Our topic this term tracks the journey food takes through our body. We looked into how worms take in food and give out worm poo or worm casts. Did you know...
A worm's mouth parts come out of its mouth to grap food and then pull the food back in.
A worm uses stones to grind food in its gizzard just like some dinosaurs used to.
A worm makes use of saliva to break down food just like we do.
