Relaxed Farming - our farm in your classroom

There's a lot of maths (and physics) in an egg: eggs are porous - which means they can let liquid in though tiny holes - these holes are called pores and one egg can have up to 17 000 of them!!

It is hard to crush an egg simply by squeezing it in your hand (go on, dare you), this is because of its curved shape which when you squeeze it means the force of your squeeze is spread out over the whole egg. To break it, just tap a small part with something sharp and hard.

This curved shape also means an egg won't roll in a straight line - try it!!! This is true across most bird eggs and is particularly useful for the guillemot who lays its eggs on a ledge half way up a cliff!!!! Hang on, guillemots are NOT chickens, sorry... back to us chickens

An average chicken egg weighs around 60g - the largest egg ever laid was apparently 340g. Ouch, that must have hurt - makes my eyes water.
