If I remember from primary school - many years ago - runner beans were grown so we could see how they developed.
Buy a packet of beans suitable for growing from a garden centre or most supermarkets. This cannot be avoided.
1 You can split a bean to show its various parts.
2 Place a cylinder of blotting paper (I'm sure they still sell it) in a glass vessel with water at the bottom and place an undamaged runner bean seed between the glass and the blotting paper. It will germinate and grow. It can be observed and drawn if the children are of a suitable age group.
3 Plant beans in pots - perhaps one per child - with compost and name label + spares so the children can grow them ready to plant out in the garden or bigger pots once the danger of frost is over.
Don't forget to take photos at every stage.
Good luck and happy growing.
