Have you ever wondered…about your teeth?
Have you ever had a tooth pulled out by a dentist? If you did, you may have noticed something odd. The roots were probably still attached to the tooth, unlike when a tooth falls out normally.

A building so remarkable that this one photo cannot hope to do it justice – more pictures here. This is the largest and most valuable collection of Portuguese literature outside of Portugal. The library was constructed between 1880 and 1887 – the facade was carved out of limestone in Lisbon, Portugal and transported by ship to Rio.
How to Negotiate a Later Bedtime
Communication and negotiation are two ways of helping you get what you want, without fighting or arguing with your parents, family or friends or even at school with your teacher. If you communicate and negotiate well, you and the person you are negotiating with can come to a agreement without either of you feeling like you “gave in” or lost the argument.
It’s genetic, isn’t it?
Genetics is the study of how genes are inherited in a population. A scientist interested in genetics is a geneticist. If something is genetic, that means it is passed to you by your Mum and Dad. You inherit genes from your parents.
Genes control most aspects of human life, from eye colour to how fast you can run. There are some fun ways to demonstrate genetics in your own family.
Take tongue rolling. The ability to roll your tongue is what we call a dominant trait. If you have the gene for tongue rolling you will be able to roll your tongue.
