Today in Year 5 we have been training to be Scientists. Dr Rigby came from Lancaster University to teach us about bacteria in the digestive system. We used microscopes to look at the intestine of a mouse and found out about good and bad bacteria and why we need both of these in our gut. 
Luke and Ella ( who are both studying at the University) also came with Dr Rigby to share their knowledge and help us make mucus ( snot ). Mucus is really important. It helps to defend us from germs that we could breathe in.
