1st Guest Scientist-In-Residence At Irchester – Dr Erinma Ochu

On Tuesday 11th November, Dr. Erinma Ochu, a Wellcome Trust Engagement Fellow, was our guest scientist-in-residence. She is currently exploring how the public can participate in biomedical research, and came into the lab to help some of our children answer questions they had about their teeth.

We had to bring our toothbrushes to school. When we put the purple tablets in our mouths, they turned our mouths purple.  We put the tablets in to show how much plaque we had.   Plaque is bacteria which we have to brush off.  Then we drew a tooth and labelled it. We learned that teeth do different jobs and teeth are different shapes and sizes. There is a tooth called a molar.  At the end, we did a quiz all about teeth and Denominator team beat Supercats team.

‘My favourite bit was using the purple tablet, although it tasted like chalk.’ Freddie, year 3.

‘I liked seeing how much plaque was on my teeth,’ Lily, year 3.
