Maths of Digestion: A session of time and distance

Norfolk House invited 5 schools (Rhodes Avenue, St John Vianney Campsbourne, St Martin of Porres and North Haringey) to join us in a fascinating master class about the journey of a biscuit through your digestive system. As a starter, Mrs Holt gave us a warm up by testing us on some questions about the maths of digestion. Did you know that the area that the digestive system would take up if it was stretched out (in square metres) is 30 metres?

We then proceeded onto Challenge 1 for which we were provided with a washing line, some pegs and cartoon pictures/words of our digestive system we had to peg all the pictures/words onto the washing line in order of the path of our food. Then we had to put the cm of each part down to denote the distance that food travels.

Next, we all had to eat a biscuit and time ourselves. We had to work out the average time it took us to eat a biscuit on our table. We could do this as a mean, median or mode. We decided as a team that the mean is the most accurate in our situation as the chance of a mode is unlikely and the median isn’t the middle between all the times that we took on our table. Of course after that we worked out the average.

Armed with this data we could use the time and the length to work out the distance from entry and the time we took in total. On our table we worked out that a biscuit travels 823cm and takes 1441.15 minutes to be fully digested. We then plotted this on a line graph and were clearly able to see which part of the digestive process was the fastest,

This master class was great fun and I felt that through working collaboratively, I learned a lot about the Maths and Science of Digestion
