Ever wanted to know how the Ancient Egyptians created mummies? Well the children of Class 4 did and so they have started a scientific experiment to discover the effects of salt on organic materials.
Mrs Rogers brought to school a fish (Tutmose the Trout) and modelled the first stage of the process. Did you know that mummified fish have been found in the tombs of the Pharaohs? First the guts were removed and the insides washed. Then Tutmose was weighed – this was recorded as 270g.
Then the cavity was packed with a mixed of bicarbonate of soda and salt. This mixture was also packed around the outside of Tutmose so he was completely covered.
Human bodies take approximately 40 days to dry out completely; Tutmose will be left until the last week of term. However, every week he will be weighed and any changes will be monitored.
The children then had a try at the process by removing the pulp and seeds from a tomato, weighing it and then packing it with the ‘natron’ (salt) mixture. Just as with Tutmose, they will weigh the tomatoes every week to monitor changes.
