Mummifying Hot Dog experiment.

This week we have been learning about the ancient Egyptians and the art of mummification. To show what effect mummification had on the body we are using baking soda and hot dogs to demonstrate this. This experiment takes 14 days to complete. 


On day 0 we measured the length, circumference and weight of the hot dog and observed what it looked like. 

On day 7 we repeat the measurements and observe the changes.

On day 14 we repeated the process.

We found out that mummification shrinks the body and dries it out. This is how they have been preserved for thousands of years!

mummy is a corpse whose skin and flesh have been preserved by chemicals or by exposure to the elements of weather. The ancient Egyptians believed that preserving the body was important because without the body, the previous owner's "ka," or life force, would always be hungry. It was important for a person's ka to survive so that he or she could enjoy the afterlife, or life after death. The ancient Egyptians started mummifying remains about 3500 BC.
