Every year for our unit on Ancient Egypt, all of my classes mummify apples to simulate the embalming process. The kids always have a great time and can't wait to see their dried up apple "mummies".
I have made a list of necessary materials and detailed the steps below.
Materials needed:
clear cups (I use 16 fl oz) - one per student
apples - eith one per student or one per two students if apples are large
salt
baking soda
tub or bin to put mixture in
scoop or extra cups to scoop with
sharpies
spices like cinnamon, nutmeg, etc (these are totally optional)
apple slicer
small cutting board
Process:
The "day of embalming", I make sure I have all my materials and get my "mummification station" set up. I mix equal parts salt and baking soda together in the tub and use extra cups for scoops. While students are working, I call them back in groups of 3-4 at a time.
Each student receives a clear cup, which they write their name and class period on the side of.
I use the apple slicer to cut the apples and give each student 3-5 slices depending on the size of the apple.
Students put the slices in their cups and use cinnamon, nutmeg, etc. to cover up the smell of the "decaying mummy". This is to mimic how Egyptian embalmers would put oils and perfumes on the skin of actual mummies. They swirl the spices around in their cups to evenly coat their apple slices.
Then students scoop up the mixture of salt and baking soda and add it to their cups to cover their apple slices. The apple must be completely covered. Students may need to tap/swirl the cup to make sure no part of the apple is visible.
Once the entire apple is covered, students place their "mummies" in a section of the classroom where we will leave them for 2-3 weeks. During this time the apple slices will dry out, just like real mummies!
When it is time to uncover the "mummies", I call students back a few at a time and have a trash bag ready. They examine the now dried-up apple slices and identify the similarities and differences between our mummification process and the real thing.
Once students have finished studying their apples, they dispose of them. They do not take them home or eat them (gross!).
I really enjoy this activity. It's a great way for students to learn about the process of mummification and always leads to some really great discussions.
