 Apple Mummification
 Ancient Egypt: Social Studies, Math, Science
 Upon completion of this lesson, students will be able to conclude which salt compound removed the most moisture from the apple and which preserved the apple the best without it rotting.
 Students will work cooperatively in groups
 Apples, cups, salt, epsom salt, baking powder, beakers
 During the mummification process, embalmers would cover a body with a salt compound they found along the Nile River called natron.This compound would pull out any of the moisture from the body to allow for better mummification and keep it from rotting.
 Students will first hypothesize which salt compound will pull out the most moisture from the apple. Procedure: Weigh each slice of apple and record In each cup there should be a slice of apple with the before weight recorded and the salt compound recorded Cup 1: Salt Cup 2: Epsom salt Cup 3: Baking Powder Cup 4: 1/2 salt and 1/2 Epsom salt Cup 5: 1/2 Epsom Salt and 1/2 Baking Powder Cup 6: 1/2 salt and 1/2 Baking powder Cup 7: 1/3 salt, 1/3 Epsom, 1/3 Baking powder Cup 8: Control Let the apples stand for 2 weeks After 2 weeks, brush off all salt from the apple Record the after weight and color of the apple Students will subtract the weight and average the weight now of the apple Graph their results
 Students will work with a group of students. Students that need extra help are paired with other students
Checking For Understanding:
 Travel from group to group to make sure all are on track and to check for understanding of the procedure
 Which compound(s) removed the most moisture from the apple Which apple is looks to be the most preserved?
 Graphs Data Gathered
Teacher Reflections:
 This lesson is a great lesson and the kids love it. The only thing that I have found that I have to watch for is that the students follow the steps. They MUST record their weight before they put the salt compound on the apple. They must be sure to put the correct salt compound mixture in the correct cup.
