Objective

By the end of this lesson, the student will understand the process of mummification, learn how different substances like salt, Epsom salt, and baking soda can affect the preservation of organic materials, and conduct a fun experiment to mummify apples.

Materials and Prep

• 2 apples
• 1 cup of salt
• 1 cup of Epsom salt
• 1 cup of baking soda
• 3 containers (to hold each substance and the apples)
• Measuring cups
• Paper towels

Before starting the lesson, make sure to explain the concept of mummification and why ancient cultures used it. Prepare a clean workspace for the experiment to ensure safety and cleanliness.

Activities

1. Introduction to Mummification:

   Begin the lesson with a short discussion about what mummification is and its historical significance. Explain how ancient Egyptians preserved bodies to prepare for the afterlife.

2. Experiment Setup:

   Have the student measure out 1 cup of salt, 1 cup of Epsom salt, and 1 cup of baking soda. Place each in separate containers. Then, let them place one apple in each container, completely covering the apples with the substances.

3. Observation Journal:

   Ask the student to create an observation journal. They can write down their predictions about what will happen to each apple over the next few days and draw pictures to illustrate their thoughts.

4. Daily Check-Ins:

   Over the next week, have daily check-ins to observe the apples. Discuss any changes they notice and encourage the student to document their findings in their journal.

Talking Points

• "Mummification is a way to preserve bodies so they don't decay. Why do you think ancient Egyptians thought this was important?"
• "Salt, Epsom salt, and baking soda can help draw out moisture from the apples. Why do you think removing moisture is important for preservation?"
• "As we check on the apples each day, we will be scientists observing changes. What do you think might happen to the apples?"
• "This experiment is a fun way to learn about chemistry and biology. How do you think the different substances will affect the apples?"
• "After the week is over, we can compare the apples. Which method do you think worked best for mummification?"
