Title – Easter Egg Geodes
By – Vivian Sullivan
Primary Subject – Science
Grade Level – 5-12

Purpose:

To learn how geodes in nature are formed from minerals and evaporation.

Materials:

• Egg shell halves
• Egg cartons
• Salt
• Boiling water
• Food coloring

Procedures:

• Boil water
• Dissolve ½ cup salt in every 1 cup of water
• Pour the saline solution into each half of egg
• Add 2 drops of any color food coloring
• Allow water to evaporate 2-3 days until only colored salt crystals are left

Conclusion:

• You now have Easter egg geodes!
• The salt and the food coloring represents the minerals in the soil mixed with water found in nature (rain water, etc.).
• As the dissolved salt recrystallized it was mixed with food coloring to form the geode-like crystals found in nature!
