audrey participated in her school's science fair. she wanted to study minerals so we made geodes.
she learned what geodes are and how they form. what egg shell geodes are and how they form. we also experimented with different ingredients to see which one would make the best crystals. we tried baking soda, epsom salts and alum powder.
painting the egg shells (that grammy cracked so carefully for us, thanks grammy) with glue and then sprinkling the ingredient (baking soda, epsom salt, or alum powder)
baking soda
epsom salt
alum powder
the finished project
