Dinosaur Excavation in Preschool

Picture 1168We buried dinosaur bones in the sand box. They are actually cow femur bones. To clean them you can boil and then simmer themĀ  for around 24 hours on each side in apple cider vinegar. Just to warn you the smell is AWFUL! and it seeps into everything my house will never be the same. Some butchers have a machine that will completely clean it for you ask around.

Picture 1159The kids dug up the bones and then carted them off to the museum. They then decided which animal each bone went to and sorted them out accordingly!
