People are still discovering artifacts from the past, like a 900 year old Crusader sword found in shallow waters off the coast of Isreal. You might wonder:

• how can they know which group of people the sword belonged to?
• how can they estimate how many years old the sword is?
• what are the ways they can use to measure the age of it and how accurate can they be?
