Do an Archaeological dig in your closet!

Materials Needed:

• Notebook

• Pen or pencil

• Full dirty laundry basket (or maybe just a pile behind your bedroom door).

Get Started:

• Remove pieces of laundry one at a time. Record everything that comes out in order.
• Make sure you take things out in horizontal layers from the top of the pile to the bottom.
• Describe each item in detail.

What does this mean?

• Geologists and Archaeologists use the Law of Superposition. This means that whatever they find on top (geologists=rocks, archaeologists= human artifacts like pottery and tools) is newer than what is underneath.
• The laundry at the top of the pile was worn more recently than the laundry at the bottom of the pile.
• This way you know what you wore at the beginning of the month and at the end of the month.
• Archaeologists know what tools were used before others and how they changed.
• Geologists study which rocks are older than others and what it means in regards to the rest of the Earth.
