What you need:

Procedure:
Here are two suggestions for completing the activity:

Option 1: Human Timeline of the Earth-Moon History (for larger, single groups)

  • Share with all participants that they will be using their bodies to create a timeline of the Earth’s and Moon’s shared history.
  • Provide each person with an event card.
  • Invite everyone to work together to determine which events happened first, second, third, and so on.
  • Have them arrange themselves as a human timeline across the room.
  • Compare their arrangement with the answers in the answer sheet.
  • Discuss the information about the rocks. 
    • Which rocks are older, rocks from the Earth or rocks from the Moon?  (The Moon rocks are older.)  
    • How common might old Moon rocks be?  (Very common; most rocks from the Moon are billions of years old)
    • Why might these old Moon rocks be important?  (They contain information about things that happened to the Earth and Moon.)

Option 2: Card Timeline of the Earth-Moon History (for a single or multiple, smaller groups)

  • Divide the participants into groups of 3-5 people
  • Provide each small group of people with a complete set of event cards.
  • Ask the groups to work together to arrange the events in order (floor or table space is needed to lay out the cards).
  • Share the answer sheet so that the groups can compare their results.
  • Discuss the information about the rocks. 
    • Which rocks are older, rocks from the Earth or rocks from the Moon?  (The Moon rocks are older.)  
    • How common might old Moon rocks be?  (Very common; most rocks from the Moon are billions of years old)
    • Why might these old Moon rocks be important?  (They contain information about things that happened to the Earth and Moon.)
