★ Can you describe what you can see?
★ Why do you think this is happening?
★ How do you know that?
★ If you wanted to make this rock sculpture higher, what sorts of stones would you add? Think about the size, weight, shape and type of stones you could use.
★ If you had to make the tallest rock sculpture possible with 10 stones, which sorts of stones would you pick? Think about the size, weight, shape and type of stones you could use.
★ As part of a team can you design the tallest rock sculpture and make it happen? Was your team’s sculpture the tallest in the class? Swap stones with another group. Can you make a taller sculpture than they made with their stones? What did you differently? What did you do the same?
★ Based on your experiments can you come up with a strategy for building the tallest sculpture from stones?
