Here is part of the conversation between a group of children as they discuss a tall tree nearby:

"I wonder how tall it is?" says Linus.

"I think we could find out," replies Raj.

"It could be difficult as it's very high," says Toby.

I wonder how they each went about finding out the height of the tree?

I wonder how YOU would find out how tall a large tree in your surroundings is?
