Science Master Special – Measuring the height of a tree using a pencil and a friend

Now and again I will mention some magical experiences.

This  was a technique given to me by a teacher at Severne Primary School in Birmingham.

Do you want to measure the height of a tree and all you have is a friend and a pencil?

First task line up the vertical pencil with a tree.

Fourth task. Ask the friend to walk from the base of the tree to the end of the pencil, counting her/his steps. Shout stop when he/she reaches the end.

Fifth task. Work out the height of the tree. A step is about  60cm. You might need to check this with your friend, what is his /her step distance.
