Have you ever looked up at a tree and wondered how tall it is? I’ve got a fun way you can find out without having to climb to the top with a tape measure!
How can you measure how tall a tree is?
We have an easy way to find out!
Why does it work?
This method of measuring the height of a tree is only an estimate but uses trigonometry. If you look at the top of a tree at a 45-degree angle, then the height of the tree (h) is the same as the distance that you are from the tree.

Did you know you can make a weather station using pinecones?
Or how about collecting pinecones and leaves to make estimating jars?
Do you know the three different ways of working out how old a tree is?
A homemade wormery is always a fun outdoor activity, too and great for observing over a period of time.
We LOVE these cardboard nature hearts from learning through play!
