As a part of our project we decided to make a flower tree. There are many activities to make blossom but my idea was to give children a chance to see how it happened. So, when project started once I brought in classroom a few branches of different threes a nd ask children if they can guess what is that? They answerd sticks, branches, nothing else. We put those branches in the jar with water and observed the branches for more then 10 days. That was experiment which help children to understed where leaves come from in the spring. They were very surprised that the flowers were appeared first on the branches. But tu have first flowers you will need branches of apple, cherry tree. The best is genista, which has a beautiful yellow flowers.
