During the course of the day we learnt even more about plant evolution.  First came the algae, then the moss, next were the ferns followed by conifers and finally flowering plants – a process of development that took over 500 million years. We also went on a tree-spotting walk and by the end of the morning, we were able to tell the difference between an oak, a plane tree and a cedar tree. All of the children also really enjoyed the opportunity to spend some time with our friends in the beautiful surroundings of the Royal Botanic Gardens.  On Monday we had even more fun with our science back at school when we learnt about the kingdoms of life in the Science Dome.  We learnt some amazing facts - did you know that a protist is only 0.0008mm in length
