| Professor Pricklethorn |
Learn to see trees through the Professor’s eyes and his green-coloured lenses and you will see the environment around you in a very different way. Trees are not just outdoor furniture for us to use. If we learn to respect and care for trees then they can help us and the global environment in countless ways. Professor Pricklethorn wants to help teachers, parents, and children learn how to make the connection between science and everyday life by learning about the many good things that trees do for us every single day. |
