On May 10, 2010 ACER worked with St. Roch correspondents to facilitate the “Let’s Plant, Measure and Mulch” program at Humber Arboretum. This program offers teachers and environment clubs a unique chance to relate science to technology, society and the environment at our Outdoor Climate Change Laboratory located at the Humber Arboretum. The event was a great success and everyone went home having learned something. Thanks to all who attended and we hope you enjoyed your experience at the Arboretum.
