HMST Grade 9 Science students had the opportunity to to conduct hands-on exploration of two different kinds of ecosystems, Aquatic and Terrestrial at the Humber Arboretum, Centre for Urban Ecology. In the aquatic ecosystem investigation, students analyse the water in the pond, recording such aspects as pH, oxygen, conductivity, phosphorus and temperature. In the terrestrial ecosystem investigation, students perform a soil analysis, as well as assess the diversity and sustainability of the plants in the forest.
