Our Teacher


Life Science Grade 7

7th Grade begins the year by learning about something big: whales. This is our springboard into the units for the rest of the year: even the largest whale is made of tiny cells; cells of multicellular organisms are specialized; whales and all other living things pass on their traits through heredity, genetics and DNA; whales belong to the animal kingdom and the less familiar kingdoms contain fascinating organisms; diseases and parasites can and do attack whales and all living things; whales became whales through an extremely interesting process of evolution; the ecosystem of most whale species is the ocean, other ecosystems contain other life forms; we can compare whale anatomy to our own.

Human Ecology Science Grade 8

8th Grade spends their year investigating how humans fit into, and affect, Earth's natural systems. We learn where our water comes from, how it is cleaned before and after we use it, and how our activities affect river and ocean health. We investigate the sources of our energy, how electricity is generated, and the effects of obtaining the raw materials, the electricity generation, and disposing of the wastes. We look up close at our food production systems: how our food is grown (by both organic and industrial systems), and the effects of food production on soil and water systems. We finish our year by examining the impact of our consumer choices on workers and environments around the globe.
