A school class at Colquitz River Park in Victoria, BC

Along the Cowichan River, surrounded by the smell of cottonwood resin, an elementary school student discovers that dragonfly larvae look like aliens. In a quiet wetland, a middle school teacher marvels as a guest expert shows his class how to fold cat-tails into duck shaped toys and send them downstream with wishes. In a municipal office, a bureaucrat considers a community proposal, initiated by an elementary school class, to create a new park.

Since 1994, the Colquitz Watershed Stewardship Education Project (CWSEP) has been bringing students, teachers, and the community together to experience educational turning points like those above. Headed by teacher Lenny Ross, the award winning project has successfully instilled an environmental ethic in students of all ages and their teachers by connecting them to the watersheds in which they live.

Hatfield Marine Science Center

The Southern Ocean surrounds Antarctica and serves as a conduit between the Atlantic, Pacific and Indian oceans. Yet because of severe climatic conditions, much of this ocean basin remains unexplored. Polar regions play key roles in the global environment and one goal of our project is to document linkages between changes to the Antarctic ice sheet and the volcano-tectonic seafloor processes in the region. To meet the challenge for continuous monitoring in this extreme environment, researchers from the Hatfield Marine Science Center utilized the Russian icebreaker Yuzhmorgeologiya to deploy an array of Autonomous Underwater Hydrophones (AUH). This new ocean-sensor technology uses cold-water capable, deep-ocean hydrophones to record sounds generated by moving ice sheets, undersea earthquakes and volcanoes; even vocalizations from large baleen whales. When the AUH array is recovered in 2006, sounds that it has captured will enable accurate monitoring of global climate change, as well as identifying previously unknown volcanically active regions on the polar seafloor.

Innovative tools allow a teacher to extend class activities on stream ecology and forest history

I have made an interesting observation about teaching recently.  Some of the best lessons are not necessarily the carefully planned and orchestrated units, but rather the ones that grew and took shape as the project progressed.  I have found that some of my best teaching has been when I didn’t know the exact outcome in advance and learned something new right along with my students. This has been my experience with environmental exploration into stream ecology and the “Leaf Pack” program. Read more

I review children’s books, and I read through plenty on science and nature. I can honestly say that I felt a wave of relief when I came upon Awesome Ocean Science! Investigating the Secrets of the Underwater World, a Williamson Kids Can! Book.

I recently took home a big stack of books on the environment, and I was disappointed, not to mention bored by most of them.  Perhaps appropriate as sources for school reports, I can’t imagine a child spontaneously picking one up for leisure reading. In fact, some of these books would test even an adult without bulletproof interest in the topic.  Well-written and visually appealing, Awesome Ocean Science! stood out in the crowd. Read more

What causes ocean currents? What impact do they have on Earth’s environment? How have they influenced human history?

This teaching guide for grades 5-8 provides 7 activities for students to explore the causes and impacts of ocean tides and gain an understanding of the influences of wind, temperature, salinity and density on ocean movement.

Students are given the opportunity to explore such real-world situations as the 1990 Nike shoe spill, the raft Kon Tiki, and other oceanic voyages in history.
