So far this year, EHSC COEC has reached over 500 students through ten different OSU Precollege Program events.

Examples of Precollege Programs we have been involved with include:

The students range in age from 2nd – 12th grade and come from diverse areas of Oregon such as Eugene, Newport, Siletz, Salem, Ontario, and Corvallis.  Diana Rohlman, COEC Program Coordinator took the lead with help at some events from Erin Madeen and other graduate students affiliated with the Environmental Health Sciences Center (EHSC).  On the EHSC web page, there is a resource page for K-12 Educators, which includes curriculum, eNewsletter, workshops, and funding resources.

In addition, Sinnhuber Aquatic Research Lab hosted a 5th grade class on May 12th. See the story on the SRP blog: 5th Graders Experience All Aspects of Zebrafish Research. We also engage families at Davinci Days and Pet Days.

Using Integrated Problem-based Curriculum

Lisa Troy, an 8th grade science teacher at The Sage School in Foxboro, Massachusetts chose the NIEHS-funded Hydroville Curriculum as a way to give her students a real-world problem to solve, teach them collaboration and teamwork skills, and expand their understanding of “doing” science. She was also very interested in environmental issues and once worked as an environmental consultant on EPA’s Superfund/RCRA Hotline.

In the Hydroville Pesticide Scenario, students work in teams to examine and clean-up a large accidental spill of metam sodium near a river. In this scenario students take on roles of an environmental chemist, environmental toxicologist, soil scientist, and mechanical engineer. It creates a valuable experience to learn about these careers and how they work together to solve problems.

I was very pleased with how involved my students were in their roles. Since they were responsible for their own area of expertise, they took ownership of the skills and information that they learned. The students also enjoyed fitting their solution into the constraints of a budget, as well as considering stakeholders’ varying viewpoints. Their parents attended the presentations and took on roles as stakeholders when asking questions. Their presence increased the feeling of a real town meeting, and it was fun to see the students dressed up! ~ Lisa Troy

Communicating with a Scientist

The students were learning about toxicity, LD50, and NOEL (No Observable Effect Level) through a seed germination lab. Lisa Troy had read about Dr. Tanguay in the recent YALEe360 article, and she shared his research with the students. The students were very excited to speak to a “real” scientist who is engaged in meaningful work and making a difference. A highlight for the students was when they Skyped with Dr. Robert Tanguay.

Students were especially interested to learn how zebrafish are being used as models of human response to chemicals in research all over the world. They shared a long list of questions with Dr. Tanguay in preparation for the Skype event.

The students were intrigued by the idea that, through research such as Dr. Tanguay’s, chemical manufacturers will know much more about the effects of individual chemicals and the possible synergistic effects of mixing chemicals. They were reassured to learn of the human treatment of the fish, as well.

Not only was Dr. Tanguay’s interview incredibly valuable, it taught my students an important lesson about research: that you can contact scientists and experts in their fields and obtain information directly from the source. Science is not just in a textbook. ~Lisa Troy

To increase career connections, Lisa Troy asked the parents, teachers, and administrators to identify any skills that were important to them in their work or life experience from a list she generated of all the skills the students learned or used during the course of Hydroville. They checked nearly all of the skills!

As the year progresses and we study other topics, I will continue to reinforce the concepts and skills the students acquired during Hydroville and know that they will be well prepared for the future. ~Lisa Troy
