We spent a great evening at Millennial Tech Middle School’s Winter Science Festival in the Chollas View neighborhood of San Diego. San Diego Coastkeeper Core volunteer Caitlin, San Diego Coastkeeper’s education coordinator Nia, and I were on-hand to provide brief 25-minute educational sessions on marine debris.
The ‘Marine Sea Animal Entanglement Exercise’ was shared with students and their parents. Eliciting answers to questions regarding how marine debris such as plastic bags, cigarette butts, oil, and other items end up in the ocean and have their effect on sea life from students was fun and students always provided many examples of how this happens. Students know remarkably well the effects of pollution on their environment and how it can affect marine life as they explain it to everyone participating in the exercise.
The exercise has students (and parents) pinch their fingers together like a dolphin beak or rostrum, pick up beans scattered on their table (representing fish), and placing them in a container for a 30 second time span. Each student then counts how many fish she or he caught and scores are tallied. Then a rubber band (representing a plastic bag entangled on the beak) is placed over the fingers and students again try to catch fish for 30 seconds. Scores are tallied and students can see the effects that this has on animals trying to survive in the wild.
One of the more interesting discoveries by most parents doing this exercise is that San Diego sewage and stormwater drainage are really two separate entities, that is, stormwater does drain directly into the ocean taking all the trash that accumulates on streets and watersheds with it directly. Educating parents and their young students in outreach activities like this is another step to moving towards San Diego Coastkeeper’s goal of having swimmable, fishable and drinkable water for everyone.
Millennial Tech Middle School is a magnet school with a focus on science, technology, engineering and mathematics (STEM).
