Environmental Education (71)
Project SWELL well equipped to educate future generations on water issues facing San Diego and possible solutions.Written by Briseida Catano
Teachers have a great impact on the attitudes students have towards their class subjects and subsequently have the opportunity to cultivate an appreciation for San Diego Waterways. With the assistance of Think Blue and San Diego Coastkeeper’s Project SWELL curriculum, it has never been easier to instill a sense of environmental responsibility and awareness in San Diego youth.
The environmental education made accessible by Project SWELL, online and through classroom presentations to all San Diego Unified School District teachers, enhances current science curricula to better address pressing environmental issues related to local waterways. The Project SWELL lesson plans help teachers meet new Common Core and Next Generation Science Standards as well as raise awareness of issues that impact the San Diego environment and actions that students can take to improve and sustain it.
For the first time ever, due to the generous donations from Stiefel/Behner Charitable Fund, Project SWELL offers a choice of classroom demonstrations. These demonstrations give students access to hands-on experiments and models that promote critical thinking in determining solutions for pollution problems in San Diego. Classroom visits also allow the teachers to learn the SWELL material in order to continue implementing in classrooms with the SWELL kit and PowerPoint presentations given to the teachers. The classroom visits consist of various lesson topics and are designed with grade levels in mind.
There are various subjects, each tailored to specific class levels. The topics include lessons about identifying a marine animals’ habitat, storm drain pollution, what types of pollution are found in San Diego waterways and San Diego watersheds, water sources, and conservation. Not only do these lessons teach students about the issues San Diego faces, but the curriculum also incorporates material on how students can personally contribute to alleviating the issue.
Judging by the pre-assessments and post assessment student results given at a variety of San Diego Unified District schools from September 2014 to December 2014, it is evident that Project SWELL lesson plans enhance students' understanding of the connection between their actions and the natural environment.
Pre-assessments are given prior to the lesson plan and assess the knowledge on the presentation topics that students have preceding the lesson. The results demonstrate that many San Diego youth have a basic understanding on how their actions may affect the local waterways, as well as possible ways they can personally improve it. The post assessments indicate that Project SWELL deepens the students’ understanding about San Diego water supply, water conservation, and pollution problems.
The curriculum supplied by Project SWELL also helps teachers build their own environmental knowledge and teaching skills. We hope the skills and knowledge acquired from the curriculum will be a lifelong lesson for our students and teachers. We are confident that the Project SWELL lessons will motivate these individuals to inspire others to care about our most precious resource, water.
Wetlands are the superheroes of ecosystems. They may look like patches of mud and grass, but they're saving San Diego one tidal flow at a time.
In addition, they help regulate climate, store surface water, control pollution, absorb fertilizers, protect shorelines, maintain natural communities of plants and animals, serve as critical nursery areas, and provide opportunities for education and recreation.
Every December, January and February, in particular, they hold back some of the ocean's toughest tides. It's during these months that we have some of the highest tides of the year, AKA king tides. The average king tide is 5 – 8 inches higher than the average high tide. That might not seem like a lot until you see the Ocean Beach Pier get completely swamped by massive waves. But king tides also affect our coastline infrastructure, and it's our wetlands that soak king tides like a sponge. In fact, without the wetlands, San Diego's infrastructure would be more at risk during every king tide.
Wetlands save the day year after year.
But here's the problem: 90% of California's wetlands have been lost to development. And king tides are just a taste of future high tides. By 2050, rising sea levels are predicted to make everyday ocean water levels 12-18 inches higher than today's tides. That's an everyday tide that's more than double the height of our highest tides. And we're continuing to develop the wetlands, making our coastline less and less resilient to the impending sea level rise.
The California Climate Change Center predicts nearly 140 schools, 34 police and fire stations and 350,000 miles of road are at risk in California from rising sea levels and development of wetlands. It estimates that nearly $100 billion (in year 2000 dollars) worth of property is at risk of flooding from a 100-year event.
But don't take my written word for it.
Watch this time-lapse video showing the extreme high and low tides during king tides at Kendall-Frost Mission Bay Marsh at Campland on the Bay. I think it'll amaze you with how much water our wetlands absorb and also help you visualize why we must protect our remaining wetlands in San Diego.

Without question, my favorite task as part of the education team at San Diego Coastkeeper is teaching lessons for ProjectSWELL. Project SWELL (Stewardship: Water Education for Lifelong Leadership), a school-based science curriculum, teaches K-6 students about the importance of the San Diego region's waterways. Usually, Project SWELL offers free SWELL kits, curriculum and professional trainings for educators. But this year, the Stiefel Behner Charitable Fund has made it possible to give one hands-on lesson at every school in the San Diego Unified School District.
I go on solo missions to second grade classrooms with the goal of educating and inspiring our future leaders to care about water quality. In class, we create a model that shows how water carries sediment down an incline. After experimenting with water and earth materials, we add pollution. We put plastic, paper and aluminum on the slope and watch rain move the pollution downstream and straight into the ocean.
When I walk around with green and red food coloring to simulate pet waste and car oil, there is always an awesome simultaneous “ewwww!” I’m excited to watch the class engaged with water, pollution and solutions. The kids are stoked, the lesson is important, and the teachers are all helpful and enthusiastic.
Hearing children’s solutions to pollution is refreshing and exciting. A second grader from Miramar Ranch Elementary had the best solution I’ve heard so far. “I would vacuum the world!” How awesome is that?

As this historic drought continues, it’s easy to see how dependent we are on water. Allowing students at a young age to explore the water in their communities creates a better understanding of how to preserve and protect this resource while gaining valuable science skills.
That’s why in 2003, we partnered with San Diego Unified School District, and the City of San Diego’s Think Blue Outreach program to create Project SWELL (Stewardship: Water Education for Lifelong Leadership). In Project SWELL, the impacts of humans on water are explored through a well-balanced, comprehensive, and hands-on water quality and pollution prevention course of study. Project SWELL helps teachers empower students to understand and improve the condition of San Diego waterways.
Project SWELL is a state standards-based science curriculum that teaches children about the importance of the region's waterways by providing teachers with training about the scientific content, information on how to conduct scientific investigations and in-class support including materials, in class teacher trainings and lesson plans.
Through this partnership, San Diego Coastkeeper has created a hands-on program that offers training for teachers, makes it easy to engage students and meets new standards. Each Project SWELL unit of study (grades K, 1, 2, 4, 5, and 6) consists of 5 or 6 age appropriate, standards-based lessons that build student understanding of San Diego's aquatic environments and emphasize the actions that students can take to improve them.

Bio means life. Bioassesment means the study of life and living organisms--and we're full force with our bioassessment program in San Diego County. Bioassesment helps us understand the health of a lake, river, stream or ocean by looking at the organisms that survive there. Scientists have used many different organisms to test water quality; including, mussels, fish, and our favorite, insects.
Insects represent the majority of living creatures. In fact, there are more than a million species of insects. And they are found in many different places because they can survive in a wide diversity of habitats. Insects have special body parts that help them to survive. They all have a segmented body including head, thorax and abdomen. Some can fly, some can swim, and some can fit between very small crevices. These are just some examples of the eccentricities that help these clever creatures survive. Some of them eat live plants and animals, while others prefer their food dead. Some like to decorate themselves to blend in or have an extra "cover" for protection.
Why are there so many insects? What can their presence or absence tell us about the health of a stream? These are questions that can be answered when we pay attention to these incredible creatures.
Why do we study the insects in our streams, creeks and rivers?
Some of the insects can live only in very high water quality, while others can live in fair or poor water quality. This means, the insects that you find tell you if the waters are fair, poor or high water quality.
How do we know if the presence of certain insects indicates good water quality? The insects are classified by their tolerance to certain water conditions. Insects with a low tolerance (0-3) are considered to be very sensitive to decreased water quality.
Insects with a high tolerance (6-10) are considered insensitive to decreased water quality. So if you can find bugs with low tolerance in your streams that's very good news!
Who are the usual suspects of fair or poor quality?
- Syrphidae “Hoverflies” - 10
Who are the bugs that like high water quality?
- Chloroperlidae "Stoneflies" - 0-1
- Leuctridae "rolled-winged stoneflies" - 0
- Glossosomatidae "caddisflies" - 0-2
- Odontoceridae "Mortarjoint casemakers" - 0
What is the educational value of bioassessments?
Students can use several field guides to identify the insects and other creatures in their waters and relate their presence to water quality. Studies can range from basic identification to taxonomy, to collecting and identifying bugs. All of these activities are fairly easy and will teach students to use a key.
Students can examine the insect's mouth with a magnifying glass and infer to which functional feeding group the insect belongs. The students can then explore where the insect exists in the food web and what it needs to survive. For example, a shredder needs leaf material to fall into the stream and a grazer needs algae. Here is a helpful resource on functional feeding groups.
Zonation (Where does it live?)
Use location to answer questions about water quality. For example, where in the stream do you find certain species and is this related to certain water conditions (low oxygen, low pH, high temperature...)? This could work for both project based-learning and science fair projects.
English Language Arts and Arts & Crafts
Students can create their own bugs and tell their stories. What are the special body parts or behaviour "adaptations" that help them survive?

Plastic, though it was seen as a great technological advancement, has shown the world and the environment it’s dark side. Plastic, which has been used in just about every field, from medicine, to toys, has taken a huge toll on our environment. It washes up on beaches, is ingested by animals, and disrupts ecosystems. But that isn't all. Plastic has a bigger environmental impact than most think. We use oil to produce all the plastic that is used around the world making it so we are manufacturing our own demise
Heavy metal contamination can come from a variety of sources: the paint on boats, zinc in your tires, etc. Heavy metals contaminate the water and settle along the ocean floor where bottom feeders tend to feed. Though only small amounts of metal is consumed, when larger fish that are higher up in the food chain eat the bottom feeders, a higher concentration of the toxin is then present in their body. This is chain reaction is called biomagnification. Since humans are the top on the food chain, humans are also affected by biomagnification, making it a subtle yet dangerous problem.
Sewage is a large environmental problem but not for the reasons that most people think. A big reason why sewage is a problem is because of the excess hormones released in human waste. Only a small percentage of medication is absorbed into the body while the rest is expelled and finds its way to the ocean in sewage. Although wastewater treatment plants are able to remove around half of the hormones, there are still many steps that we need to take to remove the problem completely.
Cigarettes are not only harmful to humans, but to our environment as well. Often times, cigarette butts are improperly disposed of and washed into our oceans when it rains. Cigarettes are highly toxic to marine life, even in the smallest of doses. Ingesting or even being in cigarette contaminated water can kill marine animals, making this a serious problem that needs to be addressed.
What are the sources of pollution?
To understand the problem with plastic pollution, a group of students researched the common sources and effects of plastic pollution. As a result of their research, they found that 90 percent of the ocean’s trash is actually plastic. Research shows that 80 percent of the marine debris, including plastics, comes from land while 20 percent comes from boats. The most common sources of this pollution are disposable plastics like bags and bottles, and fishing gear that come from ships.
What are the effects?
The students discovered that the problem with plastic pollution is that the plastics last forever-this means the plastic continues to pollute the environment at every stage of its existence. Because of this, the ecosystem of the ocean, animals, and people are affected negatively. Animals can accidentally ingest or get entangled in plastics, leading to fatal results, while the marine debris in the ocean can harm the aquatic vegetation or suffocate coral.
How can it be fixed?
After finding out how plastic pollution can have negative impacts on the environment, the students moved on to figuring out how people today could fix the problem:
1. Find alternative to plastics, like reusable bags and water bottles
2. Throw away or recycle plastics and trash properly rather than litter
4. Support single-use plastic bag bans
What has been done so far?
Beach cleanup data from Coastkeeper beach cleanups suggests that a lot of the trash that was picked up was plastic. Because plastic is non-biodegradable, it will only keep breaking down into microscopic pieces in the ocean, making it much harder to actually clean up all of the plastic in the ocean. Also, the borken down plastic begin to resemble plankton, a common food source for marine life. So by completing these beach cleanups every year, more of the plastic that ends up on the beach can be picked up before it ends up in the ocean to break down and further pollute the environment.
