    Hello students, parents, families, community I truly hope that this message finds you well.  As we all face this unprecedented threat in our lifetimes of the novel Coronavirus pandemic we are instructed to shelter-in-place and practice "social distancing" when out in order to reduce risk of exposure to ourselves and our loved ones.  I encourage you to check news websites daily to monitor the situation i.e. abc7newsSF, Fox2Oakland, CNN, BBC, etc.

    The school district faculty and staff will make a reasonable effort to maintain some degree of education via Home Learning Plan.  Likely within the next day or so the school/district will be sharing lessons created by teachers with parents & students.  The assigned textbook is all that is necessary to do the assignments I have crafted, though access to the internet may help as well.  I encourage all students to do as much of the assigned work as possible at a pace that is comfortable for you, though at present the work is optional learning and enrichment.

    FYI in Environmental Science we had just started a Vermicomposting Project in class.  The Red Worms are fairly hearty and can survive tough times for a while.  Likely they will lay cocoons and there will be lots of baby worms when we return!  At worst, if our return to school gets postponed, the worms will donate their organic material to the compost itself ... the cycle of life continues.

  • What is the single most importatnt term or concept in Environmental Science?

    Sustainability. Sustainability has many similar but different meanings across different fields.  Basically it refers to humans using resources modestly so that the same resources are available for future generations.  It refers to humans living within their means, sonsuming resources at a rate below the sustainable yeield.

  • What is environmental science?

    Posted by:

    Environmental science is the study of how humans impact the envirnment.  It focuses on how humans use resources and alter the environment in the atmosphere, biosphere, geophere, and the hydrosphere. A major goal of the course is for students to learn how to identify and solve environmental problems.  It is a science course and is therefore about the science of phenomena related to the environment.
