    “Just like peas and carrots” the saying goes. Basic ecology is all about relationships and simply what goes together. Everywhere you look one plant or animal is relying on another organism, and the more you examine a single plant or animal the more you realize it is connected to another, and then another...The very definition of ecology is the study of relations of living things to each other and to their environment. Some educators and students may think of the savannas of Africa or predators and prey in the Arctic when “ecology” comes to mind, but it can be studied in a scene as small as a raised flowerbed in a schoolyard and most certainly during a field experience to an actual prairie, Ozark woodland or glade.

    Ecologists refer to these relationships as symbiotic. A symbiotic relationship is where two species live together in an intimate association and one or both species benefit from the relationship. Symbiotic does not always mean a benefit for each species. Where they both benefit we call that mutualism. The second type of symbiotic relationship is where one living organism clearly benefits, but the other seems to experience no

    positive or negative effect. We call these types commensal or commensalism. The third is parasitism, where one organism has a benefit and the other is disadvantaged in some way.

    An established plot of selected milkweed species and other prairie forbs and grasses, as discussed in part one in the STOM newsletter, will lend itself to an array of studies and be geared for all ages or grade levels. Upper elementary students to high school students often examine such relationships, which go far beyond one species providing food for another. Relationships dealing with transport of seed, protection from sun or wind, watching for mutual predators, and providing suitable conditions so another may live or raise young are just a few examples.

    See if you can distinguish these three different symbiotic relationships that could be observed from a STOM Milkweed Connection Learning Station in a schoolyard.

    Commensalism, mutualism, or parasitism?

    1) A hackberry butterfly lapping the salty sweat on the forearm of an observing student.

    2) A tachinid fly laying eggs on a variety of caterpillar species.

    3) An American goldfinch dropping the milkweed seed, but

    using the fluff from the seed to line its nest.

    4) A hover fly (bee mimic) in the center of a yellow crownbeard flower. The flower is in a sense bartering nectar for pollen transport.

    Discussions about or observations of symbiotic relationships can truly engage students who are learning about ecology. Studying symbiotic relationships in turn can lead to more life science studies, collection of mathematical data, creative writing, and application of the fine arts.

    Dear Middle School Science Teacher:

    My name is Barbara Nagle. I am a curriculum and assessment developer at the Lawrence Hall of Science at the University of California, Berkeley. I am planning to conduct a research study, which I invite you to take part in.


    We are doing this study to develop assessments to monitor students’ progress towards understanding the Next Generation Science Standards (NGSS). These assessments are intended for teachers to use at the end of a science unit and will be provided as open educational resources for broad use in a variety of educational settings.


    If you would like to take part in our study, you will be asked to assist with the research activities that will take place in your science classroom, where students will respond to drafts of the assessment items. This will require permission from your principal and/or district. Your participation in our study potentially involves engaging in two activities. The first activity is providing our research team with your written feedback about the assessment items used for testing in your classroom. Your written feedback will help us improve the assessment items for use in classroom practice. After completing the written feedback about the assessment items used for testing in your classroom, you may be invited to take part in a focus group activity. This activity is optional and your participation may depend on your availability. This focus group will meet for up to three 8-hour full-day sessions at the Lawrence Hall of Science in Berkeley, California or at a site convenient to your school district. You and the other group members will discuss the drafts of the assessment items and scoring rubrics, examine student work samples, and work with project staff to revise the items and scoring guides.


    There will be no direct benefit to you from participating in this study other than an opportunity to see some assessment items developed for NGSS. However, it is hoped that the information gained from the study will allow us to generate a set of high-quality assessment tools that will allow teachers and districts to monitor their students’ progress towards mastery of the Next Generation Science Standards. These tools will be available to you and others at the end of the project.

    Who can participate?

    To participate, you must be currently teaching the NGSS in your middle school science classroom at a public or private school. Additionally, your principal or district must agree that we can conduct research in your classroom.

    If you are interested in participating, please contact Sara Kolar at (510) 642-8719 or via email at srkolar@berkeley.edu.

    Rosie the Ribeter: The Celebrated Jumping Frog of Calaveras County

    Who holds the world record triple jump record – for bullfrogs?

    Rosie, the Ribeter.

    She set the record in May 1986 at 21 feet 5 ¾ inches.

    Her record has stood for over 30 years.

    This is her story.

    It all started with Mark Twain and his famous story, “The Celebrated Jumping Frog of Calaveras County.” After it was published, the 39th Agricultural District in Calaveras County, California started the Jumping Frog Jubilee, which has run since 1928.

    Over the years, the frogs have jumped farther.

    Why? Scientists say it’s because of the frog jockeys, the men and women who catch and jump the frogs.

    Read this extraordinary story of a partnership between a man and a frog.
