Mathematics on LC Team 9A is on full throttle! Algebra classes have studied linear functions and their graphs and equations this semester. Most recently we have been solving systems of equations in many different ways including on the graphing calculator. we have also used systems of equations in many applications. Geometry has been getting introduced to proofs along with their study of triangles. Crazy angle problems have been challenging. Coordinate proofs have also been very interesting. Both classes are ready for their unit assessment this week. Remember this: Mathematics is Logic, and Logic is the stepping stone into adulthood.

Goodbye, Invasive Species. Hello, Biodiversity!
Students are nearing the end of Unit 3 focused on biodiversity. We started the unit by learning about what biodiversity looks like and how to quantify it by calculating the diversity index. This was modeled through an activity called "Bird Island", which also helped to build our vocabulary with terms such as species, abundance, and endemic species. Students first calculated bird populations, graphed the population data, and then analyzed their data to use as evidence when discussing questions related to biodiversity.
Last week, we had beautiful weather to remove two invasive species right
in the backyard of our school. Students learned about how invasive species impact biodiversity and the environment, the different ways invasive species come into the United States and then several methods to remove them from the ecosystem. Ten classes of biology students walked out behind the softball fields to manually remove two local invasive species, Buckthorn and Bittersweet Vine. Clippers, root jacks and pure muscle ripped out the invaders and provided room and additional resources for other native species to continue to grow in the forest. Sixty compost bags of leaves, branches, vines and roots are evidence of the students' hard work and dedication to help with habitat restoration at our school.
The last piece to our biodiversity unit is presenting on how human actions such as deforestation, urbanization, pollution, and agriculture (just to name a few) affect our global biodiversity. Possibly even more importantly is how science, technology, government and non-profit organizations are developing solutions to reduce the impact humans have on our plant and animal species. I am looking forward to hearing the students' presentations in early December!

Editorial Cartoons
Ian Kirner's cartoon concerning the Pokemon Go craze |
Jenny She's cartoon providing political commentary |
Georgia Zimmerman's cartoon this year's Nobel Prizes |
Mari Lynn's cartoon concerning the demotion of Pluto |
Young Authors
Students in Mrs. Teal's Writing Through World Literature class have been reading, critiquing, discussing, and writing personal narratives as they investigate how storytelling helps us understand and respect other people's perspectives and identities. After writing their own mini memoirs, students were invited to enter their works for publication in Teen Ink Magazine, a national magazine, book series, and website whose sole purpose is publishing and sharing teen writing and art.
Memoirs written by Brett Almany, Evan Saroken, Jenny She, and Eli Rubin have been published on Teen Ink's website. In addition, Darby Krugel received an editor’s choice award, Sophie Henderson earned a front page feature, and Leen Rass earned a reader’s top pick recognition. Congratulations to these students!

What Makes a Healthy Ecosystem?
We just finished Unit 2 in Biology that focused on many aspects of ecology. During the last couple of weeks the students learned about the flow of energy through an ecosystem, how species interact to survive and how certain factors in the environment limit population growth. Visualizing how species interact through relationships like mutualism, parasitism and predation was especially fun using National Geographic video clips. You will have to ask your student to describe the parasitic relationship between the caterpillar and wasp larvae or how wolves are keystone species in Yellowstone National Park (see link below). Throughout this unit various graphs and data were analyzed, which is a transferable skill that I hope students can use throughout high school and beyond. The students also used their math skills to calculate different aspects of populations, including predicted populations and population density. Next week we are starting a new unit on biodiversity and how human activity impacts the variety and number of species throughout the world. This unit will end in December with student presentations that explore the threats to biodiversity as well as evaluating solutions to decrease humans' impact on biodiversity.
