In lab this week, we're studying ways we can influence human heart rate. One interesting concept in the mammalian dive reflex, a response that has evolved in many mammals including humans. Heart rate plummets in response to underwater conditions to conserve oxygen. We're using Vernier Lab Quests to document this.

There's a good article on NPR's website about the risk of Lyme Disease...caused by a bacterium spread by certain species of ticks. Our warm winter will probably result in an above-average number of ticks in our wooded areas this year so please educate yourselves. Above is a risk map. We're in a low-risk area but it's still best to check yourself after coming indoors.

8TH ANNUAL GREEN BUILDING SEMINAR SERIES
(5) Thursdays, February 9, 16 & 23 and March 1 & 8, 7:00-9:00pm
at First Unitarian Church of Ithaca Annex, 208 E. Buffalo St.(near Aurora), Ithaca NY

February 9: Earthships! A showing of the award-winning documentary, Garbage Warrior, will be followed by a discussion with one local couple who recently built an earthship and another who are working on one this year with Michael Reynolds (the leading earthship guru, featured in Garbage Warrior). For more about the film, visit: http://www.garbagewarrior.com/

February 16: Deep Energy Retrofits. What does it take to turn a typical home into a super-performer? Jon Harrod of Snug Planet and Ian Shapiro of Taitem Engineering will walk you through their process for making a home super energy-efficient and discuss the huge benefits that can result.

February 23: Rehabbing Old Windows. With a few simple repairs and improvements, you can make your old windows perform as well as new ones. Mark Pierce, Extension Associate with Cornell University's College of Human Ecology, is an expert in energy efficiency issues in residential buildings, and Shad Ryan is the Owner of On Balance Solutions, which specializes in vintage and historic sash rehabilitation. They will discuss the benefits of keeping your old windows and walk you through the process of fixing and tightening them up.

March 1: Affordable Green Building. Following up on last year's popular seminar, we've invited two local experts to discuss different strategies for keeping your green building projects affordable, including the decision-making process that goes into incorporating green building practices and materials that are healthy, safe, resource-efficient, and durable but that don't cost a premium. Scott Reynolds is the Director of Construction Services for Ithaca Neighborhood Housing Services, and Joe Laquatra is the Hazel E. Reed Human Ecology Extension Professor in Family Policy at Cornell University, whose teaching and research efforts focus on sustainable aspects of housing.

March 8: High-Efficiency Heating Systems. So, you've made your home as energy-efficient as possible and now your old boiler isn't just inefficient, it's oversized. There are a lot of options these days. We'll discuss high-efficiency biomass and fossil fuel-fired systems, mini-splits, geothermal, masonry heaters, and more, including how heat-recovery ventilation works as part of the system.

Admission: $8/seminar or $35/series. No need to preregister.

Introducing...Senior Projects

2011-12-15T19:31:00.001-05:00

Today I'm thrilled to announce the beginning of our work on Senior Projects. Pick a topic you are passionate about... it can stem from a problem right here at GCS or could be global in nature. It could relate to science but it doesn't have to. Use interviews, technology, fundraising, video, presentations, boycotts, campaigns, surveys, etc. to learn, educate others, and address the problem. Document your progress over the next two-three years and during your senior year, you will be given a venue to present or display your culminating project. You should also create a tab in your ePortfolio for this endeavor. Don't forget to use experts around you...GCS, SUNY Cortland, Cornell, Ithaca College, etc.

Some resources to get you started:

Insectapalooza: The good, the bad, and the bugly coming up!

Insects – from the good to the bad to the bugly – will be on display at Cornell University during the 8th annual Insectapalooza Insect Fair on Saturday, Oct. 29 from 9 a.m. to 3 p.m. at Comstock Hall on the Cornell University campus. The cost of entry is less than a cup of coffee: $1 per person.

Insectapalooza is an interactive, hands-on experience that features hundreds of live insects, spiders, and other fascinating arthropods. This year there are many new exhibits and popular favorites like the live Butterfly room, Arthropod Zoo, and Pollination room. Insectapalooza is fun and educational for children, teens, and adults of all ages.

The annual, one-day insect fair is hosted by the Department of Entomology at Cornell. "The Good, The Bad, and the Bugly" theme reflects the countless ways that insects interact with people and impact our lives — for better or for worse.

I have attached a poster for your use. We have plenty of parking for cars and buses.

This school year and next, Groton students will have to opportunity to do something truly unique. We are building an Earthship permaculture system in Freeville! This fall we'll be putting the finishing touches on the Earthship barn, which will be vital for livestock, storage, and rainwater collection. The barn could not have been completed without the help of Mr. Filzen, Mr. Wiech, Mr. Giroux, Mrs. Hume, and Ms. Bassette who stopped in periodically over the summer to help out and lend equipment.

Today we had a mini workshop to learn how to build with garbage. Here, seniors, Alex and Quinn work on making bottle bricks for a can wall. Bottles are cut 4" and duct taped together in various color schemes.

10th graders, Cali and Nick start work on the final wall of the Earthship barn loft. The nails and lath strips secure the wall to the wood structure. The barn boasts recycled plastic shingles, locally-cut hemlock boards, old reused windows, and incorporation of over 2,000 aluminum cans and discarded glass bottles.

2011-08-30T21:49:00.003-05:00

Welcome to the 2011-2012 school year. 11% of the 21st century is now over. That being said, how many of you feel you have a good grasp of 21st century skills like cloud computing, virtual collaboration, or currently maintain a website or blog other than Facebook? Do you check Twitter feeds or read a book from a Kindle? What was the last podcast you listened to? Would you feel comfortable if an employer needed you to use Photoshop, Microsoft Excel or Google Docs on a regular basis? Do you feel prepared to enter college and a workforce with other young people from Germany, Asia, and India? How has Groton done so far preparing you for the last 89%?

Last year was the toughest year to date for me, personally and professionally. After losing teachers like Syracuse, Giroux, Toyama, Varga, etc. - in most cases because the school and Board of Ed. cut them - I have had to reflect deeply about these losses to Groton and about this profession in general and how we need changes in US education. We need changes in public attitude towards education, changes in education law and unions, changes in school leadership and teachers, changes in school-day structure and changes to what politicians think you need to learn in school.

Every student in Groton should have learned last year that they can no longer take education and their teachers for granted. This was my favorite picture from last year in 7th grade... students staying after school in preparation of acting at a Board of Education meeting. It is now time to stand up and demand the changes mentioned above because NOTHING will change if you sit back and let the adults around you try to change things for you.

This year I invite you to "go rogue" with me. Lets change the school and world together and not worry about what others think of us along the way!

2011-06-28T21:14:00.001-05:00

Congratulations GCS class of 2011! This group was my first cohort at Groton. Here is a picture of some of them during a spring Adopt-a-Highway cleanup many years ago. I look forward to seeing them do wonderful things in their adult lives.

Friday marked the last day of the school year. I really enjoyed working with this year's 7th grade class...my last at Groton Middle School. The good news is that I will see them again in 10th grade and look forward to these students that have blossomed over the past year.

Have a good summer guys and remember to be good role models as 8th graders next year. Keep in touch!

2011-06-08T15:19:00.000-05:00

Tompkins Youth Rally for their Future

200 local students join Youth Power Summit on April 9 in Ithaca

On Saturday April 9, up to 200 young people from across Tompkins County
and Central New York will converge in Ithaca for the “Youth Power
Summit”, scheduled for 9:30 AM to 5 PM at the Holiday Inn. The summit
will educate, energize, and empower high school and college students for
a day of strengthening movements for clean energy, local food, and
social justice in their schools and communities.

“We are excited to bring together young leaders from all backgrounds
calling for bold action to build a clean energy and local food economy
that respects all communities.” said Megan Ludgate, Dryden High School
junior and member of the summit organizing team. “April 9 is about
empowering ourselves to lead this change.”

The summit is free and open to all, and will include lunch, workshops
for youth and educators, presentations, and action planning sessions.
Key organizers include students of the Lehman Alternative Community
School, New Roots, Ithaca High School, Dryden High School, Ithaca
College and Cornell University.

“Youth in Tompkins County are coming of age amid increasing crises,”
said Jordan Stark, Lehman Alternative Community School senior and member
of the organizing team. “When we look around, we see climate change
and threats to our water from gas drilling, a lack of jobs and
opportunity, and young people struggling to find meaning in our lives.
This summit will help us come together to create a better future in our
community.”

The summit features a panel of local young elected officials, including
Ithaca City Council members Svante Myrick and Eddie Rooker, Tompkins
County Legislator Nathan Shinagawa, Caroline Town Councilmember Dominic
Frongillo, and Binghamton City Councilmember Lea Webb. The elected
leaders will discuss their experiences in office and how young people
can engage in the political process.

“We are excited to announce an all-star panel of young elected
officials,” said Ariana Shapiro, Ithaca High School senior and member of
the organizing team. “These leaders are on the front lines of change
and will help inspire other young people to get involved.”

Youth will share updates on campaigns at their school and plan for
future efforts. Workshops on local food, social justice, political
activism, hydraulic fracturing, and energy efficiency are also planned.

“This summit is about coming together to build a better future for all,”
said Dominic Frongillo, Caroline Town Councilmember and Cooperative
Extension community energy educator. “We are saying ‘Let’s create
equity in our schools. Let’s measure progress not by the number of
people in jail, but by the number of people from our community who are
hired in good jobs upgrading our homes for energy efficiency. Let’s grow
our people as well as our food.’”

The all-day summit will begin with a “Generation Waking Up Experience,”
focusing on new ways young people are joining together for positive change.

“Both locally and nationally, young people are waking up and seeing an
opportunity to build a thriving, just, and sustainable future that
includes everybody,” said Doug Indrick, senior at Ithaca College and
member of the “GenUp” facilitator team. “The message on April 9 is
youth are building power to create our future.”

The summit is the weekend before 200 students from Tompkins County will
attend Power Shift 2011, a national youth summit April 15-18 in
Washington D.C. Over 10,000 young leaders will converge for the historic
summit, which will include the nation’s largest congressional lobby day.
According to the website, the Power Shift 2011 summit aims to “reclaim
our democracy from big corporations and push our nation to move beyond
dirty energy sources that are harming the health of people and the
planet.” Information on the national conference is online at
www.powershift2011.org.

“We are the leaders we’ve been waiting for,” said Vicky Morgan, Cornell
sophomore and member of KyotoNow! student group. “I have a sense of
urgency. We cannot wait another 5 years to address climate change and
social justice. I want us to look back and say, at this critical
moment, we rose to meet our challenges.”

This week we're covering the Plant Kingdom and it's amazing diversity...everything from the very simple mosses that rely on diffusion for water and must live near these water sources to the very advanced angiosperms that we're mostly familiar with. Today we dissected a lilly to see the male and female parts of a flower. The dissecting microscopes gave us a great look at the pollen-covered anthers.

Check this site for more information on flower parts.

Today we wrapped up the Tetrahymena labs. Thanks you Fern for all of your help prepping the labs. Here we are testing the effects of different spices and herbs on their behavior. We found that cinnamon and poppy seed were huge repellants and they were attracted to chopped onion and garbanzo beans.

Today we finished the Tetrahymena mating lab where we identified one unknown mating strain among the seven found in these protists. Here, Franky and Michael introduce the potential mates.

Yesterday we did our first Tetrahymena experiment by feeding them India Ink particles to observe food vacuole formation over a period of time. Today we analyzed the data and brainstormed other ways to test food vacuole formation.

Today we were introduced to the protist Teterahymena
, which we will be working with over the next week and a half on labs developed by Cornell University. They are approximately 100 microns long. The scanning electron micrograph above shows the ciliate in pursuit of an E. coli dinner.

Wyatt and Tristan show off their bacteria cultures. Today's conclusion: the dirtiest places were phones, drinking fountains, and of course, Mr. DeVoe's keyboard. The cleanest: inside of the toilets!

2011-01-13T12:00:00.000-05:00

Today we took potential bacterial samples from around the class and school. Above, the girls try to see how dirty my keyboard is! Lets hope the results turn out OK!

Lexi finishes up her sample with some Parafilm before putting it into the incubator.

Viva la revolucion!

In a democracy, people should feel safe to speak out if they do not agree with something. An informed student's voice is a powerful thing.

I ask you...

How would you change Groton so you learn better?

UPDATE: Meeting after school on Tuesday in Rm 302 if you are interested in sharing your ideas.

We've started bacteria and viruses in class. This unit involves an infectious disease project where you will write the dialog to a movie. If you wish, you may act out the scene in class or use the website http://www.xtranormal.com/ to create an animated movie. However, you must be 13 and have an email address to sign up.

I have to post something Mr. Syracuse forwarded to me. A class of 8-10 year olds did a study on bees and it got published in a major scientific journal! It's absolutely amazing. So, anyone up for trying to do the same with their Science Night project? If so, read the full paper and see how they formatted their findings. It's pretty amazing stuff....even if the teacher helped a little.

Here is a video about the students:

The current focus in Food, Land, and You is on the obesity epidemic and how to eat healthier. Today we prepared a healthy lunch of basil pesto, oven-roasted red peppers, and fresh mozzarella toasted on fresh bread. Dessert was a ripe pomegranate. Each serving cost around 50 cents and contained no processed foods.

Since Friday was my last day, I wanted to take some time to thank all of the students and Mr. DeVoe for such a great 7 weeks of student teaching. I learned so much and made some great friends along the way. I will truly miss Groton Middle School! I appreciate the goodbye cards, dances, and kind remarks, they all made me smile. GMS is a great place, and what truly makes it great are the remarkable teachers and students. Keep up the great work and I'll definitely be back to visit! I hope to stay in contact with all of you through my blog, www.hawaiiannene.blogspot.com. Have a great end to your 7th grade year!

Today we removed our eggs from the corn syrup and noted the changes from yesterday. What role did osmosis play in this transformation?

Jenna holds up her egg membrane which has lost most of its water content.

Today we removed our eggs from the vinegar and recorded the new data and observations. After measurements, we submerged the eggs in distilled water.

Jacob shows off his new membrane-bound egg.

2010-11-30T15:32:00.000-05:00

Today was day 1 of a 4 day osmosis lab. We are studying diffusion of liquids across an egg membrane. We entered initial mass and circumference data into a spreadsheet and tomorrow we will check our eggs to see what happened after spending 24hrs in vinegar. Here, Nikiah and Shania measure circumference.

We are finishing up the Herbs and Spices unit in Food, Land and You. Before the break we cooked up some eggs and other great foods using herbs and spices we learned about to add an extra zest to a usually boring egg!

2010-11-19T17:01:00.000-05:00

Today we looked at plant cells under the microscopes - onion cells to be specific. Iodine was the stain we used to highlight the nucleus and cell wall. Tuesday's test will cover all organelles and their functions.

Today was pond-water exploration day. Not the best time of year to look at pond-water but we made some great discoveries, nonetheless.

The best came 9th period when AUSTIN V. brought in a sample from home. Just from looking at it with my eyes, I could tell it was loaded with Volvox. Volvox is a colony of algae cells (sometimes up to 50,000 cells) that are just visable with the naked eye. This view is under 100x magnification.

Ancestors of Volvox transitioned from single cells to form multicellular colonies at least 200 million years ago, during the Triassic period. An estimate using DNA sequences from about 45 different species of Volvox and related species suggests that the transition from single cells to undifferentiated multicellular colonies took about 35 million years.

In the elementary school outside of Ms. King's class I noticed this cool poster on seed dispersal. Why would plants evolve mechanisms like this to move their seeds?

Here is the website that we explored a little in class on Friday about the "micro-artist." Check it out. It is a pretty awesome example of how science can be used in other subjects like art!

Today was our first "hands-on" day with the microscopes. We are in the process of familiarizing ourselves with the parts and functions of the scopes and how to create a wet-mount slide. We will have a quiz fairly soon on microscope safety and the functions of each part. Below is the virtual microscope we used in class:

Our trout came today 5th period. Here, Michael takes a closer look before we dumped them into the tank.

2010-10-20T16:57:00.000-05:00

Mercedes spent some time today getting the trout tank ready for tomorrow's egg delivery. We will be receiving about 100 Brown Trout eggs to raise until May when we release them back into the wild. Mercedes tested water pH, ammonia, nitrite, and nitrate.
