This week we've been doing a diffusion/osmosis lab involving chicken eggs. Day one our eggs spent 24 hrs in vinegar, which dissolved the calcium carbonate shell. After spending another 24 hrs in distilled water the water diffused through the egg's membrane (osmosis), making the egg a little more plump. Today we removed the water and added a coating of thick corn syrup to the plump eggs. What do you think will happen by tomorrow morning??

Today we began constructing cell models using candy and household
items. Here, Tristin pastes down her nucleus.

Erin Marteal was in today to show us a brief overview of plant propagation, which is a way to reproduce plants asexually. She brought in a cool variety of plants and we actually got to practice rooting new plants.
Step one: Sarah loads up on the root-starting soil.
Step two: Select yor favorite varieties.
Step three: Sam shows off his new plant. Kodie C. even did a cool experiement where he used a root-growing hormone powder for the plants in one cup and the other cup he rooted normally (the control). We'll see how that works in a couple weeks.

Thank you Erin!

Today we did the famous onion cell lab where we looked at a one-cell thick onion film. This showed us very nice plant cells with the box-like cell wall and a clear nucleus in the middle. We also looked at elodea to give us a good look at chloroplasts. Earlier in the week we studied each cell organelle individually in groups and related them to real-world items. Nice job everyone and great idea Mr. Meade.

CELLS!

We are made of trillions of living building blocks called cells. We are currently studying them and the functions of the tiny organelles inside of them. Here are a couple great sites I found to help you memorize their functions.

Today, Sarah Cudney, a Cornell Sophomore came in to talk about
mammalian anatomy and locomotion. She did a great job and was nice
enough to haul in several skulls from Ithaca. If you enjoyed this talk
you may want to start thinking about going to college for wildlife
biology or veterinarian sciences.

The week after Thanksgiving signals the beginning of Project Feederwatch. Students will be able to sign up for Rec. birdwatching. We will be observing our school feeder and submitting our findings to the Cornell Lab of Ornithology's website. Last night I purchased a bunch of bird seed from Ms. Rae's bird shop in Lansing (http:/www.raesroost.com). Thank you also to Taylor P. and his family for donating seed as well. Monday we will begin learning several of the species of birds we will be seeing.

This thursday after school at 3pm my high school environmental science club will be watching and discussing the documentary, Food, Inc. I wanted to extend the invite to the 7th graders and parents as well. This spring will mark the 3rd (and best so far) year for our school's organic garden and this film will highlight the benefits of that effort. As a warmup, check out this student-run garden at Yale university...pretty sharp. If you would like to help out with our own garden, more information will be available this winter.

It was a fishy today for Mr. DeVoe's class. A Student from Cornell, James Costaras, came to talk about what the fish around here look like and what allows them to function. We got the opportunity to hear some big fish stories in class... Feel free to post your fishing stories in the comments below! A special thanks to Cornell and Mr. Costaras for joining us today.

Scanning Electron Microscope Presentation

video
Video From Today....Sorry about the camerawork.





Today we had the privilege of having Daron Westley, an electron microscopy specialist from Cornell come to our class with a PORTABLE SCANNING ELECTRON MICROSCOPE!!! The pictures seen throughout the day were truly amazing. They range from Mr. Meade's toe skin, to Courtney's hair to a freshly killed fly directly off the classroom window.




03 November 2009


A special thanks to Miss. Miller, a student from Cornell that came to speak on fireflies! The next time we look up into the night sky to see the glow of a firfly we will be able to see the beauty behind the biology. Look forward to Friday when we will be having a portable electron microscope brought into class!

Thursday night at 7pm I will be doing a presentation on The Appalachian Trail in my room. All interested individuals are welcome. It will be roughly 40 minutes with a question and answer session following. Hope to see you there...bring a friend.

02 November 2009

Today we welcomed our newest members into the classroom...about 100 newly-hatched Brown Trout (Salmo trutta) alevins. These guys came from a fish hatchery in Bath, NY and will grow and develop in our tank until we let them go in Owasco Inlet in April or May. It should be a great experience. Several schools in Tompkins County take part but we're going to keep our tank temperature slightly lower than the others to see if that affects their metabolism and growth.

Great job on the quiz on friday, the following students had perfect scores on their quizes! Timothy B, Tristen B, Mackenzie C, Anneleise H, Otis J, Courtney J, Chris H, Sam G, Ryan B, Allyson B, Alexis S, Drew B, and Camille H. Keep up the good work!

In this coming week we will be learning about how to use the microscope, along with having a vistor come in with a portable electron microscope and another speaker on fireflies!
On friday you got to hear a little bit about my experience with Honey bees. Here are some of the pictures shown in class just in case you wanted a second look. Over the next few weeks I will be showing you more of my amazing biology experiences.

Guest Speaker

Over the next couple weeks we will have several Cornell students in to
present a variety of topics. Today, Rick Cicciarelli was here to give
us a great lesson on honey bees. He even brought in a sample colony
for us to see. Very cool!

28 October 2009

I occasionally read a great blog by a guy out of Cornell. He usually posts about birds and salamanders but this cool photo caught my eye. Can anyone hypothesize what happened to this beetle? Many times in science, we're not around to observe what took place but can look at the evidence and test our best guesses through a variety of ways. Any guesses about this one?

Quiz Friday on microscope parts and safety! Here are a couple things from the interweb that I've gathered to help you study for the quiz. Remember, the quiz is on microscope parts and their functions and also safety. Here are a couple good sites:

Labeled Microscope

Quiz Yourself

Lots of information about what we covered this week.

27 October 2009


Today we rotated among 4 stations all dealing with microscopes. Here, Mr. Rhoads and Mr. Meade work on preparing wet-mounts and focusing with the microscope. We learned that a letter "e" appears upside down and backwards because of the lenses and mirrors within the bodytube. Friday we have a quiz on microscope parts and safety. Make sure you study!

26 October 2009

Greetings from your new student teacher!! I am very excited to get started with microscopes this week. I already know nearly all of your names, and look forward to getting to know and Mr. DeVoe. As you can see by my picture I have been to far corners of the world to study Biology and hope to share some experiences with you all. See you in class!

23 October 2009

The following students earned perfect scores on their taxonomy quiz: Annelise H., Tristen B., Mackenzie C., and Sam G. Way to go! We will go over these on Monday. Next week we welcome Mr. Meade as our student teacher who will be joining us until the end of December. Please make him feel welcome at Groton.
Yesterday Viola's Helping Hands helped out with the school garden. We ripped out all of the weeds and leftovers from this year's crops. Thanks again to 7th graders SAM N., ALEXIS S., KEIGHTLY M., CHAD D., and ANNA L. for being part of this along with several 6th and 8th graders. Here are a few photos:



After I roto-tilled everything up, we planted a couple rows of garlic that will pop up in the spring.

20 October 2009



Thursday after school I will be helping Viola and the middle school helping hands clean out the veggie garden for the year. We'll be pulling out the remains of this year's crop, adding compost, and roto-tilling everything up. If you'd like to help out stop by room 302 after school or join us at the garden across the street from the school.

The issue of drilling for natural gas is a hot topic here in Central New York. The "pros" of this issue include getting fuel from local sources instead of the middle east but the "cons" include major threats to our groundwater supplies. More info can be read here and here. If this is a topic you're interested in you can use the letter below and copy/paste it to Pete Grannis at petegrannis@gw.dec.state.ny.us or pop it in the mail to the address indicated.

Re: Draft Supplemental Generic Environmental Impact Statement
Gas Drilling in the Marcellus Shale and other like Formations


Dear Governor Paterson and Commissioner Grannis:

As a sportsman and conservationist, I am concerned about Hydraulic Fracturing and Natural Gas Development in New York State; and the potential negative impacts to water quality and supply. To this end, I write to you today requesting a minimum 90 day comment period and at least seven regional public hearings on the "Draft Supplemental Generic Environmental Impact Statement for gas drilling in the Marcellus Shale and other like formations" that the Department of Environmental Conservation has released (DEC). As you know, the Final DSGEIS will largely determine the regulatory regime under which permits would be issued for gas drilling in the Marcellus Shale.
As an angler in the northeast, I could be directly affected by gas drilling and high-volume hydraulic fracturing. I am deeply concerned about the potential natural resource and recreational impacts from those processes. Further, the technical and environmental issues associated with this proposed industrial activity are complex and extensive; and citizens should be given more time to interpret and digest the contents of the DSGEIS.
I hope that the DEC will provide for a 90 day comment period but more preferably 6 months and hold at least seven regional public hearings that are convenient and accessible to interested parties, including at least one hearing in New York City.
Thank you.

Very truly yours,

Your Name

In class we've been studying taxonomy - the system by which life scientists classify, or group, living things. Today we grouped Teddy Grahams by similarities and differences.

As we learned, all life on the planet used to be grouped as either a plant or an animal. However, as we learned more about science and especially since the technology to analyze DNA has come about, we have had to change a lot of how we grouped living things. Modern taxonomy is based on DNA similarities and evolutionary relationships. In addition to grouping living things, scientists also try to fit together extinct species into the "tree of life". There was a major find today in the news that illustrates this. The news story is found here.

The following students got a perfect score on today's vocabulary quiz: Camille, Savanah, Sam G, Brandon, Courtney, Kelly, Sam N, Curtis, Zach, Tim, Chloee, Mackenzie, Amber, Alan, and Anneleise. Nice job guys. Remember, tomorrow is the last day of the 5 weeks so get those old assignments in!

02 October 2009


Today we set up our vermicomposting bin (composting food scraps with the help of worms called Red Wigglers). We created a moist environment with plenty of shredded newspaper and put in some leftover salad, old squash, and an apple core. These guys love to eat so we will be adding food scraps 3 or 4 times a week. In return we will get rich fertilizer called worm castings.

My highschool class is currently studying forestry. Today we cut up some "beaver cookies" to study tree rings. We started out the old-fashioned way but soon had to revert to the chainsaw to finish up. Above, Mr. Stegeland and Donovan give it a shot while Jesse looks on. Thanks to Groton resident, Mr. Billups, for donating the Norway Spruce log. Here is a short video:

Today we reviewed metric measurement and collected the slug lab write-ups. We will be having a test Wednesday on measurement and the scientific method. Please stop by if you need help with anything. Tomorrow in class we will review for the test.

17 September 2009


Today we checked the results of our slug labs. Yesterday's featured group learned that their slug preferred plain lettuce over coffee-flavored lettuce. Did anyone else run this same experiment? What did you get? These lab writeups will be due Monday. They will be worth quite a bit so make sure you fill all of the lines with your answers.
That's right Kenny! These may also be submitted via email.
