Snakes are misunderstood. They are an important part of the food web, and many of them eat rodents - vectors for zoonotic diseases. There are over 42 species in Georgia, and only six of them are venomous (there is no such thing as a poisonous snake)! While there are over a thousand reported snake bites every year, there are only an average of 5 deaths per year across the entire United States. Most folks who get bit are trying to remove or harass a snake, and they are typically bitten in the arm. The most important thing you can do is learn to identify different snakes in your area (for example: there are no Water Moccasins in Cobb County, but there are five other large, non-venomous water snakes) and pay attention when you are hiking in the woods or playing around leaf litter or fallen trees. Here are four common snakes that do have some similar coloration. The only dangerous one is the Copperhead, the ONLY venomous snake in Cobb County.

Creating Compound Machines: Part 1 of 2.
Mrs. Kappel's class found out that building a complex machine from scratch is no easy task. Students are spending the next two classes taking two cracks at creating a machine to lift our "tigers" at least 4 inches, and setting down in a different place.
Classification - a field study.
Mrs. Stone's fifth grade class took to the Nature Trail to study vascular/non-vascular plants, and vertebrate/invertebrate animals. We found examples of everything and recorded them in our journals back in the Nature Nook.
Drawing inspiration from play.
Our second graders are in the imagine/explore phase of their latest STEM challenge. We've been studying how the sun and moon appear to move through the sky and learned about UV rays in order to help Suzi/Angelina/Mylo come up with a way to not overheat on the playground. We'll be making models next using pipe cleaners, screens, aluminum foil, modeling clay, etc. Below, Ms. Gardner's class is watching the 3rd graders at recess for inspiration on their projects.
Roll out with Mrs. East's class!
Mrs. East's class is taking the first shot at using our Kindergartner's new knowledge on forces, pushes and pulls, to design and build a structure to transport "rocks" from one place to another in order to construct something new on the original spot. We saw rakes, bulldozers, wagons and cars!
Wanderers
“Exploration is in our nature. We began as wanderers, and we are wanderers still. We have lingered long enough on the shores of the cosmic ocean. We are ready at last to set sail for the stars.” - Carl Sagan
About two years ago I read 2312, a murder mystery set in various places throughout our solar system. The most fascinating part was imagining how we'll slowly expand throughout the solar system. NASA's Jet Propulsion Laboratory released fun tourist posters of many of those locations (seen below), and artist Erik Wernquist created the following video, using the words of scientist and dreamer Carl Sagan. It is one of my favorites, and I thought I would share it with you all.
From the website: "Wanderers is a vision of humanity's expansion into the Solar System, based on scientific ideas and concepts of what our future in space might look like, if it ever happens. The locations depicted in the film are digital recreations of actual places in the Solar System, built from real photos and map data where available."
Leaving on a jet plane: I'll be back Wednesday!
As we've been using the Project Lead The Way curriculum in the lab all year, I was selected for a summer program with their organization that included a conference in Indianapolis this Monday/Tuesday. Sixty elementary educators from around the country and I were flown out and put up to learn how to teach other teachers about this curriculum. Then we were joined by 1800 people for the general conference. I listened to awesome keynote speakers and students, learned about the VEX Robotics kits, and took a behind the scenes tour of the zoo! Fortunately I am better at taking pictures during class, but here is one with Angelina, Mylo and Suzi from our PLTW stories.
Design Process in action
What better place to draft amazing design plans than the Tritt Nature Nook on such a beautiful day...
Ground-level Ozone
We are taking a look at chemical changes in fifth grade. For the last two weeks we've learned how transportation choices affect the air quality in Georgia, and participated in a nation-wide cartoon strip contest to educate our peers - this week we are creating homemade ground-level ozone detection strips. Ground-level ozone is harmful to breathe in; we really just want it higher up in the atmosphere to help protect us from the sun's rays.
Using the charts below we can check how much ozone is in the air in our community. This more of a problem in the summer, as the heat from long days breaks down volatile organic compounds into increasingly unhealthy stuff.
Showing real growth -
In first grade we "planted seeds in ziplock bags with some water and hung them in the windows to see how they would start to grow. We are sketching the changes we find over a couple of weeks. We have a real goldielocks situation here, where some are too wet and others are too dry. To be continued!
Afterwards we pulled some weeds in the Nature Nook to make room for crops, and along the way found feathers from a bird we think was eaten by a hawk!
When the moon hits your eye like a big pizza pie...
... that's light being reflected off the sun! Using flashlights and Styrofoam balls wrapped in aluminum foil, we are partnering up in 2nd grade to see how light reflects off of the moon and into our eyes on Earth.
Math Night
Join us for Math Night on March 24, 2016! It takes place at the Publix on Shallowford Road (at Johnson Ferry Rd.) from 5-7:00 p.m. Math Night presents students with an opportunity to extend their mathematical understanding in a real-world context. Parents get a first-hand look at how their children apply understanding and may even learn something new themselves. Students see that Math is relevant and fun, and we all connect with a great resource and partner in education. The Papa John’s pizza truck will sell pizzas for $10 a pie. Pick one (or more!) up for dinner. Teachers at the front of the store distribute grade-level problems, clipboards, and pencils. Kids and their parents then go on a scavenger hunt to answer questions. The answer sheet acts as a homework pass for the following day. Be sure to download a QR code reader so kids can check their answers. Please note: Teachers will have a few extra sheets for students who have a conflict on Thursday night but who wish to complete the scavenger hunt and problems over the weekend. Any students completing the task over the weekend should submit their sheets on Monday; teachers will work with those students to arrange for a homework pass.
Congratulations 2016 Science Fair winners!
Georgia Tech hosting free STEM career fair for children
The nonprofit organization Science, Engineering and Mathematics Link, Inc. (SEM Link) is hosting its 9th Annual STEM Career Fair and Exhibition. It will be held on Saturday, April 16 from 10 a.m. to 2 p.m. at Georgia Institute of Technology. Admission to the career fair is free and will provide K-12 students with an opportunity to explore careers and meet and interact with professionals in these fields. Learn more and GET TICKETS here: http://m.ajc.com/news/business/employment/stem-career-fair-will-give-kids-opportunity-learn/nqcnx/
Not so simple machines...
Mrs. Waters' class tackled pulleys using the VEX kits and Invention Publisher app as we continue to explore simple machines in fourth grade.
Oobleck!
Named for Dr. Seuss' "Bartholomew and the Oobleck", this non-Newtonian liquid is made from just corn starch and water - apparently the messiest (but coolest) combination around!
Thanks everyone for the Valentine's Day notes!
STEAM in (lights... camera...) Action!
The band OK Go is at it again. I like their music, but the videos they produce are STEM/STEAM up and down and back. Check out the newest one below (shot in zero gravity), but be sure to look at the Rube Goldberg machine video too. The lyrics and themes are pretty acceptable.

For any future physicists: Einstein’s ripples in spacetime final seen!
"Far from our galaxy, in the vast darkness of space, two massive black holes merged into a single, larger hole. And now researchers say they have detected rumblings from that cataclysmic collision as ripples in the very fabric of space-time itself. The discovery comes a century after Albert Einstein first predicted such ripples should exist." Read more from the NPR article here:
