Thank You!
I want to say how grateful I am for my Science class, for my class mates, and my professor. In just 3 weeks, I have learned so much and gained more confidence than I ever thought I could. It is refreshing to be in an environment where people support each other, rather than put each other down. Where if you don't understand something, you're not afraid to admit it because your peers voluntarily and openly share their information and ideas, rather than covering them up. Where it's OK to guess, because there is no wrong answer when every answer will help guide us towards what we're looking for---knowledge and understanding of the world around us. Where we can learn from each other's knowledge, experiences, and opinions in a community where we can truly work together to help each other rise, so we can in turn help our children rise, learn, achieve, and thrive. I'm going to miss this class, Thank you for opening my eyes to this new world of teaching and learning!
A Day at the River
During our Project Wet activity, we got to go to Stones River and observe what was in the water! We learned how to tell if water is clean or polluted by the fish and organisms we found in the water. I had no idea you could tell how clean the water is by taking a small sample of a few creatures in it. We put the ones we found in ice trays to observe, and then let them go unharmed when we were done. It's amazing what you notice when you really look! It turns out the part of Stones River we examined was pretty clean! But we have to be so careful of what we put down our drains, because it can end up in our rivers and lakes.
Call 811!!!
So the other day, we had a phenomenal guest speaker, Mr. Swoape. He is from the gas company---the natural gas company. I learned so much from him. He taught us that in order to start a fire, (DON"T TRY THIS AT HOME OR ANYWHERE!!!!) you need 4 things: oxygen, fuel, a catalyst, and what's the fourth?---MATH!!! I thought you only needed the first 3 things. It turns out the proportions of oxygen and fuel have to be right to start a fire.
Mr. Swoape also taught me that when I'm metal detecting, if I'm going to dig deeper than just a couple of inches, or if I'm going to plant a tree, I need to call 811 first. It's a FREE service, where the gas company will come out and make sure there are no gas lines running where I want to dig, so I don't bust a pipe and put myself and those around me in danger. Natural gas is actually harmless until there is so much of it, that it starts taking the place of the oxygen or it lights on fire! So if you smell something that smells like rotten eggs, a skunk, or a dirty diaper, it might be a leaky gas line, so GET OUT OF THE BUILDING AND TAKE ELVIS WITH YOU!!! I also learned the different colors of each utility. When you see these lines on the ground, here's what each color means:
White- Dept. of Transportation
Red- Electric
Blue- Water
Yellow- Gas
This presentation was awesome! I would love to have him present in my classroom one day. It was so exciting! I wish I had taken a picture of it..I picked the wrong day to forget my phone. For a picture and a little more info, check out Kim Geary's blog:

Poem Tree!!!
This Project Learning Tree activity combined my love of poetry with my love of trees!!! I loved being able to go outside on my own and write poetry about a tree! During this exercise, I wanted to observe a big tree, so I searched for my tree a little further than the rest of the class. I was so tempted to climb it and write my poem in the tree! This showed the class and myself that in our own classroom outside activities, we have to set parameters for our students or they might wander off like I did!
This isn't my original poem from class, but my original poem was about a maple tree. This poem is a true story about my maple tree at home. I traced the biggest leaf on my baby maple tree. It's only about 2 years old, and look how big its leaves have gotten!
I can't wait to do this activity in my future classroom. I loved the idea of shaping it like a tree or like the tree you observed, and it doesn't even have to rhyme.
THIS IS A PICTURE I TOOK FROM THE FERRIS WHEEL AT BONNAROO WHEN I FIRST MOVED TO TENNESSEE ABOUT 5 YEARS AGO. I LOVE HOW IT SELFLESSLY PROVIDES SHADE FOR PEOPLE ON A VERY HOT DAY! <3 :)
Veggie Garden in the Classroom!!!
One of our Project Learning Tree
activities was that we had a few different food items on the
table, and in groups we had to guess where each item came from. For
example, olive oil comes from an olive tree. Gum originally came from
chicle (the word for gum in Spanish!), which is a sap that comes from
the sapodilla tree. This exercise is a great way to get people to
think about what they're eating. Tennessee ranks one of the highest
in obesity rates. In school, I remember having the DARE program,
which gave us information on why not to do drugs, drink alcohol, or
smoke cigarettes; but I don't remember learning about the effects
that the food we eat can have on us. We hear how smoking can cause heart
disease, but obesity is also a major contributor to heart disease (which is
the number 1 killer in Tennessee). Obesity is just one health problem
that poor eating habits contributes to; there's also diabetes and other health
problems. Type 2 Diabetes was once rare among children. Now, the
number of children with Type 2 Diabetes is increasing, due to
obesity. When children (and adults) become aware of where the food
they're eating comes from, when they realize that we consume so many ingredients we can't even pronounce, when they
learn how to read nutrition labels, they become more aware of what they're putting into their bodies and are more likely to adopt wiser
eating habits. When I went to school, we did discuss the food
pyramid, but it didn't really get the point across. This is where the
Plate Method comes in handy. This exercise is a good way to implement
the Plate Method.
I have seen the Plate Method at work; I have seen adults and children lose weight on it and better
control their diabetes with it. The Plate Method basically says that
half of your plate is vegetables (non-starchy vegetables), a quarter
is your protein (which doesn't have to be meat; it can be beans or
other forms of protein), another quarter is your starch, and you can have 2
more starches with it, with each one being either a glass of milk, a
tortilla, a piece of bread, a fruit, etc. You also have to keep the
size of the plate in mind. The size of our dinner plates have really
grown from what they used to be in the past.
I can't wait to implement healthy
eating in my classroom! It is so important! Along with this exercise,
you could start a little herb garden by the window in your classroom
or even start a school vegetable garden! When children grow their own
vegetables, help their parents pick them out at the grocery
store, or assist in preparing the food they're going to eat, they are
much more likely to try new vegetables. Chop Chop magazine is a great
resource for getting kids to eat healthier. It has fun, easy, healthy
recipes they can put together on their own. I got a few tips from
this magazine that I use at home. For example, you can save about an
inch of the carrot tops and put them in a jar or bowl half covered in
water; soon it will start growing little leaves you can put in your
salads or food to give it a great healthy flavor! You can also keep
about an inch or two of the root tip of your green onions, put them in
a jar with water covering half of the vegetable, and it will grow new green
onions! It saves you money, and it's the part you probably throw away
anyway, and it's healthy!!! You can grow these things very easily in
your classroom with very little care. All you have to do is add a
little more water when it starts getting low. Check it out!

The Health Department has free classes for schools where students get to cook and receive their own chef
hats, aprons, and a plate method plate. They love it! Look into it
for your classrooms. The Health Department's phone number in
Murfreesboro is (615) 898-7880. Ask for LaShan Mathews or Aubrenie
Jones.
I'm all about children eating healthy
to prevent them from getting deadly disease when they grow up. And the kids will take what they learn home, and even get their families to start eating healthier!!!
Here's a book that would go great with this lesson!!!

Sounds of Silence
Our Project Learning Tree lesson on sound made me think about silence and the sounds of silence. Our society puts a negative connotation on silence. It is seen as a tool for oppression or as a symptom of sadness. This doesn't hold true in all cultures. In an anthropology class I took in college, I learned about some of the different ways other cultures portray silence. For example, I've heard that to some Japanese, it's rude to not take a moment to think when someone asks you a question. This makes sense to me. I notice that when someone asks me something and I take a quiet moment to think about what they've asked me, they keep talking to fill the silence. In the classroom, when a teacher asks a question, students are expected to answer right away. I usually felt I needed a little time to think about what I was going to say before I raised my hand, and I often didn't have that time to in school. By the time I thought of what to say, the discussion had moved on. Some teachers would see this as me not wanting to participate, or they thought I was shy.
Silence between two or more people doesn't have to be "awkward silence;" it can be a sign that you're comfortable. In a conversation, you might feel like you have to keep saying something back and forth. For me, sometimes I want to talk or listen to music and sometimes I want silence. (Note: When I say silence, keep in mind that our world is never completely silent, due to ambient noise). Silence helps me clear my head and think. Silence helps me learn, because I can't hear others or what's going on around me as much if I'm talking. So often people ask me if I'm OK because they say I'm being so quiet. Why do people associate silence with sadness? You can be sad and quiet, or you can be sad and want to talk about it. Or they say, "you're shy," or "are you mad?" In our society, sometimes people feel like they need to fill every moment with words or some kind of sound, like music or the TV. This is sort of like how people think they need to fill space with material things like furniture. Empty space (which in reality is not empty at all) can be peaceful and liberating, like the desert.
Silence can help you clear your mind and improve your concentration to learn, work, or focus on a specific task more efficiently. Don't get me wrong, discussing, collaboration, and learning from each other through the use of words is extremely important, as well as speaking out when injustice is being done. I'm an English major---I love words and sharing information, but in our noisy world, the proper use of silence is also important, not just for peace of mind but also for being aware of your surroundings, observing, and learning. I like how during our Adopt-A-Tree exercise, we were asked to observe a tree in silence. It's important to see, hear, feel, smell, and taste while you're not talking so you can fully experience your senses. When you talk at the same time you do something, you're thinking about the words you're going to say while you observe, so you're multi-tasking and not providing your full attention and all of your senses to the exercise of observing or the task at hand. Collaborating is also very important, because someone else might notice something you did not. The process of observing and learning is important to do both in silence and through words, on your own and with others.
I had a hard time finding articles on the positive side of silence, but here are a couple. De Geest's The Negative Persona of Silence is on how our society views silence as something negative:

Sally Jones' Speech is Silver, Silence is Golden: the Cultural Importance of Silence in Japan touches on how people view silence in different ways:
http://wfae.proscenia.net/library/articles/de_geest_persona.pdf
Sometimes, I need quiet time to myself to recharge my batteries. Some people mistake wanting to do "nothing" for laziness. Stillness is not laziness.
This blog touches on that and the importance of stillness in this fast-paced world:

This book would be perfect to read out loud with the PLT lesson on sound. I love it!
Something to think about: In music, the resting notes in between melody notes play a major role in the composition of the song.
I like the idea of implementing "Slow Down to Speed Up," in the classroom. (I'd like to learn more about this concept for another blog).

Earth's Journey Through Space
So thinking about moss and why one might
judge direction based on where the sun is shining made me think of
the Sun, the Earth's tilt, and the seasons again; so I started
researching it, since I still didn't feel very confident on the
explanation of the Earth's tilt in relation to seasons. I had to
visually see it in motion to grasp the idea, so I looked up some
videos. This particular one made it click for me. The smaller square
on the bottom left shows the Earth on its axis as it orbits the Sun.
By visually seeing this phenomenon rather than trying to visualize it
in my head, I was able to better understand the process.
While I was watching this video, I started thinking about the way our solar system sort of spirals through space around the center of the galaxy. I had never really thought about it like that before. From seeing diagrams in books, I had usually pictured the solar system orbiting the Sun like on a flat plane (hmm...like how they used to think the Earth was flat), so I did some more research and found this video on Youtube. There might be some misconceptions in this video, but I liked this 3-D way of looking at it. If you watch it, watch it until the end. It gets a little repetitive, but how it ties in at the end is eye-opening. The helical motion of Earth going around the Sun mirrors life on Earth, from the pattern of a flower to a seashell to our DNA!!! Think about the seashell exercise we did in class, and how some of the seashells had spiral, or helical patterns, like the Earth's path and the shape of our galaxy!
This got me thinking about how fast the Earth is really travelling. We usually think of the Earth as travelling at the speed it takes it to revolve around the Sun, which pretty much takes a year. But what about the speed that the Sun along with our solar system is travelling around the center of the Milky Way galaxy? This is called a cosmic year. A cosmic year is about 225-250 million years! The Earth is travelling around the galaxy at 500,000 miles an hour!!! Our galaxy, the Milky Way, is 100,000 light years across! And that's just one galaxy part of clusters upon clusters of galaxies!
