Interesting News about an Aztec Pyramid

Reuter's is reporting that archaeologists have discovered ruins of an ancient Aztec pyramid that may prove that the civilization is at least 100 years older than anyone has previously thought.

Capture / Recapture Modelling -- Math Class

Wildlife biologists use a method called capture / recapture to estimate populations of animals in the wild. For example, if a biologist wants to know how many deer are in a particular forest, or how many trout occupy a certain pond, it is impossible to capture and count all of them. Capture / recapture is a method which involves capturing a certain number of animals, tagging (or marking) them in some fashion, releasing them back into the larger population -- and then taking repeated periodic samples from the population to count how many of the tagged animals are recaptured in the sample groups. Mathematical proportions can then be used to calculate the estimated number of animals in the larger population.

That's exactly what we did in class -- we introduced a "tagged" sample of multi-colored goldfish crackers into a "pond" of the more common goldfish crackers. Then we recaptured samples from the ponds and counted how many tagged fish there were in each sample. We used those samples to calculate estimated numbers of fish in our ponds... It worked pretty well (except in a few cases where some of our samplers ATE the fish!!!). EEEEEKKKKK!

Studying Ancient Greece

Sixth graders have begun studying the culture of Ancient Greece. In the classroom, they are moving from "station to station" creating maps of the important locations, making "trading cards" based on Greek gods and goddesses, doing some textbook research to learn about Greek culture, government, art, philosophy, etc., and even making traditional Greek Komboloi (prayer beads).

Giving to Others

We have three different projects going on right now that students can participate in as we think of ways to share our gifts during this season of preparation for the birth of the Christ Child in our midst.

The Nativity Student Council continues to collect canned goods to help those in need through the holidays. Each of the 6th grade classrooms would, ideally, contribute a minimum of 100 items toward the schoolwide goal for this project. I'm not sure how many cans have been collected by Room 205, but I know that my homeroom has a total or 18 cans so far -- we have a ways to go!

The 6th Grade Girl Scouts are working to collect toys for the kids at Children's Hospital. The items that they gather will be donated to help brighten the lives of children undergoing treatment for cancer. Students received a detailed list of needed/wanted items, and the collection will end next Tuesday, December 18th. Whatever you can add to this effort can be placed in the decorated boxes in the 6th grade classrooms.

Lastly, the 8th graders are sponsoring a drive to help Lighthouse Youth Services (a comprehensive youth and family services organization, providing programs including emergency shelter, residential treatment, foster care, etc.). Eighth graders are collecting toiletries, towels, t-shirts, socks, watches, etc. Their goal is one donation per Nativity student. Donations can be dropped off in the Nativity Cafe' anytime before December 20.

Won't you think about what you can give?

African Stories

As students have studied ancient African culture and history, one of the aspects that they learned about was the tradition of the Griot, or storyteller. Small groups of students worked together to dramatize some traditional African tales for their classmates. We found that stories often teach a lesson...

Probability and Area

As we continue to study probability, we've moved into looking at how probability relates to area... how can we make predictions about where an object might fall, land, hit, etc., based on the area of the target? Students began this particular exploration by dropping barley onto a target grid... We will transfer what we are discovering about all of this to questions of how likely it is that we might be in the section where those prize T-shirts land at Great American Ball Park, or what are the probabilities of scoring on your opponent when playing a game like "Battleship."

Worms!

We are studying worms, echinoderms, insects, mollusks, arthropods, sponges and echinoderms in science. Students are working in teams to prepare and present lessons on various topics as we work through this matierial. Here we are -- learning about WORMS!

Communication

I am starting to feel a little like this fellow...

This week, I have 22 students who have not returned their signed notes indicating that parents have seen their graded homework packets -- over half! That means that I will spend class time again tomorrow checking with those students and trying to get them to bring in those signed notes. I hope a few more will be returned. And likely more on Thursday, and probably, I will end up assigning some sort of "penalty" assignment because some significant number of them will not ever return those notes that I so diligiently produce every single week.

I think it is important for me to keep parents informed of the work that their students are doing in my classes. I think it is important for parents to be able to see what students are turning in -- or not turning in. I think it is a valuable thing for parents to be informed about upcoming tests and classroom events. That is why I try to be so consistent with those weekly packets. Clearly, though, some students do not feel any particular pressure at home to PRODUCE that weekly packet of graded work and the note from me that accompanies it.

Sigh. That is a significant tool for me to communicate with parents. If it doesn't get home on a regular basis, the loop is broken. I can't be sure that parents know what's happening with their students. In fact, I become pretty suspicious that parents probably really don't know what their student is doing in my class. Otherwise, I'd be getting those notes back -- every week. Without fail.

Music Hall

Tomorrow we'll head off to Music Hall for our annual field trip to enjoy the musical artistry of the Cincinnati Symphony Orchestra. If you don't know much about the actual building itself, here's just a little bit of the "history" and story behind this lovely Cincinnati landmark --

Built in 1878 with private money raised from what is believed to be the nation's first matching grant fund drive, this Cincinnati showpiece has been renovated and updated and includes what is judged to be among the best and most beautiful concert theaters in the world.
Springer Auditorium - The Springer Auditorium is known the world over for its extraordinary acoustics and its lavish old world decor. With its plush seating for 3,516, it serves as home for the Cincinnati Symphony Orchestra, the Cincinnati Opera and the May Festival Chorus, among other local performing arts organizations. In addition, throughout the year it hosts a large number of touring performances, conferences, concerts and awards ceremonies. The fully-equipped stage with a complete lighting system, hydraulically-operated orchestra pit and roomy backstage area make any type of production or performance possible.

Seven Ethical Tests

There almost always comes a time in the sixth grade year when students begin to find themselves facing choices about a variety of issues. It just seems that, as young people reach the age of 11 or 12, there are things that have previously been defined by parents that, increasingly, become more a matter for students to control for themselves. This is the time of the year when students have to determine what to do about including others, what to do about handling their responsibilities, what to do about being honest and fair, what to do about treating others with kindness and respect, and what to decide about things like cheating on assignments and tests.

One recent study that I read about asked students in the upper primary grades and in middle school to answer questions like these:

1. We are playing Monopoly and I roll a 2 with the dice. If I move there then I land on someone's property. If I land there, I have to pay somebody money. Is it okay if I just go ahead one more space? 2. You are asked to draw a picture in Art class. The teacher wants you to draw a picture of a cat but you are not very good at it. You ask your friend to draw it for you. The art teacher thinks you drew the picture and gives you a good grade. Is that okay? 3. You are out on the playground and see a toy like a hot wheel, beanie baby, or a pair of sunglasses that someone left outside. No one is going to see you pick up this toy, so you get it and take it home with you. Is that okay? 4. Your mom and dad see that you have a new toy and they know they didn't buy it for you. They ask you where you got it. You tell them a friend gave it to you. You don't tell them you found it on the way home and just picked it up. Is that okay? 5. You are taking a test in spelling. You don't know how to spell a word. The person sitting next to you has the answer. The teacher is not looking at you so you look at the other person's paper and write the answer. Is that okay? 6. A teacher sees you talking in class and sends you to the principal's office. You tell the principal that you weren't talking and that you were just listening, but actually you were talking. Is that okay?

What researchers found was that, once students were really old enough to know what was "right" and what was "wrong" the number of times that seemingly "wrong" choices were viewed as "okay" decreased but still remained much higher than most people are comfortable with. The motivations are varied but if students see that it is important to get good grades or remain popular or obtain a certain level of performance, then they will choose in ways that they identify as "wrong" under other circumstances.

Clearly, it is very difficult for young people to choose to act in alignment with the values and beliefs which they know and have been taught. In the moment when a student is faced with a difficult ethical choice, it is important to have TOOLS or TESTS to apply to the situation in order to help make the right decisions -- the ones that will be "right" and not just "easy." How does a young person make those judgements?

Thomas Lickona, who is a well-respected author and educator on the subject of character, proposes that it is possible to evaluate most situations using these seven ethical tests:

1. The Golden Rule (reversibility) test: Would I want people to do this to me?
2. The what-if-everybody-did-this test: Would I like it if everyone else acted this way?
3. The parents test: How would my parents feel if they found out I did this?
4. The religion test: Does this go against what my religious faith teaches?
5. The conscience test: Will I feel guilty afterwards?
6. The consequences test: Might this have bad consequences, now or in the future?
7. The front-page test: How would I feel if my action were reported on the front page of my hometown paper?

Thank You Very Much

I wanted to take this opportunity to thank each one of you who have contributed to my charitable fund raising efforts (through the littel "gizmo" over there on the side of the page, or in person by check or cash). If you don't know much about the organization I'm trying to raise money for, then you can learn more here: The Arc Hamilton County. The "Arc" is an advocacy organization for people with developmental disabilities, and we work with them and their families to help ensure that they are able to fully participate in the life of our community. In these increasingly difficult economic times, the dollars needed to continue the work of the agency is very hard to come by. Without the help and support of donors like you, services and programs would certainly have to be scaled back or eliminated altogether. We just received our first check for a little more than $1700.oo from First Giving. The campaign will continue through the end of the year. I am so very grateful to each and every single one of you who have taken the time to give so generously. I know that there are many competing demands for your dollars and your generosity. Thank you for choosing to help those in our community who depend on the services of the Arc. Sue Daniel

Feed the Hungry -- Improve your Vocabulary

Here's a website where you can play a vocabulary game and help to feed the hungry around the world. For every vocabulary word that you get correct, rice will be donated through the United Nations, to those who are suffering from hunger. The words begin at about the third grade level and increase in difficulty as you progress through the game. Give it a try...

Burnett Woods Field Trip -- Aquatic Environments

Today, we took a trip out of the building to Burnett Woods, to study aquatic environments. Even though the weather was rainy over night, it turned out to be a lovely, cool, sunny fall day. The park was truly beautiful, and we got a chance to learn about the role that water plays on our planet and in our lives.

We learned about the algae that form the basis of the lake ecosystem, and had a chance to actually see some up close, using some magnifying viewers. We tested the pH of the lake water, and found that our readings were generally between 7 and 8. The naturalists told us that these readings indicate that the lake is a pretty healthy environment for the organisms that live there. We played a game that helped us better understand the water cycle, and we even formed a "web of life," that gave us a good picture of what happens when one part of the web is damaged or destroyed. When we were done, we could se clearly that if even one plant, or one animal is lost from an ecosystem, the whole system is impacted.

After lunch, we took a hike around the lake so that we could see the animals that live in and around the lake. We got the chance to see a turtle, some frogs, some small fish, some ducks, and collect seeds from some of the plants that grow around the edge of the lake. Back at the nature center, we had a short time to learn more about animals like the beaver and the red-earred slider who live in this habitat.

It was a very good day.

Ancient China -- Our "Mini-Museum"

As part of our social studies exploration of the culture and history of Ancient China, students worked with a website put together by the British Museum. After completing their "virtual tour" of the museum exhibit, they created their own pieces modeled on artifacts like oracle bones, and the jade bi. They made figurines of the goddess, Nu Gua, and diorammas of ancient burial tombs. Our mini-museum is on display in the hallway on the second floor. Parents and friends are invited to stop by and see what we've created.

Experimental Probability

We are starting to learn about the differences between theoretical and experimental probability. In studying experimental probability, we will work with a variety of simulations -- ways of recreating or simulating real life situations so that we can see what might really happen, and compare that with what mathematics predicts will happen "theoretically." It makes for a lot of "shaking and spinning and rolling and flipping" in math class...

Confucius

One part of our study of ancient China has been learning about the philosopher, Confucius. Students learned that this "master," or teacher believed that each person should lead a life of virtue, and that, in this way, an orderly society would be created. In the collected writings of Confucius, The Analects, we find this --

Be humble, obedient, trustworthy, and loyal. Maintain high standards in those with whom you associate, serve, and/or emulate.

As part of the work that we did, then, students chose a virtue that they felt was part of their own lives, and then chose a Chinese calligraphy character that represented that virtue and brushed that character in paint. They wrote a short piece describing how that virtue is illustrated in their life.

Here are some pictures of students at work on the calligraphy --

We are well into our annual food drive, collecting good things to share with those in our community who may need a bit of assistance through the holidays. So far, our class has collected 45 items to add to the school total. We'd like to gather at least 100 items -- more if possible.

Don't forget to check the pantry and the cupboard, and see what there is that you can find to share. We've gotten off to a great start. Let's keep it up!

Remember Our German Students?

Here are some pictures from the morning that the 6th graders spent visiting with the students from Germany...

It was quite a conversation! Students discussed favorite activities and families, and politics and... well, you name it, they talked about it. It was an altogether enjoyable morning.

Two Bears -- A Probability Problem

There are two bears - white and dark.

We may reasonably ask several questions:

1. What is the probability that both bears are male? Writing 'm' for male and 'f' for female and counting the lighter bear first we get four possible outcomes (ff, mf, fm, mm) of which only one should be considered favorable. The answer, therefore, is 1/4.

2. Now assume I told you that one of the bears is male. What is the probability that both are males? Of the three possible outcomes (mf, fm, mm) only the last where both bears are male is favorable. The answer is 1/3.

3. Now the last question. I am telling you that the lighter bear is known to be male. What now is the probability that both of them are males? Please stop for a while and think of the problem. Try to answer the question before looking into the solution.

Discovery Update

If you have not been following the work going on during the space shuttle mission, here's an update --

In one of the record-setting five space walks scheduled for this space shuttle mission, astronauts swung open the door to their new space station addition Saturday and floated into the spacious and sparkling white room, formally christening it Harmony.
Even though it looked immaculate inside, international space station commander Peggy Whitson and Italian astronaut Paolo Nespoli — the first to enter — wore surgical masks and goggles to protect themselves from any dirty stowaways, like dust, lint or crumbs. The air inside the school bus-size chamber was immediately tested.
Harmony was named by schoolchildren in America but made in Italy, and Nespoli proudly noted that as he bobbed up and down in the 24-foot-long, 14-foot-diameter chamber that was delivered by shuttle Discovery.
The European Space Agency's science laboratory, named Columbus, will hook onto Harmony as early as December. The Japanese Space Agency's lab — called Kibo or in English, Hope — will latch onto Harmony early next year.
Harmony also will function as a nerve center, providing air, electricity and water for the space station. It was launched with racks of computer and electronic equipment. All this gear had to be locked down for the jarring rocket ride to orbit, leaving the astronauts to undo more than 700 bolts to free up the equipment.
Perhaps just as important, Harmony will provide extra living space for the three space station residents. It is the station's seventh room; the first one was launched in 1998.
The space station's crew will move Harmony to its permanent location after Discovery leaves in another week. Until then, the astronauts will be restricted on how long they can spend inside the new compartment because of the makeshift ventilation system currently in place.
