Too many different resources!!!
Okay, seriously.... it is getting to the point where my tool box is FULL. I pretty much would implode if I did not have a MAC with a keychain to remember my passwords and screen names. I mean, it is great to have all these tools, but trying remember all this I end up having to request my screen name or my password on a pretty regular basis. I have finally come up with a screen name that I can normally count on getting. I went through a few....Daver is normally not available.....Burritoman was my first incarnation...then I had Bratwurstboy for a while.... now I have so many different email accounts that I can not find where my screen name or pass word is being sent to. I have all my mail from my MSU account forwarded to my U of M account, but I no longer remember how to change my settings on my MSU account. I can not even get into my eastern michigan account. I have a hotmail account that I have not been since U of M started a webmail server. I use to use telnet, but I think the webmail is better. Anyway, as an environmentalist I wonder what kind of consequences my online actions are having. Liz was telling us that all internet stuff was being archived, I wonder what it takes to archive all this information....how often are they upgraded? It reminds me of a great article I read.
Where Old Computers go to Die....and Kill!!! Below is an excerpt from the article if you would like to read it just search the title in google.

Where computers go to die -- and kill
More than 50 percent of our recycled computers are shipped overseas, where their toxic components are polluting poor communities. Meanwhile, U.S. laws are a mess, and industry and Congress are resisting efforts to stem "the effluent of the affluent."
April 10, 2006 | A parade of trucks piled with worn-out computers and electronic equipment pulls away from container ships docked at the port of Taizhou in the Zhejiang Province of southeastern China. A short distance inland, the trucks dump their loads in what looks like an enormous parking lot. Pools of dark oily liquid seep from under the mounds of junked machinery. The equipment comes mostly from the United States, Europe and Japan.
For years, developed countries have been exporting tons of electronic waste to China for inexpensive, labor-intensive recycling and disposal. Since 2000, it's been illegal to import electronic waste into China for this kind of environmentally unsound recycling. But tons of debris are smuggled in with legitimate imports, corruption is common among local officials, and China's appetite for scrap is so enormous that the shipments just keep on coming.
In Taizhou's outdoor workshops, people bang apart the computers and toss bits of metal into brick furnaces that look like chimneys. Split open, the electronics release a stew of toxic materials -- among them beryllium, cadmium, lead, mercury and flame retardants -- that can accumulate in human blood and disrupt the body's hormonal balance. Exposed to heat or allowed to degrade, electronics' plastics can break down into organic pollutants that cause a host of health problems, including cancer. Wearing no protective clothing, workers roast circuit boards in big, uncovered woklike pans to melt plastics and collect valuable metals. Other workers sluice open basins of acid over semiconductors to remove their gold, tossing the waste into nearby streams. Typical wages for this work are about $2 to $4 a day.
Jim Puckett, director of Basel Action Network, an environmental advocacy organization that tracks hazardous waste, filmed these Dickensian scenes in 2004. "The volume of junk was amazing," he says. "It was arriving 24 hours a day and there was so much scrap that one truck was loaded every two minutes." Nothing has changed in two years. "China is still getting the stuff," Puckett tells me in March 2006. In fact, he says, the trend in China now is "to push the ugly stuff out of sight into the rural areas."
The conditions in Taizhou are particularly distressing to Puckett because they underscore what he sees as a persistent failure by the U.S. federal government to stop the dumping of millions of used computers, TVs, cellphones and other electronics in the world's developing regions, including those in China, India, Malaysia, the Philippines, Vietnam, Eastern Europe and Africa.
Because high-tech electronics contain hundreds of materials packed into small spaces, they are difficult and expensive to recycle. Eager to minimize costs and maximize profits, many recyclers ship large quantities of used electronics to countries where labor is cheap and environmental regulations lax. U.S. recyclers and watchdog groups like Basel Action Network estimate that 50 percent or more of the United States' used computers, cellphones and TVs sent to recyclers are shipped overseas for recycling to places like Taizhou or Lagos, Nigeria, as permitted by federal law. But much of this obsolete equipment ends up as toxic waste, with hazardous components exposed, burned or allowed to degrade in landfills.
BAN first called widespread attention to the problem in 2002, when it released "Exporting Harm," a documentary that revealed the appalling damage caused by electronic waste in China. In the southern Chinese village of Guiyu, many of the workers who dismantle high-tech electronics live only steps from their jobs. Their children wander over piles of burnt wires and splash in puddles by the banks of rivers that have become dumping grounds for discarded computer parts. The pollution has been so severe that Guiyu's water supply has been undrinkable since the mid-'90s. Water samples taken in 2005 found levels of lead and other metals 400 to 600 times what international standards consider safe.
In the summer of 2005, Puckett investigated Lagos, another port bursting with what he calls the "effluent of the affluent." "It appears that about 500 loads of computer equipment are arriving in Lagos each month," he says. Ostensibly sent for resale in Nigeria's rapidly growing market for high-tech electronics, as much as 75 percent of the incoming equipment is unusable, Puckett discovered. As a result, huge quantities are simply dumped.
Photographs taken by BAN in Lagos show scrapped electronics lying in wetlands, along roadsides, being examined by curious children and burning in uncontained landfills. Seared, broken monitors and CPUs are nestled in weeds, serving as perches for lizards, chickens and goats. One mound of computer junk towers at least 6 feet high. Puckett found identification tags showing that some of the junked equipment originally belonged to the U.S. Army Corps of Engineers, the Illinois Department of Human Services, the Kansas Department of Aging, the State of Massachusetts, the Michigan Department of Natural Resources, the City of Houston, school districts, hospitals, banks and numerous businesses, including IBM and Intel.
Under the Basel Convention, an international agreement designed to curtail trade in hazardous waste, none of this dumping should be happening. Leaded CRT glass, mercury switches, parts containing heavy metals, and other elements of computer scrap are considered hazardous waste under Basel and cannot be exported for disposal. Electronics can be exported for reuse, repair and -- under certain conditions -- recycling, creating a gray area into which millions of tons of obsolete electronics have fallen.
The U.S. is the only industrialized nation not to have ratified the Basel Convention, which would prevent it from trading in hazardous waste. The U.S. also has no federal laws that prohibit the export of toxic e-waste, nor has the U.S. signed the Basel Ban, a 1995 amendment to the convention that prohibits export of hazardous waste from Organization of Economic Cooperation and Development member countries to non-OECD countries -- essentially from wealthy to poorer nations. While this policy is intended to spur reuse and recycling, it also makes it difficult to curtail the kind of shipments BAN found in Lagos.
Despite a growing awareness of e-waste's hazards, the U.S. government, says Puckett, has done nothing in the past several years to stem the flow of e-trash. Given the Bush administration's reluctance to enact or support regulations that interfere with what it considers free trade and the difficulty of monitoring e-waste exports, the shipments continue. "Follow the material, and you'll find the vast majority of e-waste is still going overseas," says Robert Houghton, president of Redemtech Inc., a company that handles electronics recycling for a number of Fortune 500 companies, including Kaiser Permanente. As Puckett says, "Exploiting low-wage countries as a dumping ground is winning the day."

My Lesson Plan Using Claymation
Tuesday October 23, 2007
Michigan Science Benchmark for Cells page 8 of Michigan Curriculum Framework Science Content Benchmarks Summer, 2000 from www.michigan.gov/documents/Updated_Science_Benchmarks_27030_7.pdf
This is what we have worked towards for the past two weeks in chapter 7.
Cells (LC) III.1
All students will apply an understanding of cells to the functioning of multicellular organisms, including how cells grow, develop and reproduce:
1. Demonstrate evidence that all parts of living things
are made of cells.
Key concepts: Types of living things: plants,
animals; parts of organisms: tissues, organs, organ
systems; all functions of organisms are carried out by
cells. See LC-III.1 m.2 for specific functions.
Tools: Hand lens, microscope.
Real-world contexts: Common plant or animal cells:
Elodea leaf cells, onion skin cells, human cheek cells.
Single-celled organisms: Paramecium.
2. Explain why and how selected specialized cells are
needed by plants and animals.
Key concepts: Specialized functions of cells—
reproduction, photosynthesis, transport, movement,
disease-fighting. See LO m.4 (systems and processes
functioning to provide/remove materials to/from
cells).
Real-world contexts: Specialized animal cells: red
blood cells, white blood cells, muscle cells, bone
cells, nerve cells, egg/sperm cells; specialized plant
cells—root cells, leaf cells, stem cells.
1. Explain how multicellular organisms grow, based on
how cells grow and reproduce.
Key concepts: Specialized functions of cells—
respiration (see LO h.3), protein synthesis, mitosis,
meiosis (see LH-III.3 h.2). Basic molecules for cell
growth—simple sugars, amino acids, fatty acids.
Basic chemicals, molecules and atoms—water,
minerals, carbohydrates, proteins, fats and lipids,
nucleic acids; carbon, hydrogen, oxygen, nitrogen.
Cells come only from other cells. See LO m.4
(digestion).
Real-world contexts: The growth of plants and
animals.
2. Compare and contrast ways in which selected cells
are specialized to carry out particular life functions.
Key concepts: Classifications of organisms by cell
type—plant, animal, bacteria; selected specialized
plant and animal cells—red blood cells, white blood
cells, muscle cells, nerve cells, root cells, leaf cells,
stem cells; cell parts used for classification —
organelle, nucleus, cell wall, cell membrane;
specialized functions — reproduction (see LC-III.1
h.1, LH-III.3 h.2), photosynthesis (see LO m.3),
transport; cell shape.
Tools: microscopes
Real-world contexts: Reproduction, growth,
response, movement, etc. of animals and plants.
Functions of bacteria.
ISTE ED TECH Standard
Technology Operations and Concepts
Digital Citizenship
Students understand human, cultural, and societal issues related to technology and practice legal and ethical behavior. Students:
a. advocate and practice safe, legal, and responsible use of information and technology.
b. exhibit a positive attitude toward using technology that supports collaboration, learning, and productivity.
c. demonstrate personal responsibility for lifelong learning.
d. exhibit leadership for digital citizenship.
Students demonstrate a sound understanding of technology concepts, systems, and operations. Students:
a. understand and use technology systems.
b. select and use applications effectively and productively.
c. troubleshoot systems and applications.
d. transfer new and current knowledge to new technologies
Learning Performances: Identify the different stages of the cell cycle. Describe what happens to cellular genetic material during interphase and mitosis. Explain growth and the role mitosis plays. Give an example of cells that go through mitosis. Compare mitosis to unregulated cell growth.
Establishing purpose: Students have learned about cell structure and specialization. They can apply characteristics of life to infer if something is living. Students can recall cell theory. Now they need explain reproduction and growth of cells with regards to all life and the importance of these processes.
Materials: Projector and laptop, powerpoint, handout (worksheets from chap 8 in book, sec 8.2 pg 35 and sec 8.3 pg 36
Instructional strategies: Lecture, worksheet activity, video presentation
Time required: 5 minutes WDYK, 20 minute lecture, 5 minute video presentations, 5 minutes questions, 25 minutes worksheets
Cautions: Boring nature of material, must keep it interesting and class moving
Sources: Text book, Web videos, Mitosis Claymation
Instructional sequence: Lecture, presentations, worksheets
Objective:
I also borrowed this from a former MAC student, but to further drive home that Mitosis happens through a sequence, so often students think it is just 4 stages, but have no idea there are in between things happening and we just label stages to increase our understanding.
The lesson went really well, but ended up being a two day lesson to really finish it off. Here was the final part of the assignment. It was a mitosis flip book. I did not have cameras for students to shoot their own clay animation, so they made a book that they could flip to see the process.

My Claymation Project
This was pretty fun all in all, if not frustrating at times. I am happy with the over all product. Although Jordan copied us.
talk to you soon,

Guess what?
Today I logged on to my blog and found this message "I am a total tool for not logging out of a public computer. Maybe I'll learn some day." I am thinking that this is a result of my borrowed lap top's battery dying during the Friday Tech session. It actually feels like I have been violated. To have someone in my Blog posting as me. I did not think that when the computer died it would keep open access to this. It is strange, because even today when I went to post on this site myself I had to RE-ENTER my password, wonder why that did not have to happen with the borrowed PC.
Using the PC was a HUGE pain. I could not believe how many times it crashed and for the life of me I could not post my project from the PC I had to save it to my flash stick and post it from my MAC later.
I am back to being a luddite.
