Happy Friday!
I would like you to do a little digging and find out which elements on the periodic table are considered radioactive. Please create a list of them and describe what makes some elements radioactive and not others.

I would like you to choose a food that you eat frequently. Let's say SunChips. Go online to find the nutritional information and list of ingredients. All packaging is required to tell what is contained in them. Using the list of ingredients, I want you to identify exactly what makes up your food. For example it may say wheat, ok, we know what wheat is, but what if the ingredient is something like Thiamine Mononitrate. What is that? Well, that's what I want you to find out. Time to put on your detective hats and find out what you've really been eating :-)

Good Morning, you will have today and tomorrow to work on this catalyst. Please review the information and investigate further to help you answer the questions at the end.
Some groups claim to have cloned humans and that healthy babies have been born
using this process. However, scientists have been skeptical of these claims, as there
are still serious problems and limitations in animal cloning.
Read the following stories from the time the first claim was made of a human clone and
answer the questions that follow. Please feel free to do more research to help support your claims.
‘World’s first human clone born’
27 December 2002
A sect claims the world’s first cloned human - a girl - has been born.
The child was born by cesarean section and the birth “went very well,” said Brigitte
Boisselier, a French chemist and member of the Raelian sect. Boisselier called a news
conference in Florida to make the announcement and said she would have an
“independent inspector” take DNA evidence from the baby and her 30-year-old mother.
The Raelians, who claim 55,000 followers worldwide, believe that life on Earth was
established by extra-terrestrials who arrived in flying saucers 25,000 years ago, and
that humans themselves were created by cloning. Founder Claude Vorilhon, a former
French journalist and leader of the Raelians, says it is a commercial company which
wanted to make “as much money as possible”. But the long-term goal is to create
“eternal life through cloning”.
He told the Miami Herald that within 25 years the sect hope to develop technology to
create a full-grown human clone in only a few hours. The mind of the cloned adult
would receive instant knowledge via the “uploading” of information directly from the
brain of another person. Mr Vorilhon claims a space alien visiting him in 1973 revealed
that extraterrestrials had created all life on Earth through genetic engineering.
‘Wave of condemnation after clone claim ‘
29 December 2002
The leader of a religious sect that claimed to have created the first human clone called
the development ‘just the first step’ toward human immortality through cloning.
But the announcement was met with skepticism and concern, since other cloned
mammals have had serious birth defects or developed health problems.
Scientists, including one who leads a rival cloning project, condemned the claim, and
religious organizations are outraged.
“Without any scientific data, one has to be very, very skeptical,” said Dr Robert Lanza,
the head of medical and scientific development for the private research firm Advanced
Cell Technologies.
“This is a group that has no scientific track record, never published a single scientific
paper in this area,” Lanza said.
“They have no research experience in this area. In fact, they have never even cloned a
mouse or a rabbit.”
The announcement was also greeted with dismay in Australia, with stem cell
researcher Professor Alan Trounson describing the sect behind the human cloning as
being "from outer space".
He said the alleged cloning offered nothing to science and medicine.
“There is no scientific gain (that has) been linked scientifically to this group and there
has never been any confirmation of their claims," Professor Trounson said.
He also said the sect would need to demonstrate the exact likeness of the child to
another human.
‘Clone baby could be a hoax: investigator’
7 January 2003
US journalist Michael Guillen, who has been trying to verify claims a human clone baby
has been born, says the claims could be “an elaborate hoax” by the Raelian sect.
Mr Guillen says he has suspended the verification process, after Clonaid, a company
founded by the sect, claimed it had created the first human clone.
“This morning, I suspended the independent review process designed to determine
whether or not a cloned human baby has been born,” Mr Guillen said in a statement.
“The team of scientists has had no access to the alleged family and therefore cannot
verify first hand the claim that a human baby has been cloned. In other words, it's still
entirely possible Clonaid’s announcement is part of an elaborate hoax intended to bring
publicity to the Raelian movement,” he said.
Clonaid spokeswoman Nadine Gary says she is surprised by Guillen’s announcement
and that she was unaware of the suspension.
Questions:
Although all forms of cloning are illegal in Australia (and reproductive cloning is banned
in many countries) it is widely discussed in the media and in speculative fiction as a
possibility or reality. With this in mind:
• Do you believe the claim of a human clone having been born?
• What did the scientists have to say about the claim?
• How do you think the Raelians could have successfully cloned a healthy
human if scientists are having difficulty in achieving this with other mammals?
• Assuming that the claims are true:
o Is this fair on ‘Eve’, the cloned baby?
o How do you think ‘Eve’ would feel about being the first human clone?
o What happens if there are developmental or health problems? Who
would be responsible? Would ‘Eve’ have legal recourse?
o If ‘Eve’ had children in the normal way, what would it mean for her
children?
• What if a cloned person was cloned themselves? What does that mean for
their parentage?

Good Morning,
Something very odd happened a few days ago, which I would like you to research and give your thoughts about what might have happened. Thousands of birds have been falling from the sky, dead. Start with the following link to find information and then proceed to any aditional sites that might have information explaining this odd occurance. Do you think we should be worried?

Good Morning and Welcome Back! We will be wrapping up genetics this week and moving onto chemistry next week.
In your table groups I would like you to work together to choose a meal, perhaps one that you enjoy eating ( i.e.turkey, mashed potatoes, green beans, and a yummy roll) Make a list of all the ingredients that go into that meal and research to find if your foods from your meal are in any way genetically modified or altered. Describe what the ingredient is, how it is modified, and to what extent.
When you are finished please review the class calendar for what we have planned for the week ahead. Happy 2011!

As you research your genetic disease here is another disease I would like you to investigate, Prader-Willi Syndrome.
1.) How is this disease caused?
2.) What are the symptons of this disease?
3.) Are there any current treatments available? If so what and how does it work?
When you are finished go to you tube and look for videos on this disease to view.
