For this activity it is probably a good idea to use with either talking about different dinosaurs but better yet cloning and how it works. Students will need a basic knowledge base however could be used as a introductory activity from which students would spend more time doing research and defining vocabulary. Students will need to know different dinosaurs or will have to look them up as well as the eras. If using this to studied the different eras the question about which dinosaur could be rephrased as “if you could clone something what would is be and from what era would it come from?” Teachers will need a understanding of how cloning works how dolly was cloned and what terminator genes are and information about reptiles and adaptations that can occur in them. This activity can be used for a revive of cloning and views about it. Insert paragraph text here.

Objectives
, to spark critical thinking skills, public speaking, research skills, reasoning out, pros and cons of cloning
Assessment
would be arguments formed in a paper format based on research and performance
Can work by themselves or in groups I would recommend groups at last part of it. At the end students would form their arguments in the form of a short paper and hold a debate. Insert paragraph text here.
Students will need access to a dictionary or text to look up words and most likely a computer to do research. Students also need paper and writing utensils and some form of coloring utensils to draw out there dinosaurs.Insert paragraph text here.
Dinosaurs that lived in the Jurassic period lived from 199.6 millions years ago to145.5 million years ago. The Jurassic period was in the middle of the Mesozoic era and was also know as the Age of Reptiles. It is thought that large dinosaurs were the dominant type during the Jurassic period. Mainly the herbivorous dinosaurs know as the sauropods like the Diplodocus and Brachiosaururus which ate ferns and coniferous growth which were then prayed upon by the carnivorous dinosaurs like the Megalosaurus and the Torvosaurus which belongs to the saurischian branch. Also at the end of the Jurassic period it is thought that birds and smaller dinosaurs began to appear.Insert paragraph text here.

There are different types of cloning .Insert paragraph text here.
1) DNA cloning, = also referred to as molecular cloning or gene cloning it is the transfer of a DNA fragment from one organism to a self replicating genetic element like a bacterial plasmid then it can be taken and added to something and then you have a mixture of the two organisms
2) Reproductive cloning = used to generate an animal usually by a process of somatic cell nuclear transfer this is where scientists transfer genetic material from the nucleus of a donor adult cell to an egg whose nucleus has been removed
3) therapeutic cloning = is also called embryo cloning is used to harvest stem cells.
So what have scientist cloned tadpoles, mice, rabbits, goats, sheep, cows, pigs, and a gaur.
(Cloning Fact sheet, 2008)
There is even an attempt to clone the baby mammoth found in Russia in 2007
They have also started to clone endangered species and extinct species.
“The San Diego Zoo and the Audubon Center for Research of Endangered Species in New Orleans both maintain "frozen zoos," where the DNA of a growing number of endangered species is stored in tanks of liquid nitrogen at minus 320° Fahrenheit. In 2003 scientists at Advanced Cell Technology used cells stored at the San Diego facility to success
fully clone across the species barrier. They created two bantengs, an endangered Southeast Asian ox, by inserting banteng DNA into domestic cow eggs and placing the resulting embryos in cow foster-mothers. There is talk of using similar methods to clone endangered giant pandas, African bongo antelopes, and Sumatran tigers. Ultimately scientists hope to re-create extinct species like the Pyrenean ibex and the thylacine, or Tasmanian tiger.”
(Cloned Species, 2009)
“In late November a humble Iowa cow is slated to give birth to the world's first cloned endangered species, a baby bull to be named Noah. Noah is a gaur: a member of a species of large oxlike animals that are now rare in their homelands of India, Indochina and southeast Asia.”

Have you ever watched Jurassic park? Well I Dr. Zanie Labnose, say cloning dinosaurs is coming really soon I have been working on it for years some would say that it is my life’s work. The press caught hold of my research and have been bothersome ever since, can you believe they gave out my address I have been getting fan and hate mail since. I don’t understand who wouldn’t want there very own dinosaur.
Science has progressed an incredible amount Scientist have cloned pigs, mice, cows, tadpoles, goats and sheep. Just in the last three years have they cloned a guar a endangered species and are trying to clone other endangered and extinct animals. Did you know that they are working on cloning a baby mammoth that was found in Russia in 2007.With all this who can not agree that I the great Dr. Zanie Labnose can’t clone a dinosaur, all I have to do is find a remain in the fossils to pull out enough DNA. Right?
Here is my plan I will clone the females and then they can not repopulate and the connivers will be caged. Just imagine what we could de with dinosaurs they would make great weapons against other countries, they could be a great food source too. With the help of dinosaurs we could rule the world and do things the way we want them.

I been on archeological digs for years and recently found some bones from 185millon years to 160millon years based on carbon dating. Femur is as tall as me and as wide as my thigh I really think I can extract some DNA and then use frogs to colon the dinosaurs. What an awesome idea. SO why do people hate it so much. I mean it would be a scientific break through I might even get the noble prize not only that if this is successful just think what we can do afterwards. We could grow human organs no one would have to die because of organ transplants or of things like cancer, we could clone all the animals that have ever went extinct think of the power that we could have. I just don’t understand those awful people that hate me they say it’s a bad idea but I promise the dinosaurs will have terminator genes in them just like the food we eat and I will design them all to be girls so even if the terminator gene doesn’t work they still can not produce. I just think that science should not be held back by peoples consciousness and negativity science is science and it must go on with no boundaries.
1)Pick out key phrases that you agree with or disagree with.
2) Underline an vocabulary that you do not know and look up the definition.
3) As a scientist which dinosaur would you want to clone and raise and from which era would it be from? Please draw and label your dinosaur either individually or as a group, please include habitat scientific name interaction with others and food source.
4) Explain the cloning process.
5) Explain how it was possible to colon dolly? How and why is this different or alike when cloning something that’s been extinct?
6) Why would it matter or not matter if the dinosaurs had terminator genes or were all females, what issues can arise from this?
7) As science progresses to this type of capability what would be some of the pros and cons and other ethical issues that would arise with cloning dinosaurs, or cloning anything? Do some research in your groups and come up with a couple good ideas, you will be arguing against the Dr. Zanie Labnose scientist or with him so have ideas for both sides! Also be able to explain why you would write either a fan letter or a hate letter.
