Interdisciplinary Science & ELA lesson for 5th grade

# data[].attributes.body
Cloning

# data[].attributes.body
The purpose of this lesson is to expose students to a new topic they might not have heard much about before. The other purpose is for students to use their critical reading skills to answer the discussion questions and also critically evaluate the sources.

# data[].attributes.body
In this portion, I will first explain to students how to critically analyze sources. I will also read the first source to students and model how I am analyzing the source. I will also highlight how I am finding the main ideas of the article.

# data[].attributes.body
In this portion, we will be looking through two sources together. We will work on filling out the provided google doc together as well for source 2.

Create a new document and edit with others at the same time -- from your computer, phone or tablet. Get stuff done with or without an internet connection. Use Docs to edit Word files. Free from Google.

# data[].attributes.body
In this portion, students will work on filling out the remaining information for source 3. Then, the students will get into groups and read through the fourth source together while filling out the information in the google doc for source four.

# data[].attributes.body
1. Analyzing Sources
2. Finding key ideas and details
3. Relating the key ideas and details back to answering the essential question

# data[].attributes.body
1. Teacher Modeling
2. Article explaining evaluating sources
3. The four online texts
4. The Google Doc

# data[].attributes.body
The main objectives for this lesson are for students to determine the main ideas of each article and also for students to analyze multiples sources. Also this lesson will enhance and deepen students' understanding of the content/instruction by giving them multiple chances to practice critically analyzing sources.

Time for Kids Article: "Reversing Extinction"

# data[].attributes.attachment_link.readable_text
Bringing back from extinction may seem more like science fiction than reality. But scientists are close to being able to bring animals back from the dead.

The first major breakthrough in de-extinction came just over 15 years ago. A team of Spanish researchers collected samples from the last living Pyrenean ibex, a beige mountain goat who was nicknamed Celia. They inserted Celia's preserved DNA, the chemical that carries the structure for a living thing, into the egg cells of a closely related species of goat. After an electric shock, the cells began to form .

Scientists then implanted the embryos into female goats. Only one of the embryos survived. But the newborn died in less than 10 minutes. As a result, the Pyrenean ibex is the only species to have gone extinct twice.

Celia's was short-lived. Yet it "showed that de-extinction is technically possible," biologist Helen Pilcher told TFK. And since the Celia experiment, scientific advances have given researchers new into restoring extinct species.

In an attempt to bring back the gastric-brooding frog, scientist Michael Archer is using a refined version of the techniques that were used to clone Celia.

The gastric-brooding frog went extinct in 1985. It was killed off by a disease spread by humans. Archer believes people have a "moral obligation " to restore animals that have gone extinct because of human activity. He produced embryos containing the extinct frog's DNA. But they only survived for a few days. Despite this setback, Archer is confident his team will overcome these "speed bumps on the way to success with de-extinction."

The Mammophant in the Room

Scientists have had some success restoring recently extinct animals. But attempts to bring back long-dead species have been less promising. That is because DNA decays over time.

Enter the woolly mammoth. These elephant-like beasts disappeared from Arctic regions about 4,000 years ago. Scientists have discovered their remains. But "mammoth DNA found in the wild is highly [damaged]," George Church says. He is the head of Harvard University's woolly mammoth revival project.

Church uses an advanced tool called CRISPR to insert DNA from a mammoth into the DNA of a close living relative: the Asian elephant. He hopes to refine this technique and produce an embryo in two years.

The result will be a mammophant. It will look like an elephant but will have mammoth-like features. These will include thick hair and blood that can tolerate cold weather.

Church hopes his efforts will restore an extinct species. His ultimate goal is to release herds of mammophants into the Arctic. His plans would also help save the endangered Asian elephant. Giving it the traits needed to survive in the Arctic would give the species another chance because it would be isolated from human populations.

Price of Progress

Restoring vanished species is within reach. But some experts say it could hurt endangered animals. "It is worse than worthless," Paul Ehrlich says. He is a biologist at Stanford University. He believes de-extinction is a "damaging waste of time and resources" that should be spent on protecting existing wildlife.

Other scientists, like Pilcher, argue that money for de-extinction and funding for conservation come from different sources. She adds that de-extinction science can be used to protect animals on the verge of disappearing. "These kinds of techniques offer these species a lifeline," she says. "It's not a case of if de-extinction will happen but when."

Newswer article: "Scientists Looking to Reverse Extinction

# data[].attributes.attachment_link.readable_text
(Newser) - Human activity and other factors have annihilated countless species over the last few hundred thousand years, but researchers now believe some of those creatures aren't necessarily gone forever, the New York Times finds. Cloning requires an intact cell, but advances in technology mean that it could be possible to bring back an extinct species by using genetic material to create hybrid cells to clone from a closely related species. Researchers using cloned cells have already tried to bring back the Pyrenean ibex, though the baby animal created survived just minutes. Efforts to bring back Australia's extinct Southern gastric brooding frog have so far yielded only embryos that failed to survive.

The efforts to reverse extinction raise many ethical questions, and it may not be desirable to bring back some species, including the huge flocks of passenger pigeons that used to carpet American cities in an inch-deep layer of guano, says the director of the Stanford Center for Law and Biosciences. But ethical questions aside, he is among many scientists who would love to see mammoths, saber-toothed tigers, and giant ground sloths roam the world once again. "We are not talking Jurassic Park," he says. "We are talking Pleistocene Park, 100,000 or 200,000 years ago," and "there are an awful lot of cool things that died within the past 200,000 years."
