Input: Consider Input: (CNN Student News) -- Students will make educated predictions about how many electoral votes each presidential candidate will capture in the 2008 U.S. presidential election. Procedure . Have students review the origin, purpose and function of the Electoral College. Ask students: What is the "winner take all" system? Are there any states that do not follow this system? If so, how do they determine their electoral vote allocation? How many electoral votes are needed to win the presidency? Next, divide students into small groups and assign each group a current swing state in the 2008 presidential race. Consult the CNN Electoral Map Calculator for a list of swing states. Then, refer groups to online resources, including CNN's Election Center 2008 on the CNN Politics site, to identify the following for their assigned swing state: . After students complete their research, have each group analyze its data to determine which candidate it thinks will likely capture the swing state's electoral votes. Have each group present its prediction and the rationale behind it. Following the presentations, direct students to the CNN Electoral Map Calculator to log their predictions for all the U.S. states and calculate how many electoral votes they predict each presidential candidate will capture. Instruct students to create a chart and log their predictions for each U.S. state. After the election, compare students' predictions to the actual electoral vote outcome. Wrap up the activity by discussing the role of the Electoral College in determining the outcome of a U.S. presidential election. Correlated Standards . Civics . 9-12 Content Standards . II.

Input: Consider Input: The ancient world was full of strange animals that have gone extinct, such as a group of marine species with claw-like structures emerging from their heads. A new study suggests that these creatures were related to spiders and scorpions. Researchers discovered the fossilized remains of a species in southwest China that provides new insights into the evolution of animals in the modern era, scientists said. They report their findings in the journal Nature. Scientists believe that the creature -- 1 inch long, and with two pairs of eyes -- lived 520 million years ago and that it crawled or swam in the ocean. They were able to reconstruct the creature's nervous system to gain insights about its evolutionary relationships to animals familiar to us. "For the first time, we are able to use fossilised neural anatomy to sort out how fossil animals are related to animals today," study co-author Xiaoya Ma of the Department of Earth Sciences at the Natural History Museum in London wrote in an e-mail. This creature belongs to the Alalcomenaeus genus, and its place in the animal kingdom lies in "a group of weird extinct animals" called the "megacheiran" or "great appendage" arthropods, Ma said. The species of the Alalcomenaeus group had elongated, segmented bodies with about 12 pairs of appendages they used for swimming or crawling. They also had a pair of long, scissor-like head claws, most likely for grabbing or sensing. Scientists say the reconstruction of the new creature's nervous system is the most complete for an arthropod living at that time, in the Cambrian geological period. Discovery makes a splash: The rarest whale . The brain and central nervous system of the creature are organized in a way that is similar to those of the chelicerata, the group that includes horseshoe crabs and scorpions. This suggests a close evolutionary relationship between the ancient Alalcomenaeus and the living chelicerata. A distinct group of arthropods called the mandibulates includes lobsters, insects, centipedes and millipedes. Last year at the same site in China -- called the Chengjiang formation near Kunming -- Ma and colleagues discovered a 520 million-year-old crustacean-type nervous system in an animal called Fuxianhuia. Taken together, these discoveries suggest that by 520 million years ago, the two major groups of arthropods had diverged. Their common ancestor must have been older, researchers said. "This means the ancestors of spiders and their kin lived side by side with the ancestors of crustaceans," co-author Nick Strausfeld, neuroscience professor at the University of Arizona, said in a statement. Strausfeld's team used sophisticated imaging techniques to look at the inch-long Alalcomenaeus fossil. One kind of scan revealed that iron had built up in the nervous system as the creature fossilized. They also used a technique called computed tomography that reconstructs 3-D features. By combining these images and discarding any data that weren't in both, they were able to create a sort of negative X-ray photograph, "and out popped this beautiful nervous system in startling detail,"  Strausfeld said. It confirmed what scientists had believed from the creature's outward appearance: The extinct genus Alalcomenaeus was related to chelicerates (spiders, scorpions and others). They also saw that the brain in the fossil was like the brains found in modern scorpions and spiders. If researchers find a fossil with features shared by this creature and the crustacean-like fossil Ma and colleagues found last year, that could be a common ancestor of both. There's plenty more weirdness from ancient history to uncover. 18-foot oarfish discovered .

Input: Consider Input: London (CNN) -- London's Heathrow Airport is "fully operational" and returning to normal after an emergency landing Friday forced the closing of both runways, the airport said -- but many travelers are likely to suffer delays anyway. British Airways has canceled all its inbound and outbound short-haul flights until 4 p.m. (11 a.m. ET) as a result of the incident. And Heathrow Airport has warned of disruption to travel that could last all day. So far, 23 planes have been diverted to other airports and 19 flights canceled, some arrivals and some departures, a spokeswoman said Friday morning. The airport is working to return to normal service as soon as possible, she said, but passengers are advised to check with their airlines. A British Airways plane bound for Oslo was forced to make the emergency landing "due to a technical fault," the airline said. Flight BA762 turned back less than half an hour after taking off for the Norwegian capital, it said. The Airbus A319 aircraft was carrying 75 passengers and five crew members, the airline said. The passengers were evacuated from the plane on emergency slides. "Airline colleagues are now caring for customers in the airport terminal," said British Airways. London Ambulance Service treated three patients for minor injuries after the emergency landing, it said on Twitter. British Airways said it would be carrying out a full investigation into the incident, alongside the Air Accident Investigation Branch, part of the UK Department for Transport. The slides were deployed on the left side of the aircraft, indicating that the problem was with the right engine, said CNN's Richard Quest. Planes can fly safely even if only one engine is operational, he said. London Fire Brigade said one of its crews helped the airport fire service put out an aircraft fire. "We believe the fire is now out," it said via Twitter. Heathrow, which is a major international hub, was ranked the third busiest airport in the world in 2012 after Atlanta and Beijing, according to Airports Council International. Monday is a holiday in the United Kingdom, so many people will be taking flights Friday to take advantage of the long weekend. Holidaymaker Aileen Wilson was one of many travelers whose flight was grounded by the incident. "We've just been sitting, waiting in a plane meant to take off" this morning, she told CNN iReport. "At first we were told ongoing incident and then emergency landing. We (are) still waiting to take off (and) not allowed out of plane!" Instagram user Shazia Shaikh took a photograph from the office where she works at Heathrow Airport of emergency vehicles surrounding a plane. "Runways closed (and) lots of smoke," she told CNN iReport. "The rain doesn't help. Emergency vehicles were quick to the aircraft I'm told." On average, 190,000 passengers travel through the airport each day, half arriving and half departing, according to Heathrow's website. CNN's Claudia Rebaza, Richard Allen Greene, Sarah Brown and Dominique Van Heerden contributed to this report.
