Barb and Dee studied chemistry for a school project. After little debate they decided that Dee will study volatile gases, and Barb will study greenhouse gasses. Given the paragraph above, please answer correctly the following question: Which girl studied less about methane? Hint: Greenhouse Effect: The solar energy reaching the surface of the Earth is concentrated in short wavelengths, which can easily penetrate the greenhouse gases, such as carbon dioxide and methane. The Earth, however, is cooler than the sun and it radiates its heat in the form of energy in the far infrared range. These longer wavelengths are partially absorbed by the greenhouse gases and some of the solar heat is returned to Earth. At a certain temperature these processes are in equilibrium and the surface temperature of the Earth is stable. However, if more greenhouse gases are put in the atmosphere the amount of trapped terrestrial radiation increases, leading to an increase in global temperature.
Ans: Dee

Michael wants to play a trick on his friend. He takes a bottle of soda, shakes it really well then puts it in the fridge. He then tells his friend if he wants something to drink there's some soda in the fridge. Michael's friend goes to the fridge and pulls out the bottle Michael just shook and opens it. Given the paragraph above, please answer correctly the following question: Which has higher kinetic energy, carbon dioxide in a cola solution at rest, or in a shaken state? Hint: A: You could shake a bottle of cola and then open it. Shaking causes carbon dioxide to come out of the cola solution and change to a gas. The gas fizzes out of the bottle and spreads into the surrounding air, showing that its particles have enough kinetic energy to spread apart. Then you could tilt the open bottle and pour out a small amount of the cola on a table, where it will form a puddle. This shows that particles of the liquid have enough kinetic energy to slide over each other but not enough to pull apart completely. If you do nothing to the solid glass of the cola bottle, it will remain the same size and shape. Its particles do not have enough energy to move apart or even to slide over each other.
Ans: shaken

Manny and Dean were two classmates. They had to prepare for a school project so they decided to learn about animals. Manny studied animal communication, while Dean studied animal feeding patterns and nutrition. Given the paragraph above, please answer correctly the following question: Which student didn't learn about the ability of animal group members to avoid conflict? Hint: Communication is any way that animals share information. Many animals live in social groups. For these animals, being able to communicate is essential. Communicating increases the ability of group members to cooperate and avoid conflict. Communication may help animals work together to find food and defend themselves from predators. It also helps them find mates and care for their offspring. In addition, communication helps adult animals teach the next generation learned behaviors. Therefore, communication generally improves the chances of animals surviving and reproducing.
Ans: Dean

Two counties were part of the same region. Green county used alternative methods to produce energy, while Brown county used fossil fuels and released a lot of carbon dioxide into the atmosphere. Given the paragraph above, please answer correctly the following question: Which county caused more ocean acidification? Hint: Carbon dioxide is the most significant long-lived greenhouse gas in Earth's atmosphere. Since the Industrial Revolution anthropogenic emissions primarily from use of fossil fuels and deforestation have rapidly increased its concentration in the atmosphere, leading to global warming. Carbon dioxide also causes ocean acidification because it dissolves in water to form carbonic acid.
Ans: Brown
