BEFORE READING Set a Purpose Read a fictional science mystery involving the corrosion of copper. Then perform the experiment and use deductive reasoning to solve the mystery. Background • Until 1982, a penny was made mainly of copper. After copper prices dramatically increased, the penny’s composition was changed to 97.5 percent zinc and 2.5 percent copper. Discussion Question • What color is the Statue of Liberty? Can you guess what the outside is made of? (Answer: The outside of the statue is made of copper.) AFTER READING Conclusion When a strong acid is poured over copper, it causes a chemical reaction. Milk contains a weak acid called lactic acid. Vegetable oil and orange juice contain different amounts of citric acid. Neither citric acid nor lactic acid is strong enough to cause copper to react. Vinegar, however, contains a very strong acid called acetic acid. This acid will react with copper, turning it green. So who ruined Ethan’s penny? Tyler did. He is the one who brought vinegar to school. Discussion Question • Why do you think the guilty person wanted to ruin Ethan’s penny? (Possible answer: He or she thinks Ethan is a know-it-all and is jealous of his spelling skills.) BEFORE READING Set a Purpose Background • The human brain weighs about three pounds. It’s made up of cells, called neurons, that form an immensely complex network. Communication between neurons is the basis of all brain function. • Neurotransmitters are chemicals that enable communication between neurons. • Neurotransmitters, either alone or in combination with others, can influence different emotional states. • Basic emotions, such as fear, anger, and attachment, are all processed in the brain and are expressed similarly in all mammals. Discussion Question • Why do you think it could be important for scientists to understand what happens in the brain when we are in love? (Answers will vary, but can include: It could help scientists treat people with emotional problems due to a brain injury or trauma; it could help scientists understand why some relationships are lasting and others are temporary.) AFTER READING Discussion Question • Do you think it would be ethical to sell a love potion-like drug that could artificially boost a person’s romantic feelings toward another person? Why or why not? (Answers will vary.)

To learn how teaching robots work and why they are being used in some classrooms. Set a Purpose Background • Hurricanes are very large circular storms that swirl around a calm, middle area called an “eye.” An average hurricane measures about 482 kilometers (300 miles) across—that’s greater than the width of the state of Georgia! • Hurricanes can dump up to 2 meters (6 feet) of rain in a single day. Wild winds blow at least 119 kilometers (74 miles) per hour. • Storms that form in the Atlantic Ocean are called hurricanes, while those that form in the western Pacific Ocean are called typhoons. Storms that form in the Indian Ocean are known as cyclones. Discussion Question • Do you ever check the weather forecast? If so, why? (Possible answers: So you know to carry an umbrella in case of rain; so you can decide how to dress appropriately for the weather; so you can stay indoors if the weather is going to be dangerous.) AFTER READING Discussion Question • Why do you think it’s important to give people information about a hurricane’s strength and the direction in which it’s traveling? (Possible answers: People can prepare by gathering supplies and protecting their homes; evacuation orders can be made in the case of strong storms in vulnerable areas; people can have time to leave an area if they have to evacuate.) RESOURCes • Hurricane Force: In the Path of America’s Deadliest Storms by Joseph B. Treaster. (Kingfisher, 2007). • For more information on hurricane-hunting scientists, visit this site: http://www.fema.gov/kids /huhunt.htm • For hurricane basics, check out: http://teacher. scholastic.com/activities/wwatch/hurricanes Set a Purpose Background • Highly programmed teaching robots are already serving as teachers’ aides in South Korea and Japan. They’re designed to teach students different languages, including English. Robots are also being created specifically to work with children who have special learning needs, such as those with Asperger’s syndrome. Some experts feel robots are well-suited for this task because they are infinitely “patient” and can perform repetitive therapies tirelessly. • To perform social interactions, teaching robots are guided by artificial intelligence software that allows them to be fully autonomous. • To recognize whether a child is smiling, RUBI analyzes his or her facial expression. It can compare expressions against a database of 70,000 faces. Discussion Question • What are some robots you have used, seen, or heard about in the news? What are some jobs those robots perform? (Answers will vary.) AFTER READING Discussion Question • What would be some pros and cons of using robots in the classroom? What are the pros and cons of using robots to replace humans in certain jobs? (Answers will vary.) • If you were to invent a new robot, what kind of function would it perform? What would it look like? What would be its name? (Answers will vary.) RESOURCEs • Robot (DK Eyewitness) by Roger Bridgman. (DK Children, 2004). • Robots by Cliff Gifford, illustrated by Frank Picini.
