QUES: Renewable Energy Resource Sunlight Sunlight can be used to heat homes. It can also be used to produce electricity. This conversion is made possible by solar cells. However, solar energy may not always be practical. Some areas are just too cloudy. Example Solar panels on the roof of this house generate enough electricity to supply a familys needs. Moving Water Falling water can have a lot of energy. Its energy can be converted into kinetic energy. This energy can turn a turbine and generate electricity. The water may fall naturally over a waterfall or flow through a dam. A drawback of dams is that they flood land upstream. They can also reduce water flow downstream. Either effect may harm ecosystems. Wind Wind is moving air. It has kinetic energy that can do work. Wind turbines change the kinetic energy of the wind to electrical energy. Only certain areas of the world get enough steady wind. Many people also think that wind turbines are noisy and not very nice to look at.

QUES: Hannah Harvey was a ten year old that had many friends in school. She lived in New York and enjoyed doing gymnastics and playing soccer. One day, Hannah came home from school and her parents greeted her. She knew that something was different by the expressions on their faces. Even Jackson, Hannah's dog, was acting different. Hannah asked why everyone was being so strange. Hannah's father, who was known as Pop, explained to Hannah that his job was forcing him to move. Hannah did not seem to think this was too big of a deal. Then, Hannah's mother explained that they were moving to Kenya. Kenya, she explained, was a place in Africa and life would be very different there. As Hannah began to cry thinking about all of her friends at home, Hannah's mother calmed her with a gentle touch. Jackson began howling as Hannah cried, but was also calmed by Hannah's mother. Hannah spent the next two weeks visiting her friends and saying her goodbyes. She did not know the next time she would be home. She cried very hard when she said goodbye to her best friend, Susan. Susan did not quite understand where Kenya was, but promised to visit Hannah. The next day, Hannah boarded a plane with her family. At first, they thought that Jackson could not come with them. However, Hannah worked hard and helped make sure that he had all of his shots so that he could come. After he had them all, the airport said it was OK for Jackson to come! The Harvey family left and off they went across the ocean to begin their new life in Kenya.

QUES: As food is pushed along, it undergoes digestion. Digestion is the process of breaking down food into nutrients. There are two types of digestion: mechanical digestion and chemical digestion. Mechanical digestion occurs when large chunks are turned into smaller chucks. Perhaps not surprisingly, this happens when you chew your food. Once you swallow the food, your stomach also does some of this work. Chemical digestion occurs when food is broken down into useful nutrients. This is a chemical process that begins as you start to chew your food. The saliva in your mouth starts this process. Once you swallow, the acid in your stomach further breaks down food. From the stomach, the foods moves into the small intestine. In the small intestines, another set of chemicals goes to work. Are you surprised? Your small intestine, and not your stomach, does most of the work!
