QUES: Jenny was a 13 year old girl with blond hair and blue eyes. She had gotten out of her last day of school and was free for the summer. Two of her friends were going to the nearby beach to do some swimming and enjoy the sun. Jenny went with them and when they got there the beach was very full and there were people everywhere. They changed into their bathing suits and went to the water. The water was very cold. They chose not swim and walked to the sand. Then they laid down on some towels and enjoyed the sun. After several hours Jenny and her friends fell asleep. They woke up and the sun was beginning to set. When Jenny sat up she found that it was painful to touch her skin. When she looked down she saw that she had a very bad sunburn. Her friends were also very badly sunburned so they went home. Jenny's mother gave her a cream to put on the sunburn. Afterwards she felt a lot better and went to sleep.

MY QUESTION: Who was sun burned?

QUES: Earths magnetic field helps protect Earth and its organisms. It protects us from harmful particles given off by the sun. Most of the particles are attracted to the north and south magnetic poles. This is where Earths magnetic field is strongest. This is also where relatively few organisms live. Another benefit of Earths magnetic field is its use for navigation. People use compasses to detect Earths magnetic north pole. Knowing this helps them tell direction. Many animals have natural 'compasses' that work just as well. Birds like the garden warbler in Figure 1.36 use Earths magnetic field. They use it to guide their annual migrations. Recent research suggests that warblers and other migrating birds have structures in their eyes. These structures let them see Earths magnetic field as a visual pattern.

MY QUESTION: What works to detect Earth's magnetic north pole, telling direction besides people's compasses?

QUES: You might want to know how cold it is. You may need to know how fast the wind is blowing. Maybe it rained last night? Do you know how much? Does it feel humid to you? You have heard all these questions before. To answer these questions, we need data. That data comes from special tools. These tools collect data about the weather. You can see some of the common tools listed below: A thermometer measures temperature. An anemometer measures wind speed. A rain gauge measures the amount of rain. A hygrometer measures humidity. A wind vane shows wind direction. A snow gauge measures the amount of snow.

QUES: Our sun and other stars release light energy. At least this is what we see. Our Sun and stars also emit more than just light. Scientists call the type of energy that our Sun and stars release electromagnetic energy. This form of energy travels through space. Electromagnetic energy includes the light we see. It also includes much more. Many of these things we know about, but dont always think about. Electromagnetic energy includes radio waves, microwaves, and X rays. We now have devices in our homes and offices that release these same forms of energy. We use electromagnetic energy to make our lives better.
