QUES: Have you are burned something on the stove or in the oven? Do you know why things burn? It all has to do with temperature. Changes in matter are affected by temperature. For example, what if you place a cake in the oven and you leave it in too long? What do you think will happen? Thats right, it will probably burn. The same thing will happen if the oven setting is too high and you apply too much heat. In either case, heat has affected the rate of change in matter. Its probably obvious that when the temperature is increased a chemical change, like cooking, will occur faster. What about a physical change? Are physical changes affected by temperature? Most of us have seen steam rising off a wet road after a summer rainstorm. This happens because the road surface is very warm. The warm road and warm air temperature causes the water to evaporate quickly. The liquid water is turning into water vapor, but it is still water. The evaporation of water is a physical change. So yes, temperature affects the rate that physical change occurs.

QUES: Charlie Mershone had no difficulty in securing his release when Parker came on duty at six o'clock. He called up a cab and went at once to his rooms at the Bruxtelle; and Fogerty followed him. While he discarded his dress-coat, took a bath and donned his walking suit Mershone was in a brown study. Hours ago Louise had been safely landed at the East Orange house and placed in the care of old Madame Cerise, who would guard her like an ogre. There was no immediate need of his hastening after her, and his arrest and the discovery of half his plot had seriously disturbed him. This young man was no novice in intrigue, nor even in crime. Arguing from his own stand-point he realized that the friends of Louise were by this time using every endeavor to locate her. They would not succeed in this, he was positive. His plot had been so audacious and all clews so cleverly destroyed or covered up that the most skillful detective, knowing he had abducted the girl; would be completely baffled in an attempt to find her.

QUES: It is not enough to describe some objects by their location. We may also need to know its direction. For example, a wind blows a storm over your school. Where is that storm coming from? Where is it going? How can we describe a direction? The most common way is by using a compass. A compass is a device with a floating needle (Figure 2.1). The needle is a small magnet. The needle aligns itself with the Earth's magnetic field. The compass needle always points to magnetic north. If you have a compass and you find north. You can then know any other direction. See the directions, such as east, south, west, etc., on a compass rose. The Earth has two poles. It has a magnetic north pole. It also has a geographic north pole. These two poles are close to each other but not the exact same place.

QUES: For thousands of years, people have found fossils. The fossils caused curiosity about Earths past. How did these organisms live? What type of world did they live in? Fossils can tell us a lot about Earths history. In ancient times, fossils inspired myths and stories. These stories included tales of monsters and other incredible creatures. What type of creature do you know that could inspire such stories? Of course, dinosaur fossils were once mistaken for dragons bones. Two thousand years ago, people discovered fossils in China. At the time, they were thought to be dragon bones. We know now that these were not bones, but fossils. So what is the difference?
