You couldnt survive without your skin. It has many important functions. The main function of the skin is controlling what enters and leaves the body. It prevents the loss of too much water from the body. It also prevents bacteria and other microorganisms from entering the body. The skin helps maintain a constant body temperature. It keeps the body cool in two ways. Sweat from sweat glands in the skin evaporates to cool the body. Blood vessels in the skin dilate, or widen. This action increases blood flow to the body surface. This allows more heat to reach the surface. The heat is then able to radiate off the body. The opposite happens to retain body heat. Blood vessels in the skin constrict, or narrow. This decreases blood flow to the body surface. This reduces the amount of heat that reaches the surface. When this happens, less heat can be lost to the air. <sep>What prevents the loss of too much water from the body?<sep>Glands
No

What causes a change in motion? The application of a force. Any time an object changes motion, a force has been applied. In what ways can this happen? Force can cause an object at rest to start moving. Forces can cause objects to speed up or slow down. Forces can cause a moving object to stop. Forces can also cause a change in direction. In short, forces cause changes in motion. The moving object may change its speed, its direction, or both. We know that changes in motion require a force. We know that the size of the force determines the change in motion. How much an objects motion changes when a force is applied depends on two things. It depends on the strength of the force. It also depends on the objects mass. Think about some simple tasks you may regularly do. You may pick up a baseball. This requires only a very small force. <sep>Does an object's mass has very little to do affect how much its motion changes when a force is applied to it?<sep>No
No

Jake was walking to the park to play baseball with his friends. He loved being outside on sunny days, and now that school was over for the year, he was playing baseball every day. The more he played, the better he got. Only Frank was better than he was. He liked playing third base, but he often played in the field. He was carrying his favorite mitt that his Grandfather had bought him. His Grandfather had taught him to catch. He loved spending time with him when he was younger, but he had moved last year. Now he only saw his Grandfather in the summer. Jake was really excited to show him his skills when he came to their next game. He could throw really fast now. He was sure his Grandfather would want to sit in the front to watch him. He knew he would jump up and down. Jake happily ran the rest of the way to the park thinking about how much fun he was going to have playing baseball this year. <sep>Where did Jake go to on this sunny day?<sep>To the school
No
