[Music] this is the kind of day Rob had been waiting for a chance to go fishing with Uncle Mac it looks as if Rob may have something there yes sir he's got one a beauty must be8 maybe 9 lb Rob can't wait to show his fish to Kathy she's picking berries with Mother near [Applause] Camp with Rob's fish and all those berries it looks as if the family has a good dinner coming up Dad is pleased with with Rob's catch Rob has an idea he will cook the fish he can get the dinner all by himself and surprise mother what else should they have Rob thinks hard well they could have raspberries his favorite and soda pop and cookies and cake and jelly roll and lollipops and ice cream and and raspberries his favorite of all whoo says Dad tell that to Uncle Mac when you get me some gasoline Uncle Mack explains that just as people need food Motors need fuel gasoline for energy and oil to keep the parts from wearing out but they need just the right amount of each to run well Rob begins to understand how people need fuel too Rob wonders what is the best fuel for people if Rob could look closely enough he'd see that the body is made of many many tiny Parts called cells there are different kinds of cells and the cells need different kinds of materials to grow and do their jobs nerve cells need one kind of material to help them send signals muscle cells need materials that give them energy to move the materials that all your different cells need to do their jobs are prepared by your digestive system from the food you eat first the food in your mouth is chewed here it is ground into small pieces and mixed with saliva when you swallow food passes down a tube to the stomach here it is mixed with special fluids which help break down the food into finer particles then it goes to the small intestine if you could see the lining of the small intestine you'd see that the food particles are very small so small they can pass through the wall of the small intestine and enter tiny blood vessels called capillaries now the blood carries food to the many different cells of the body in this way nerve cells get energy to send signals and muscle cells get energy to do their work so when Rob plans his supper he asks dad to help him choose the right foods that the body needs for fuel some foods such as fresh fruits and vegetables give you vitamins and minerals but all foods give you the materials you need for growing and for energy sweet foods and foods made from flour give you quick energy so do potatoes fats and oils give you energy too and help to keep you warm eggs meat and cheese are used by your body mainly for growing and repair these foods are called proteins fish is a fine protein food which foods will rob choose for quick energy there are other important foods too some contain minerals that help build strong bones and teeth and the foods which contain minerals usually have vitamins too some vitamins help keep the eyes healthy others are good for blood and blood vessels and still others keep the nerves working properly as they wash before dinner Rob tells Kathy about his surprise for mother and mother is surprised she is pleased that Rob has planned such a good meal Rob has the fish a fine protein food and Kathy brings the bread for quick energy the salad and juice and milk have minerals and vitamins building foods and energy foods Rob has thought of all the foods the body needs because Rob has planned his dinner so well mother announces a surprise of her own for dessert Rob's favorite all the raspberries he can eat when Rob and Kathy plan a different meal what should they have besides raspberries [Applause] [Music]
