Reading Process Paragraphs

     In the human body, the digestive system breaks down food so that it can be used for energy.  As food enters the mouth, chewing along with enzymes in the saliva, break it down into small pieces.  Next the esophagus contracts and pushes the food into the stomach where muscles, enzymes, and digestive acids turn the food into a thick liquid.  That liquid is emptied into the small intestine where most of its nutrients are absorbed.  What remains travels to the large intestine where water is removed from the digested food and turned into waste.  






PRACTICE:  Read the following paragraph and create a flow chart on a separate sheet of paper.  

     Cloud seeding is a a process state governments and private businesses use to increase the amount of snow or rain falling in a particular area.  The process begins with meteorologists who use radar, satellites, and weather stations to track storm fronts.  Next, they measure storm clouds for temperature, wind and composition.  When the meteorologists determine that cloud conditions are right, pilots seed the clouds with dry ice.  Seeding involves an aircraft flying above the clouds and dropping dry ice pellets directly into them.  Almost immediately, the dry ice begins attracting the clouds' moisture, which freezes to the dry ice's crystalline structure.  Finally, precipitation drops from the clouds to the earth in the form of rain or snow.
