February is Children's Dental Health month, but any time of year is appropriate for this unit, which includes a reading comprehension, and several science experiments perfectly designed to get children interested in the health of these "visible bones".
Three reading comprehension selections (Your Immune System, Immune System Disease, Keeping Your Immune System Healthy) clearly and simply explain how the immune system works and how to keep it working. Each selection is followed by 5 multiple choice questions and 4 questions that require brief written responses. (11 pages)
Three reading comprehensions (Your Respiratory System, Diseases of the Respiratory System, Take Care of your Respiratory System) clearly and simply explain how the respiratory system works and how to keep it working.
This unit is a great enhancement to a nutrition lesson, and also works well as a "stand alone". Based on the 2005 food pyramid guide, and featuring imaginative writing prompts, real-life nutrition analysis, graphing, and more.
