Science literacy for all students is an education goal in the United States, as well as in many other parts of the world. Habits of mind are the skills and attitudes that students need to develop in order to understand science as a way of thinking. In this standards-based era, habits of mind can be readily incorporated to teach multiple content areas, in the natural sciences as well as in integrated settings. The authors' purpose in designing this unit was to develop habits of mind in middle school learners. Throughout this unit, habits of mind standards are stressed as a way to increase science literacy, specifically, nutritional literacy, in middle school learners. (Contains 1 figure and 1 resource.)
