Few cities have the human and natural diversity that Houston has. There is no need to go anywhere to learn about African, Hispanic or Asian cultures since Houston is extremely diverse, with people from different racial, ethnic and cultural backgrounds. In addition, Houston and the surrounding area are inhabited by many animals that have become a common sight for Houston's city dwellers. Since Houston is such a unique place, students can learn a lot about the world that surrounds them. The intention of this curriculum unit is to awake my third grade students' curiosity about "their neighbors," i.e., Houston's multicultural population and its flora and fauna that enrich and shape urban life. This unit combines two subjects: social studies and science. These subjects will be taught through an ESL (nglish as a Second Language) approach, as all of my students are LEP (Limited English Proficiency). In social studies the students will get familiarized with the city they live in using maps. They will also learn about Houston's ethnicities, their culture, traditions and festivals. In science they will learn about several wildflowers, vegetables and herbs planting them in the school garden. Besides, they will discover many interesting facts about some Houston birds. All the activities of this unit have been developed to improve one or several of the following skills: reading, listening, speaking and writing. After this unit, I would like my students to have developed a respect and value for the earth and its inhabitants.
