Unit Objectives

  • Essential Concepts: 

    Reducing resource use and reusing/recycling resources is good for the environment.

    *Sample Questions:

    • Why does it matter how we dispose of waste?
    • How do reducing, reusing and recycling help the environment?
    • How can we do a better job of reducing, reusing, and recycling resources?
    • How can we encourage others to reduce, reuse and recycle?


    • ¿Por qué importa cómo nos deshacemos de los desechos?
    • ¿Cómo ayuda al medio ambiente la reducción, la reutilización y el reciclaje?
    • ¿Qué podemos hacer para mejorar el reducir, reutilizar y reciclar recursos?
    • ¿Cómo podemos animar a otros a que reduzcan, reutilicen y reciclen?

    *Note: Questions should be student-generated (formulated with teacher/librarian guidance). Guide students to personalize their questions and to encompass curriculum objectives.

    English Language Arts / Reading TEKS

    (24) Research/Research Plan. Students ask open-ended research questions and develop a plan for answering them.

    (A)  generate a list of topics of class-wide interest and formulate open-ended questions about one or two of the topics; and

    (B)  decide what sources of information might be relevant to answer these questions.

    (25) Research/Gathering Sources. Students determine, locate, and explore the full range of relevant sources addressing a research question and systematically record the information they gather. Students are expected to:

    (A)  gather evidence from available sources (natural and personal) as well as from interviews with local experts;

    (C)  record basic information in simple visual formats.

    (26) Research/Synthesizing Information. Students clarify research questions and evaluate and synthesize collected information. Students are expected to revise the topic as a result of answers to initial research questions.

    (27) Research/Organizing and Presenting Ideas. Students organize and present their ideas and information according to the purpose of the research and their audience. Students (with adult assistance) are expected to create a visual display or dramatization to convey the results of the research.
