1. Elements and their combinations account for all the varied types of matter in the world. As a basis for understanding this concept:
 

• a. Students know that during chemical reactions the atoms in the reactants rearrange to form products with different properties.
• b. Students know all matter is made of atoms, which may combine to form molecules.
• c. Students know metals have properties in common, such as high electrical and thermal conductivity. Some metals, such as aluminum (Al), iron (Fe), nickel (Ni), copper (Cu), silver (Ag), and gold (Au), are pure elements; others, such as steel and brass, are composed of a combination of elemental metals.
• d. Students know that each element is made of one kind of atom and that the elements are organized in the periodic table by their chemical properties.
• e. Students know scientists have developed instruments that can create discrete images of atoms and molecules that show that the atoms and molecules often occur in well-ordered arrays.
• f. Students know differences in chemical and physical properties of substances are used to separate mixtures and identify compounds.
• g. Students know properties of solid, liquid, and gaseous substances, such as sugar (C6H12O6), water (H2O), helium (He), oxygen (O2), nitrogen (N2), and carbon dioxide (CO2).
• g. Students know properties of solid, liquid, and gaseous substances, such as sugar (C6H12O6), water (H2O), helium (He), oxygen (O2), nitrogen (N2), and carbon dioxide (CO2). 
• h. Students know living organisms and most materials are composed of just a few elements.
• i. Students know the common properties of salts, such as sodium chloride (NaCl).

PROPERTIES AND CHANGES OF PROPERTIES IN MATTER 
 

• A substance has characteristic properties, such as density, a boiling point, and solubility, all of which are independent of the amount of the sample. A mixture of substances often can be separated into the original substances using one or more of the characteristic properties. 
•  Substances react chemically in characteristic ways with other substances to form new substances (compounds) with different characteristic properties.  In chemical reactions, the total mass is conserved. Substances often are placed in categories or groups if they react in similar ways; metals is an example of such a group. 
• Chemical elements do not break down during normal laboratory reactions involving such treatments as heating, exposure to electric current, or reaction with acids. There are more than 100 known elements that combine in a multitude of ways to produce compounds, which account for the living and nonliving substances that we encounter. 

        1. The students will Create multiple-paragraph expository compositions:
           a. Establish a topic, important ideas, or events in sequence or chronological order.
           b. Provide details and transitional expressions that link one paragraph to another in a clear
               line of  thought.
           c. Offer a concluding paragraph that summarizes important ideas and details.
             (California Language Arts-Writing Standards 1.1.2) < http://www.cde.ca.gov/standards/reading/grade5.html >

        RESEARCH AND TECHNOLOGY OBJECTIVES:
        1 The students will use organizational features of printed text (e.g., citations, end notes,
        bibliographic references) to locate relevant information. 
        2. The students will create simple documents by using electronic media and employing organizational
        features (e.g., passwords, entry and pull-down menus, word searches, the thesaurusp spell check)

        (In addition to those included in the current California State Language Arts Framework)

        1.The students will use Power Point to create a presentation
        2.The students will create a simple publication using Microsoft Publisher.
        3.The students  will create a simple web page using Microsoft Word and/or Netscape Composer 4.6 or 4.7
        4.The students will write a narrative essay on what they learned doing this activity using Microsoft Word.

The technology foundation standards for students are divided into six broad categories. Standards within each category are to be introduced, reinforced, and mastered by students. These categories provide a framework for linking performance indicators within the Profiles for Technology Literate Students to the standards. Teachers can use these standards and profiles as guidelines for planning technology-based activities in which students achieve success in learning, communication, and life skills. 

    Technology Foundation Standards for Students 

      1.Basic operations and concepts 

• Students demonstrate a sound understanding of the nature and operation of technology systems. 
• Students are proficient in the use of technology. 

      2.Social, ethical, and human issues

• Students understand the ethical, cultural, and societal issues related to technology.
• Students practice responsible use of technology systems, information, and software.
• Students develop positive attitudes toward technology uses that support lifelong learning, collaboration, personal pursuits, and              productivity. 

      3.Technology productivity tools 

• Students use technology tools to enhance learning, increase productivity, and promote creativity. 
• Students use productivity tools to collaborate in constructing technology-enhanced models, prepare publications, and produce             other creative works. 

      4.Technology communications tools 

• Students use telecommunications to collaborate, publish, and interact with peers, experts, and other audiences. 
• Students use a variety of media and formats to communicate information and ideas effectively to multiple audiences. 

      5.Technology research tools 

• Students use technology to locate, evaluate, and collect information from a variety of sources.
• Students use technology tools to process data and report results. 
• Students evaluate and select new information resources and technological innovations based on the appropriateness for specific tasks. 

      6.Technology problem-solving and decision-making tools 

• Students use technology resources for solving problems and making informed decisions.
• Students employ technology in the development of strategies for solving problems in the real world.
