They construct a lever and investigate mechanical advantage by experimenting with the position of the fulcrum, load, and effort. They discover the mechanical advantages and disadvantages of each system. Energy and Communications is designed to be completed over a 4-to 6-week period. Seven science themes are incorporated into the program; the themes are energy, evolution, patterns of change, scale and structure, systems and interactions, unity and diversity, and stability. Examples include consumable and nonconsumable activity materials; audio- and video-tapes; interactive videodiscs; color transparencies; assessment materials; a teacher anthology of short stories, poems, fingerplays, and songs; trade books; teacher resource masters; activity cards; activity logs; a staff development package; concept summaries and glossaries for students acquiring English; and software with problem-solving simulations for students.
Assessment Guide The Assessment Guide contains 2 sets of tests—multiple choice questions and essay questions—for each of the 12 chapters. A textbook explains things in a way that I cannot. Materials: Available locally, or from commercial suppliers. Other features of this book include problem-solving challenges, science career descriptions, and science connections to real-world events or issues. Price and Acquisition Information Ordering information appears at the end of each entry. The subject of each unit—for example, changes in matter—is presented from the perspective of one or more of these themes.
In addition to directions for activities, the teacher's guide provides a module overview, a schedule of activities, objectives for each activity, background information, materials management and preparation tips, sample answers to discussion questions, teaching suggestions, and reinforcement activities. Teacher's Guide Recommended grade level: 7-8. Other skills-oriented activities are also suggested for discovering, doing, calculating, thinking, and writing about science. They measure altitude, wind speed, rate of descent, and flight distance. Materials: Available locally, from commercial suppliers, or in kit. Inventor's Lab provides a list of resources, including books, computer software, and audiovisual materials. Teacher's Planning Guide This teacher's planning guide, a spiral-bound, wraparound edition, provides information and strategies for teaching the 5 lessons in the student edition.
He joins us for the labs though. New York: Oxford University Press. Using readily available and inexpensive materials, students experiment and find out how lenses are used in magnifiers, simple cameras, telescopes, and projectors. Problem-Solving Activities for Middle-Level Science series. In lab investigations, students use a Slinky to observe the characteristics of a wave; they experiment with tuning forks to explore sympathetic vibration, resonance, interference, beats, and the Doppler effect; they record the temperatures produced by different colors of light; and they observe the images formed by a convex lens.
Earning both a master's and doctoral degree requires even further specialization through a thesis and dissertation project, respectively, and can take up to seven years of study beyond the bachelor's degree. Physical science uses the theory as the commonly accepted scientific theory of the origin of the universe. Also included are reproducible activity sheets for student work and a performance-based assessment. In a unit on electromagnetism and sound, students make an electromagnet and use it to build a working speaker. Chemistry is chiefly concerned with and and their interactions and transformations, for example, the properties of the formed between atoms to create. Each curriculum annotation has a two-part entry number: the chapter number is given before the period; the number after the period locates the entry within that chapter. They also build a photophone and use it to send and receive messages.
Teacher's Edition In the teacher's wraparound edition, each chapter begins with a 2-page planning guide and a 2-page preview that summarizes each section within the chapter. Students explore the melting points and conductivity of ionic and covalent compounds, and they see how the concentration of a substance affects reaction rate. The difficulty with any representation that divides the system is the danger of continuing a deconstructed perception of the holistic Earth system - in reality no part of the Earth system can be considered in isolation from any other part. Other activities involve making saturated solutions of salt and citric acid and then comparing the solubility of these 2 substances in water; determining the relative concentration of salt solutions; and observing chemical reactions that result in the formation of a gas and a precipitate and then applying the techniques of filtering and evaporation to separate some of the reaction products. Students also study practical applications of heat, such as the use of the principles of heat energy in direct and indirect heating systems, insulation, cooling systems, and heat engines.
In addition to directions for activities, the teacher's guide provides a module overview, a schedule of activities, objectives for each activity, background information, materials management and preparation tips, sample answers to discussion questions, teaching suggestions, and reinforcement activities. Background information for the teacher, summary outlines, and reproducible student worksheets are included. In the third and fourth activities, students investigate the concepts of concentration and neutralization and apply what they have learned by testing a variety of new liquids and household products. Seven science themes are incorporated into the program; the themes are energy, evolution, patterns of change, scale and structure, systems and interactions, unity and diversity, and stability. Simple Machines introduces students to simple machines and the concepts of force, work, friction, energy transfer, and mechanical advantage. The student edition closes with 3 readings: about physicist Shirley Ann Jackson, acid rain, and the possibility of factories in space. The unit's 12 classroom tabletop activities provide open-ended explorations in an informal, student-centered setting.
Materials: Available locally, or from commercial suppliers. They conduct a series of physical and chemical tests to discover which nutrients—starches, glucose, fats, and proteins—are in common foods. Earth system science embraces chemistry, physics, biology, mathematics and applied sciences in transcending disciplinary boundaries to treat the Earth as an integrated system and seeks a deeper understanding of the physical, chemical, biological and human interactions that determine the past, current and future states of the Earth. Materials: Available locally, from commercial suppliers, or in kit. The series is designed to teach key science and mathematics concepts through activity-based learning. I purchased this last year and have been working hard at making it work for us.
Anthea Maton, Jean Hopkins, Susan Johnson, and others. Materials: Available locally, from commercial suppliers, or in kit. Students also read about the development of the periodic table and gain an understanding of metals, nonmetals, and metalloids. About 35 of these are appropriate for middle school. Other available materials include videotapes, interactive videodiscs, transparencies, assessment materials, English and Spanish guides for language learners, a study guide, a teacher's desk reference, and a booklet of product-testing activities. Each requires about 3 to 4 weeks to complete and includes a teacher's guide and materials for a class of 32 students.
