 * Brooklyn Middle School Seventh Grade Science Standards **

** Grade 7 ** **Core Themes, Content Standards and Expected Performances** || ¨ Work is the process of making objects move through the application of force. ¨ Energy can be stored in many forms and can be transformed into the energy of motion. || ** C 1. ** Explain the relationship among force, distance and work, and use the relationship (W=F x D) to calculate work done in lifting heavy objects. ¨ All organisms are composed of one or more cells; each cell carries on life-sustaining functions. ¨ Multicellular organisms need specialized structures and systems to perform basic life functions. || ** C 4. ** Describe the basic structures of an animal cell, including nucleus, cytoplasm, mitochondria and cell membrane, and how they function to support life. ¨ Volcanic activity and the folding and faulting of rock layers during the shifting of the Earth’s crust affect the formation of mountains, ridges and valleys. ¨ Glaciation, weathering and erosion change the Earth’s surface by moving earth materials from place to place. || ** C 7. ** Describe how folded and faulted rock layers provide evidence of the gradual up and down motion of the Earth’s crust. ¨ Various microbes compete with humans for the same sources of food. || ** C 10. ** Describe how freezing, dehydration, pickling and irradiation prevent food spoilage caused by microbes. ||
 * This framework articulates the main conceptual themes and content standards that all students are expected to learn in their seventh grade middle school science class. **
 * **Content Standards** ||  **Expected Performances**  ||
 * // Energy Transfer and Transformations – What is the role of energy in our world? //
 * 7.1 ** - **Energy provides the ability to do work and can exist in many forms.**
 * C 2. ** Explain how simple machines, such as inclined planes, pulleys and levers, are used to create mechanical advantage.
 * C 3. ** Describe how different types of stored (potential) energy can be used to make objects move. ||
 * // Structure and Function – How are organisms structured to ensure efficiency and survival? //
 * 7.2 - Many organisms, including humans, have specialized organ systems that interact with each other to maintain dynamic internal balance. **
 * C 5. ** Describe the structures of the human digestive, respiratory and circulatory systems, and explain how they function to bring oxygen and nutrients to the cells and expel waste materials.
 * C 6. ** Explain how the human musculo-skeletal system supports the body and allows movement. ||
 * // Energy in the Earth’s Systems – How do external and internal sources of energy affect the Earth’s systems? //
 * 7.3 - Landforms are the result of the interaction of constructive and destructive forces over time. **
 * C 8. ** Explain how glaciation, weathering and erosion create and shape valleys and floodplains.
 * C 9. ** Explain how the boundaries of tectonic plates can be inferred from the location of earthquakes and volcanoes. ||
 * // Science and Technology in Society – How do science and technology affect the quality of our lives? //
 * 7.4 - Technology allows us to improve food production and preservation, thus improving our ability to meet the nutritional needs of growing populations. **
