SCSD 7 th GRADE SCIENCE CURRICULUM About this document Identified within each unit is the Declarative and Procedural Knowledge to be mastered by students as a result of classroom instruction. In support of these, instructional strategies and activities have been included. The Declarative Knowledge identifies a basic learning progression that students may follow in developing an understanding of the concepts that help them to answer the essential question of the unit. In this learning progression the writing team referenced the Project 2061 Atlas of Science Literacy. In comparing the NYSED Science Core Curriculum to this document gaps were identified that possibly could limit student’s ability to make connections between sub-learning’s. These additional learning’s are in italics under the Declarative Knowledge column. While they are not required by NYSED it is suggested that these be taught to students. At the bottom of each page are the links to the NYSED Intermediate Level Science Core Curriculum and the Project 2061 Atlas of Science Literacy. Once in these documents you can directly reference the specific major understandings.

NYS Performance Indicator S1.1 S1.2 S2.1 S2.2 S3.1 S3.2 Declarative Knowledge: To Know Procedural Knowledge: To Do The central purpose of scientific inquiry is to develop explanations of natural phenomena. Observations lead to questions, which may lead to more questions in the search for explanations. Models help to explain phenomena. o observation/observe o hypothesis/hypothesize o inference/infer o prediction/predict o explanation/explain Scientific inquiry involves the testing of proposed explanations by using conventional techniques, procedures, and ingenuity. Scientific investigations can be conducted to test proposed explanations (or hypotheses). Controlled investigations include a control group (constant) and an experimental group containing a dependent and an independent variable. Dependent variables (responding variables) Using appropriate references, formulate questions independently that will be useful in guiding the search for explanations of everyday observations. Formulate questions about natural phenomena and identify appropriate references to investigate a question. Refine and clarify questions so that they are subject to scientific investigation. Construct explanations independently for natural phenomena, especially by proposing preliminary visual models of phenomena. Independently formulate a hypothesis. Differentiate among observations, inferences, predictions, and explanations. Design charts, tables, graphs, and other representations of observations in conventional and creative ways to help them address their research question or hypothesis. *Demonstrate appropriate safety techniques. *Conduct an experiment designed by Atlas 2061: http://strandmaps.nsdl.org/ 4 New York State Core: http://www.emsc.nysed.gov/ciai/mst/pub/intersci.pdf Instructional Strategies Assessment /Laboratory Investigation /Activities Observing Questioning Hypothesizing Inferring Predicting Constructing Models Writing explanations Journal Response Activity: Use conventional techniques and those of their own design to make further observations and refine their explanations, guided by a need for more information (so any inquiry-based lab).

Matter is anything that takes up Project 2061 space and has mass. Matter is classified as Atlas of a substance or a mixture of substances. Science Most substances can exist as a solid, liquid, Literacy or gas depending on temperature. SFAA p. 47 In solids, the atoms or molecules are closely locked in position and can only vibrate. In liquids, they have higher energy, are more loosely connected, and can slide past one another; some molecules may get enough energy to escape into a gas. In gases, the atoms or molecules have still more energy and are free of one another except during occasional collisions. 4D/M3cde The motion of particles helps to explain the phases (states) of matter as well as changes from one phase to another.

NYS Performance Indicator PS 4.1 PS 4.3 PS 4.5 Italicized words are from the Project 2061 Atlas of Science Literacy Declarative Knowledge: To Know Most activities in everyday life involve one form of energy being transformed into another. For example, the chemical energy in gasoline is transformed into mechanical energy in an automobile engine. Energy, in the form of heat, is almost always one of the products of energy transformations. PS 4.1c Different forms of energy include heat, light, electrical, mechanical, sound, nuclear, and chemical. Energy is transformed in many ways. PS 4.1d Energy can be considered to be either kinetic energy, which is the energy of motion, or potential energy, which depends on relative position. PS 4.1e Energy cannot be created or destroyed, but only changed from one form into another. PS 4.5a Energy appears in different forms and can be transformed within a system. Motion (Kinetic) energy is associated with the speed of an object. Thermal energy is associated with the temperature of an object. Gravitational energy is associated with the height of an object above a reference point. Elastic Potential Procedural Knowledge: To Do Describe energy changes as related to chemical reactions.

Lab: Students build an electromagnet and investigate the effects of using different types of core materials, Katrina Allen, Kelly Colone, Naomi Ludwig, William Ottman May 2010 energy is associated with the stretching or compressing of an elastic object. Chemical energy is associated with the composition of a substance. Electrical energy is associated with an electric current in a circuit. Light energy is associated with the frequency of electromagnetic waves. 4E/M4 Whenever energy appears in one place, it must have disappeared from another. Whenever energy is lost from somewhere, it must have gone somewhere else. Sometimes when energy appears to be lost, it actually has been transferred to a system that is so large that the effect of the transferred energy is imperceptible. 4E/M1 Energy can change from one form to another, although in the process some energy is always converted to heat. Some systems transform energy with less loss of heat than others. PS 4.5b In chemical reactions, energy is transferred into or out of a system. Light, electricity, or mechanical motion may be involved in such transfers in addition to heat. PS 4.3a Energy can be transferred from one system to another (or from a system to its environment) in different ways: 1) thermally, when a warmer object is in contact with a cooler one; 2) mechanically, when two objects push or pull on each other over a distance; 3) electrically, when an electrical source such as a battery or generator is connected in a complete circuit to an electrical device; or 4) by electromagnetic waves. 4E/M2 Atlas 2061: http://strandmaps.nsdl.org/ 16 New York State Core: http://www.emsc.nysed.gov/ciai/mst/pub/intersci.pdf varying thicknesses of wire, and different circuit types.

NYS Performance Indicator PS 4.4 Italicized words are from the Project 2061 Atlas of Science Literacy Declarative Knowledge: To Know Vibrations in materials set up wave-like disturbances that spread away from the source. Sound waves are an example. Vibrational waves move at different speeds in different materials. Sound cannot travel in a vacuum. PS 4.4c Wave behavior can be described in terms of how fast the disturbance spreads and in terms of the distance between successive peaks of the disturbance (the wavelength). SFAA p. 54 Light passes through some materials, sometimes refracting in the process. Materials absorb and reflect light, and may transmit light. To see an object, light from that object, emitted by or reflected from it, must enter the eye. PS 4.4b Something can be "seen" when light waves emitted or reflected by it enter the eye. 4F/M2 Light travels and tends to maintain its direction of motion until it interacts with an object or material.

Magnetic forces are very closely related to electric forces and are thought of as different aspects of a single electromagnetic force. Moving electrically charged objects produces magnetic forces and moving magnets produces electric forces. 4G/H5ab Without touching them, material that has been electrically charged attracts uncharged material, and may either attract or repel other charged material. PS 4.4f Without direct contact, a magnet attracts certain materials and either attracts or repels other magnets. The attractive force of a magnet is greatest at its poles. PS 4.4g Without touching them, a magnet pulls on all things made of iron and either pushes or pulls on other magnets. 4G/E2 A bar magnet may be cut into multiple pieces and retain its southern and northern poles. Magnetic force can pass through many materials with no apparent decrease in strength. Electric currents and magnets can exert a force on each other. PS 5.2b An electric current in a wire and a magnet near a coil of wire induces electric current when there is movement.

NYS Performance Indicator PS 5.1 PS 5.2 Italicized words are from the Project 2061 Atlas of Science Literacy Declarative Knowledge: To Know Procedural Knowledge: To Do The motion of an object is always judged with respect to some other object or point. The idea of absolute motion or rest is misleading. PS 5.1a The motion of an object can be described by its position, direction of motion, and speed. PS 5.1b An object’s motion is the result of the combined effect of all forces acting on the object. A moving object that is not subjected to a force will continue to move at a constant speed in a straight line. An object at rest will remain at rest. (Newton’s First Law) PS 5.1c Force is directly related to an object’s mass and acceleration. The greater the force, the greater the change in motion. (Newton’s Second Law) PS 5.1d For every action there is an equal and opposite reaction. The greater the force is, the greater the change in motion will be. (Newton’s Third Law) PS 5.1e Unbalanced force acting on an object changes its speed or direction of motion, or both. 4F/M3a If a force acts toward a single center, the object's path may curve into an orbit around the center. 4F/M3b The change in motion (direction or speed) of an object is proportional to the applied force and inversely proportional to the mass. 4F/H1 Every object exerts gravitational force on every other Determine the speed and acceleration of a moving object. PSS-16 Force = mass x acceleration Acceleration = force / mass Safely and accurately use the following measurement tools: metric ruler, and spring scale. Identify the relationship between motion and a reference point. Identify the two factors upon which speed depends. Determine the speed and acceleration of a moving object. Interpret a graph showing acceleration. GS-9 Calculate average speed. Calculate average acceleration. Construct a device that detects acceleration. Compare balanced and unbalanced forces.

PS 5.2c Friction is a force that opposes motion. PS 5.2d A machine can be made more efficient by reducing friction. Some common ways of reducing friction include lubricating or waxing surfaces. PS 5.2e Machines can change the direction or amount of force, or the distance or speed of force required to do work. PS 5.2f Simple machines include a lever, a pulley, a wheel and axle, and an inclined plane. PS 5.2g A complex machine uses a combination of interacting simple machines, e.g., a bicycle.
