APPENDICES A. Science SLP Curriculum Grade 4 Topic A: Waste and Our World General Learner Expectations Students will: 45 Recognize that human activity can lead to the production of wastes, and identify alternatives for the responsible use and disposal of materials. Specific Learner Expectation: Key Vocabulary: Language Skills: Other Skills: 1. Identify plant and animals wastes, and describe waste identifying how they are recycled in nature. For example, recycle describing plant leaves serve as a source of food for soil break down/ sequencing insects, worms and other creatures. The wastes of decompose these animals may then be further broken down soil by molds, fungi and bacteria. insect creature mold fungi bacteria 2. Identify and classify wastes that result from waste identifying human activity. activity classifying 3. Describe alternative methods of disposal, and disposal comparing/ evaluation identify possible advantages and disadvantages of advantages/ contrasting each. disadvantages identifying describing 4. Distinguish between wastes that are readily waste classifying biodegradable and those that are not. biodegradable comparing/contrasting 5. Compare different kinds of packaging, and infer packaging comparing/contrasting evaluation the relative advantages and disadvantages of that consumer inferences packaging. In evaluating different forms of environment pragmatics packaging, students should demonstrate the (perspective ability to consider a consumer perspective as well taking) as an environmental perspective 6. Identify methods of waste disposal currently methods identifying personal experience used within the local community. waste disposal local community 7. Identify kinds of wastes that may be toxic to toxic classifying people and to the environment. wastes environment 8. Identify alternative materials and processes materials identifying that may decrease the amount of waste processes produced. decrease 9. Identify ways in which materials can be reused reuse identifying brainstorming or recycled, including examples of things that the recycle describing personal experience student has done. 10. Develop a flow chart for a consumer product flow chart causeeffect hierarchy of that indicates the source materials, final product, consumer describing organization its use and method of disposal. product sequencing using resources source materials disposal 11. Identify actions that individuals and groups waste causeeffect brainstorming can take to minimize the production of wastes, to recycle identifying personal experience recycle or reuse wastes and to ensure the safe reuse handling and disposal of wastes. reduce/ minimize handling disposal 12. Develop and implement a plan to reduce waste brainstorming waste, and monitor what happens over a period plan (understanding procedure of time. what a good plan entails) monitor Topic B: Wheels and Levers General Learner Expectations Students will: 46 Demonstrate a practical understand of wheels, gears and levers by constructing devices in which energy is transferred to produce motion. Specific Learner Expectation: Key Vocabulary: Language Skills: Other Skills: 1. Explain how rollers can be used to move an rollers causeeffect procedure object, and demonstrate the use of rollers in a explaining practical situation. 2. Compare the wheel and the roller, and identify wheel comparing/ personal experience examples where each are used. roller contrasting identifying 3. Construct devices that use wheels and axles, and wheels describing procedure demonstrate and describe their use in: axles problemsolving • model vehicles model vehicle • pulley systems pulley system • gear systems. gear system 4. Construct and explain the operation of a drive drive system explaining procedure system that uses one or more of the following: belt problemsolving • wheeltowheel contact elastic • a belt or elastic chain • a chain cog • cogs or gears gear 5. Construct and explain the operation of a drive drive system explaining procedure system that transfers motion from one shaft to a shaft problemsolving second shaft, where the second shaft is: parallel • parallel to the first angle • at a 90° angle to the first. speed Students who have achieved this expectation will direction be aware of changes in speed and direction that result from different ways of linking components. 6. Demonstrate ways to use a lever that: lever causeeffect procedure • applies a small force to create a large force force • applies a small movement to create a large movement 7. Predict how changes in the size of a lever or the lever causeeffect position of the fulcrum will affect the forces and fulcrum inferences movements involved. Topic C: Building Devices and Vehicles that Move General Learner Expectations Students will: 47 Construct a mechanical device for a designated purpose, using materials and design suggestions provided. 48 Explore and evaluate variations to the design of a mechanical device, demonstrating that control is an important element in the design and construction of that device Specific Learner Expectation: Key Vocabulary: Language Skills: Other Skills: 1. Design and construct devices and vehicles that vehicle problemsolving procedure move or have moving parts linkages, wheels and linkage brainstorming axles wheel axle 2. Use simple forces to power or propel a device; power inferences procedure e.g., direct pushes, pulls, cranking mechanisms, propel moving air, moving water and downhill motion. crank mechanism motion 3. Design and construct devices and vehicles that vehicle problemsolving procedure employ energystoring or energyconsuming energystoring causeeffect brainstorming components that will cause motion; e.g., elastic energyconsuming bands, springs, gravity, wind, moving water. motion elastic spring gravity 4. Recognize the need for control in mechanical control problemsolving devices, and apply control mechanisms where mechanical inferences necessary. mechanism 5. Compare two designs, identifying the relative design comparing/ evaluation strengths and weaknesses of each. strength/ weakness contrasting 6. Identify steps to be used in constructing a device vehicle pragmatics procedure or vehicle, and work cooperatively with other problemsolving students to construct the device or vehicle. sequencing 7. Design and construct several different models of model pragmatics evaluation a device and evaluate each model, working problemsolving brainstorming cooperatively with other students. procedure Topic D: Light and Shadows General Learner Expectations Students will: 49 Identify sources of light, describe the interaction of light with different materials and infer the pathway of a light beam.
