Pulleys and Gears Pulleys and Gears Create a simple machine with a pulley, a gear or both. The machine must be able to complete a task that uses the pulley, gear or both properly. Rubric Code: LXAB657 By coolmom71 Ready to use Public Rubric Subject: Science Type: Project Grade Levels: K-5

Simple machine Project
	Level 1 (N/A)	Level 2 (N/A)	Level 3 (N/A)	Level 4 (N/A)
Understanding of basic concepts 3.1 describe the purposes of pulley systems and gear systems	Level 1 Student shows little understanding of the basic concepts.	Level 2 Student shows a partial understanding of the basic concepts.	Level 3 Student shows a good understanding of the basic concepts.	Level 4 Student shows an excellent understanding of the basic concepts.
Plan - Problem solving 2.3 use technological problem-solving skills (see page 16) to design, build, and test a pulley or gear system that performs a specific task	Level 1 The Plans are not precise, accurate or descriptive	Level 2 The plans are somewhat precise, accurate and/or descriptive.	Level 3 The plans are generally precise, accurate and/or descriptive.	Level 4 The plans are well thought out, are precise, accurate and well-described.
Communication 2.4 use appropriate science and technology vocab- ulary, including pulley, gear, force, and speed, in oral and written communication	Level 1 Student gives explanations that are incomplete, inaccurate and lacking in detail.	Level 2 Student gives explanations that are somewhat inaccurate and lacking in detail.	Level 3 Student gives explanations that are complete and generally accurate including most relevant details.	Level 4 Student gives explanations that are complete and accurate including relevant details.
Analysing and Interpreting 3.6 identify pulley systems (e.g., clotheslines, flagpoles, cranes, elevators, farm machinery) and gear systems (e.g., bicycles, hand drills, can openers) that are used in daily life, and explain the purpose and basic operation of each	Level 1 Student's analysis is missing, incoherent, illogical and/or not related to the design of their devices.	Level 2 Student does not clearly analyse their devices and/or the information given is only partially related to the design.	Level 3 Student gives a clear analysis of their devices and most information given is relevant.	Level 4 Student gives an excellent analysis of their devices and all the information is relevant.
