Physics ideas click fastest with real practice. This set gives your Grade 6-8 class ninety questions on input and output energy.
The set includes questions like "How can improving energy efficiency impact waste energy?", "If a system outputs 50 J of useful energy and has an input of 100 J, what is the efficiency?", and "What happens to waste energy in a closed system?"
Because the three worksheets share the same content in three different formats, you can spread them across the week: one for diagnosis, one for practice, and one for assessment, without repeating a single question.
This set is part of a NGSS aligned physics unit. The unit also covers Work and Energy, Efficiency Calculations, Energy in Simple Machines, Comparing Device Efficiency, Insulation and Energy Loss, and Case Study Energy in Homes, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 6-8 physics classes, and for review at any point in the school year. This set is aligned to NGSS standard MS-PS3-4.
