Worksheet to go alongside calorimetry experiment comparing energy per gram of fuel for different length hydrocarbons. Work is scaffolded for students to discuss control variables and hard to control variables, which acts as good practice for controlled assessments. Following completion of a calorimetry practical students calculate energy transferred and energy per gram using the key equations plus rearrangement of equations. Students are extended through link to exothermic energy profiles. Designed for students entered into higher exam for OCR Gateway Additional Science B / OCR Gateway Chemistry B, and is graded according to specification.

Worksheet that was used as short homework for topic C6 of OCR Gateway Chemistry B so that students were prepared for a subsequent lesson on how fuel cells work (1sided, see preview)

Worksheet for C6 Detergents - OCR Gateway. Scaffolded and graded using specification - higher tier.
