This lesson forms the second lesson in the AQA 2016 specification 4.7 organic chemistry scheme of work and comes after lesson 1 crude oil. The lesson is designed to develop independent practical skills - something that is often developed at Key Stage 3 when there is more curriculum time but is missed out at GCSE in order to cover all of the subject content needed for the exams. The lesson begins with considering the properties that a good fuel should have. It is worth pointing out to students that these are the main properties of hydrocarbons. Alkanes and alkenes are covered later in this scheme of work so reference is not made to them in this lesson. Students then read two sources and choose one of them to write a summary on their method sheet. They then carry out a risk assessment of the method that they have chosen. The practical that they do is using a pipette with a small hole in the side - these need to be prepared in advance by the technicians. Students put the pipette in the oil and then cover the hole as they lift up the pipette. They then open the hole (move the finger of the way) and time how long it takes for the oil to move from 3m to 1ml. The lesson finishes with an exam plenary question (markscheme is provided). It is suggested that water baths are used to heat the jars or beakers of vegetable oil. Please rate this resource and leave feedback.
