Spring 1

Organic 1

Complete any 2 of the following home study tasks:

1. Crude oil is a finite resource. Research the theory called ‘peak oil’. Use this information to write a letter to the prime minister explaining the problems that we may face in the future and suggest some solutions. Your letter should include lots of scientific facts but should also be enjoyable to read!

1. Fractional distillation is the process of separating the mixture of hydrocarbons in crude oil. Imagine that you are a hydrocarbon and draw a cartoon to show what would happen during the process of fractional distillation. (HINT: remember to include the forces between the molecules)

1. Create a song or rap that describes the different properties that different hydrocarbons have. Make sure that you include some information about how this influences the use of the fuel and how the properties are related to the size of the hydrocarbon chain. Could you perform this to the class!

1. Cracking is a process in which large hydrocarbon chains can be broken down into smaller molecules using heat and a catalyst. Research the product that is created when the cracking process is used to break kerosene down. What useful product is made? What could be done with the left overs? Make a creative way to display the answers to these questions.

Spring 2
