Year 7 Science Separating Mixtures Assignment Your task is to find out about ONE of the following topics. Each one relates to an example of separating mixtures and will help you discover how the processes we have learnt about are relevant in the real world.

Correct scientific terms have been used to describe the separation process. Most necessary terms have been explained. Correct scientific terms have not been used to describe the separation process OR the terms have not been explained. Moderate explanation of who is involved in the separation processes and where they occur OR no map included. Has listed 3 interesting facts related to the topic that have not been previously covered in any other question. Clearly explained language in own words, with correct spelling & use of grammar Limited explanation of who is involved in the separation processes and where they occur. No map included.
