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. You will use your research to do one of the following:
-
Create a small (A3) poster
Make a movie
Make a video (e.g. using a program like ‘Powtoon’)
Write a ‘day in the life of….’ story from the perspective of a person involved in the separating
process
Another presentation format as approved by your teacher
Each topic lists the key questions that you will need to answer, page references from your text book
and where you could find more information……
YOUR FIRST RESOURCE SHOULD BE YOUR TEXT BOOK…..followed by the suggested websites.
