Human Body - Organs research tasks - differentiated

I created these tasks for my mixed ability Year 3 class, but they would be suitable to use with younger or older pupils too. As part of our human body topic, I wanted them to do some research about organs, and set this for homework, although it could of course be done in class too if you have non-fiction books/iPads/laptops available to use for research.
There are three differentiated tasks (all saved in one file):
'Less able' - Matching task where pupils have to research the appearance of the main organs so they can match images of them to the correct names.
'Middle group' - Research the main organs, and write a brief description of what each one does.
'More able' - Choose one of the main organs, research it and complete a fact sheet about it, describing its size, position, function and drawing a labelled picture of it.
