Wilson's School homework Year 8

Wilson's School Design & Technology 1

YEAR 8

Whenever I have an idea I write it down, even if it’s not a very good idea. Sometimes the bad ideas will lead to better ones.

- James Dyson

How does this document work?

This document has all the homework to be completed by

all Yr8 students.

All homework tasks are to be completed for the next

lesson after the homework is set.

The images in the document are taken from online

resources each image should have a link to its origin.

All resources can be found on the Wilson's Design and

Technology webpage

http://www.wilsonsschool.sutton.sch.uk

What are you expected to complete?

Each section gives instruction on what is to be completed.

Students can choose the way in which they answer the

homework task (drawing, written, storyboard etc)

Students can complete the homework in any media they

wish (by hand, on word, PowerPoint, online) but a physical

copy must be submitted during the lesson. On a USB is not

acceptable.

How do the homework tasks work?

There are three sections: Knowledge, Application and

evaluation.

In the knowledge section you need to answer at least three

of the questions

In the application section you need to use one or more of

the presentation methods

In the evaluation section you need to answer two or more

of the questions.

This must be completed for all home works!
