Developing design ideas further, using understanding of mechanisms

In this lesson, we will continue to develop our design ideas. We will learn how to label and annotate our ideas, explaining how it is suitable for our intended users, and how the mechanisms will work. This lesson includes equipment beyond pen, paper or pencil. Please make sure your child is adequately supervised.
