Here is an activity that I am doing with year 7 and 8 as a general skills lesson they have. You could easily use this for KS4, which presents a number of skills which employers will look for.
A lesson I created on Human Genetic Engineering. Let me know what you think.<br />
(I did use a variety of sweets instead of play-doh for starter - along with cocktail sticks and marshmallows)
I created this lesson as part of a unit of work looking at different faiths and considering what makes a religion, a religion. <br />
Let me know what you think.
