What is 9th grade Design?

I am new to IB, and will be teaching at an IB school this year. I come from a traditional public school. One of the classes I will be teaching is 9th grade Design. I was sent the link of the description but it’s very vague. Can anyone explain what it is? In layman’s terms what would we be doing and what would I be teaching? I am going to be given resources from previous teachers, so I’m not starting from scratch but any advice, suggestions, or recommendations?
