Looking for material and/or presentation for 9th year students

Hello All.

We are working with 9th grade students (smart ones!!) to get an idea from a thought to a real product (hopefully ).

My role is to tell them about the mechanical aspect of the creation.

My time is limited to a hour and half presentation and around a week of hands on experience.

I would like to give them a quick lecture/demonstration of the CAD in general and SolidWorks capabilities and usage.

I am looking for material to help me demonstrate it and maybe someone had performed this type of presentation and will be able to share it with me.

I know there is a complete section of education with full curriculum, but it is based on around 3 months time of hands on class. I need something short and to the point that they will be able to understand the concept and also follow my sample and create some draft of there own.
