<human>: Can you give me the gist of the text in a nutshell?

My younger brother had signed up for an engineering camp this summer. He was really excited for this opportunity. He's a junior in high school right now and wants to get into engineering when he graduates. However, our school isn't very techy, and he hasn't had a chance to observe or learn about many different types of engineering.
We found out today that this summer camp was cancelled. He's devastated. He was also planning on using the experience here as part of his senior project.

So what I'm here for - do you guys have any ideas of varied engineering projects I could do with him over the course of a few weeks? Preferably, I would like to give him an idea of multiple types of engineering - mechanical, chemical, material science, electrical, etc. Also, we won't have much money to work with. But I would absolutely welcome any and all ideas for little engineering projects or other things we could do this summer to get him more interested in engineering.

It will be difficult as I'm at graduate school and he's at home. He is planning on visiting for a week or two, though. I can possibly try and get some resources from my university to use, as well, but I'm not sure how much I could do there. I did go to this school for engineering as my undergraduate degree in biological engineering, so you have at least an idea of what I can do and why I think I could pull of this workshop for him. But I'm not really sure what little projects we could do, as my degree focused on biomedical engineering and most of that won't be feasible for him.
<bot>: Engineering camp for my younger brother was cancelled, I want to put on an engineering workshop for him, do you have any ideas of projects I could do with him? Thanks!!
