Hi, I'm doing a science fair and they're asking us to put pictures of us doing experiments or to bring in a model. In my project I experimented on people so was I supposed to take pictures of people performing the tasks? I already did the project and experiments and did them at a mall, if I had to take pictures what should I do? And if I need a model what should it be?

Question

If it helps my project is on multitasking. I was trying to see if people work better while multitasking or without and I also compared if it was easy or hard for them.

-Thank you in advance
