Draw pictures of children at textiles, forced to work in factories or laboring on farms. Depict worn out clothing, starving children, maybe types of implements used to punish those who fell behind in their work. Or if drawing is not your style, use a stick to represent a switch or whip, bring ragged cloths or ripped jeans to resemble how bad their condition was, bring an empty bowl to signify that they were starving. Just an opinion, but this is what I did for mine and got full credit plus a little extra bonus for multiple displays. Hope this helps you.
