Chemical change: you should probably put a log burning
Homeostasis: you should draw the human body -the lungs and this as such showing if that's your level of drawing-
Stable: you should maybe draw a human being standing on one leg and completely balanced or in control of their body
Id help you draw these things cos i guess im pretty good *looks at the screen* but emm that's not gonna happen -_-||
Anyways Hopefully this helps ^-^
