What happens when a candle is alight is the subject. Explained both changes using the Big Idea of Energy?
A physical change-the wax starts to melt
A chemical change - light and heat energy is produced
the difference between chemical and physical changes are that you can measure and see physical changes wheres you cant or a chemical change.
for the reacts its
hydrogen+oxygen equals water
carbon+oxygen equals carbon dioxide
the wax contains both hydrogen carbon ( called hydrocarbons)and h2o
that's all I can do. Hope this helps.
So, overall, maybe you can do a poster with some information of what happens with a lit candle and maybe draw a candle on the poster.
