As part of our homework over Easter, Mr R has asked us to collect 10 reversible and 10 irreversible changes. Once these have been collected, post them onto the blog by adding a comment below. Mr R will publish these on the last weekend of the holidays. The 10 people who give an obscure answer (eg examples which nobody else have given – eg ‘Pointless’ answers) will each receive a team point. Good luck!
I found melting chocolate,burning wax,using a stock cube,caramel,toffe,butter,juice,ice lollies and ice,a blacksmith forging iron are all reversible changes.I also found baking a cake,frying an egg,burning wood,burning paper,cutting trees down,making milk into cheese and yougut,cutting veg or fruit,painting a wall,breaking down a house and smashing a plate all irreversible.
