Reversible and Irreversible Changes

Today in science we became secret agents and had to complete missions on irreversible and reversible changes 

We began by looking at ice cubes. We placed them in our hands and melted them to a liquid (water). We know this is a reversible change as we can freeze them back to ice cubes.

We also looked at burning a match and how is an irreversible change as it can not be changed back to wood once it is burnt.

We then had to investigate whether cooking an egg is reversible or irreversible.

What do you think it is and why? Post your comments below!
