Reversible and irreversible changes

This afternoon, Hawk class have had great fun investigating irreversible changes. We mixed milk and vinegar together to make a new solid and we mixed bicarbonate of soda and vinegar together to make a gas.

Can the children explain the chemical reaction? Perhaps they could comment below explaining what happened.

    In science we mixed milk with vinegar and stirred it until we had lumps and guess what we made we made plastic if you stir milk with vinegar it makes plastic so that is what we did Monday.
