Endeavour loved looking at chemical reactions9 November 2020 (by Beth Taylor (Beth)) |
In science today we looked at reversible (physical) changes and irreversible (chemical) changes.
Not only did we watch foaming reactions and instant (well, in an hour) rusting, we also acted out being the molecules in water - starting as ice, working our way up to water vapour and back again. Ask us to explain what happens to the molecules as the heat rises or cools.
