Growing Crystals

In science we have been investigating reversible and irreversible changes. We found out about the processes of dissolving and evaporation, finding out that by evaporating the liquid from a solution then the solid that is dissolved in it can be retrieved.

We mixed sodium bicarbonate and cream of tartar (two common cooking ingredients) together to make a solution, then left the solution to evaporate. After a long wait we managed to make some crystals. Below is a photograph of some of our crystals.
