I can carry out an investigation with help
I can explain that when a solid dissolves it can’t be seen but it remains in the solution eg we couldn’t see the salt any more but it was still there, the salt went into the solution
I can explain that when water evaporates from a solution, solids are left behind because they were dissolved in the solution but don’t evaporate
I can identify a range of factors which might affect how fast solids dissolve
I can present results, perhaps with some help, in a bar chart or line graph, and explain what the results show.
