Separating a Mixture using Evaporation

Aim: to separate the solute from the solvent / making crystals

Hypothesis: I actually have no idea on what's actually going to happen

Equipment:
Copper sulfate solution, 250 ml Beaker, Heat proof mat, Evaporating basin, Element.

Method:
1. Set up Element
2. Add 100 ml of hot water into the beaker and place on the element
3. Add copper sulfate to the evaporating basin until it is quarter full
4. Carefully, place the Evaporating basin on top of the beaker
5. Turn on the Element
6. Heat the solute until most of the solvent has been evaporated and crystals of the solute is forming
7. Turn the element off, careful not to touch as will be hot for a long time

Observation:
It is starting to steam and boiling and the copper sulfate on top of the beaker is starting to lessen up.
After a few minutes, the copper sulfate started to harden up and is also starting to look like a crystal but in one big whole.

This is what the Crystal ended up looking:
