Solubility Kitchen
A liquid can dissolve only a limited amount of solute at a given temperature. Heating usually raises that limit, while cooling can make some dissolved solute become solid again.

What your child will figure out
- Identify visible undissolved solid as evidence that a solution is saturated.
- Predict and test whether adding more solute to a saturated solution changes the dissolved amount.
- Predict how heating and cooling change the amount of sugar that can stay dissolved.
- Account for all solute as dissolved plus solid, even when it cannot be seen in the liquid.
The levels
- Find the limit
Add, stir, and observe until visible solid remains and identify the solution as saturated.
- Predict the next scoop
Predict whether another scoop will dissolve in an already saturated solution, then test it.
- Turn up the heat
Predict and observe how heating changes sugar's dissolving capacity.
- Cool-down transfer
Transfer the saturation rule to cooling and account for re-formed crystals without losing mass.
Ready when they are.
