This dissolving candy canes activity is a great science activity for before Christmas when the festivities are in full swing or after Christmas to use up any leftover candy canes.
The idea is to place candy canes in different liquids to find where they melt the fastest. We used hot and cold water and vinegar, but different hot chocolate temperatures would also work well.
Dissolving candy canes is an excellent investigation for learning how to set up a fair test! This means you need to think about which variables you change and which you keep the same.
Controlled variables are things you keep the same. In this investigation, the controlled variables are:
- size of candy cane
- time the candy cane is in the liquid
- amount of liquid used
The independent variable is the thing you change. In this experiment, the independent variable is the liquid in which the candy canes are sat.
The dependent variable is the thing you measure. In this investigation, the time it takes for the candy cane to dissolve is measured.
Candy Cane Experiment – dissolving candy canes
You’ll need the following:
Three containers of the same size
Vinegar
Cold Water
Hot Water
Method
Set up your containers. Take care with the hot water.
Add a candy cane to each container the same way up.
Observe each candy cane at 5-minute intervals ( can you design a table to record your observations? )
Results
The photo below shows our final results after 20 minutes.
Vinegar is on the left, cold water is in the middle, and hot water is on the right.
You can see that the vinegar completely dissolved the submerged candy cane, the cold water just dissolved the outer layer and the hot water dissolved past the outer layer making the submerged section break off.
The thing we found most interesting was that the hot water turned red, and the vinegar and cold water turned grey.
Record the results on the handy dissolving candy canes instruction sheet below.
