We’ve got quite a few candy canes leftover from Christmas so devised a little experiment to see how strong they are. Like many of our activities this is great for starting to think about experimental design and setting up a fair test. We discussed which variables to keep constant and how to make it a fair test.
How strong is a candy cane – test
Materials to strengthen your candy canes, such as plaster, bandage, sellotape
Decorations of different weights.
How to test a candy cane
Choose several Christmas decorations of different weights, hang each onto the end of a candy cane for a fixed amount of time. We tried each for 30 seconds.
Try to find a decoration heavy enough to break the candy cane. Once you’ve done this, attempt to strengthen a new candy cane with different materials. Can you find anything strong enough to hold the heaviest decoration?
