Today we did an experiment looking at the effects of sugar and salt on ice. What would happen if you sprinkled this onto ice cubes? Which one would melt the fastest?
There were three different dishes per group - our control (we added nothing to the ice cubes), sugar sprinkled on ice cubes and salt sprinkled on ice cubes.
Groups predicted what they thought was going to happen and then the experiment began. Over time we observed the reaction of sugar and ice on the ice cubes. We used timers to track the reaction that occurred over time.
Why not try this at home with your family? Do you think their predictions will be similar to yours?
Ask them to explain WHY they think this will happen.... but remember don't give anything away till after the experiment!!!
Want to know why this happened?
Explanation for the experiment
But wait there is more....
Hmmm - why do they talk about 32 degrees? Doesn't water freeze at a lower temperature than that?
If you want the full on scientific explanation then check out this video....
