Product Description
Why does the "cold' block melt ice quicker than the "warm" block?
You have two blocks very similar in appearance. But the one feels colder to the touch than the other. This is also the one that melts the ice cube within 3 minutes while the "warm" block does not melt its cube at all. And then when you measure the surface temperatures, you find that they both have the same temperature!!
Now: Why does the one feel colder? Why does the one melt the ice quicker? Is melting an endothermic process? Why do we prefer to step onto carpeted floors rather than tiled floors in the bathroom?
Great for provoking science thinking and enquiry with two unexpected (discrepant) events.
Included: Two ice melting blocks, two o-rings to contain the melting water on the blocks, full instructions Required: Ice cubes and IR thermometer (optional)
Teach: Heat conduction, heat flow, endothermic processes, melting, scientific enquiry
