| A new twist on the “black box”............ Our black blocks look alike, but do they feel alike? More importantly, do they act alike?
Here’s an interesting and irrefutable way to prove the difference in heat conductivity in different metals. Place an ice cube on each of two similar black blocks at room temperature, sit back and watch. Do they melt at the same rate? Why or why not? The “cooler” block is of aluminum, which is an excellent conductor of heat. The “warmer” block is of plastic foam, which is a very poor conductor of heat. Contains: two black blocks with rim to prevent spillage, instructions with theory. This demo is great for all the doubting Thomases in your elementary through high school classes. Fast, easy and fascinating. |
