make your own from a black ceramic tile and black foam board and save tons!

Great for elem physics kids

Comments about Arbor Scientific Ice Melting Blocks:
As an introduction to heat transfer these blocks are great. Students tend to think that the warm feeling block will melt the ice faster....not true!

Comments about Arbor Scientific Ice Melting Blocks:
The ice cube on the metal block starts to melt immediately. (Watching ice melt is neater than you might think.) We combined this demo with other ice activities:
1) two small glass bowls with an ice cube each--sprinkle salt one one of the cubes
2) tall container with water and oil--guess where the ice cube will float and what will happen as it melts

Comments about Arbor Scientific Ice Melting Blocks:
We purchased one set as a "time filler" for a thermodynamics activity for our annual Science Day (elementary school). The original activity idea did not materialize. So we developed the 20 minute activity around the melting blocks demonstration (plus a discussion about how we use insulation daily). Although this was not a hands on activity for the children (we only used one set), it was one of the best sessions we had!

Comments about Arbor Scientific Ice Melting Blocks:
I haven't used this yet because we have passed this unit for the year, but I am planning on using it for the final exam review to remind them that heat flows into cold areas, not the other way around.

Comments about Arbor Scientific Ice Melting Blocks:
A great intro to thermo, really gets the kids thinking!
Comments about Arbor Scientific Ice Melting Blocks:
I used as a "hands-on" prediction of which one would melt a cube of ice faster... Both squares look alike and except for the cold feeling of the aluminum... student usually predict the wrong one... that it will melt faster... Great discussions when they start to put three-six ice cubes on the aluminum and watch them melt while only one is barely melting on the polymer insulation.
Comments about Arbor Scientific Ice Melting Blocks:
Students touch each of the two blocks and then make a prediction as to which one will melt a piece of ICE first... and why... They almost always predicted the aluminum because it felt cold... But I do a surface test with a infra-red thermometer, I get the same temperature... that brings up lots of discussion... We then put Ice on both pieces and within a few seconds the one with aluminum is melting the ice, while the other one which is a piece of insulation that looks like the aluminum... just barely melts some of the piece... This brings up many discussions about insulators and heat conductors...

Comments about Arbor Scientific Ice Melting Blocks:
It was even more than I expected!!! In just 20 minutes 6 ice cubes melted(one placed on the metal block at a time until it melted) to block that contained a composite where a single ice cube had not melted.

Comments about Arbor Scientific Ice Melting Blocks:
This demo is great because it requires students to do more than just watch it. When they feel how cold the aluminum plate is after the ice melts, they really develop a great understanding of what it means to *melt*. Simple and memorable.
