These experiments can be done year round, regardless of climate. If you live in a cold area these experiments can be done outdoors with an ideal operating temperature between -5 Celsius and -15 Celsius. If the temperature outside remains above freezing - the ice sample can be created in the freezer compartment of your refrigerator.

 

1. Obtain ice sample in the form of ice cubes or from a frozen bucket or other container.
2. Use a hand saw to cut a slice several centimeters in thickness. Or if the sample is small to begin with - proceed to step 3 below. If you are working in a warm climate create the ice sample in a container that is the desired dimension so that you can proceed directly to the thinning step (3).
3. On low heat - slowly melt the ice until you have a thin slice (a few millimeters thick). With a thin slab the process of thinning is straightforward. When thinning an irregular piece of ice - create one level side on the heating surface and then flip the slab over and create another flat and parallel surface. Continue to thin the ice until it is at the desired thickness.
4. When the slab is a few millimeters thick - place it onto the surface of a warmed glass sheet to cause some melting and store in a freezer to bond the ice to the glass. This will ensure that the sample will be easier to handle and that the ice will melt slower once removed from the freezer.
5. Place a polarizer sheet on a light table. Take the thin ice section out of the freezer and place it on the polarizer sheet. Place a second polarizer sheet on top of the ice and observe the patterns. Rotate the top polarizer sheet alter the appearence of color and ice texture.
6. Observe and photograph the results
