This activity may take several class periods.)
a CLEAR PLASTIC bottle, you can make your own ice core:
1. First, you will need a plastic bottle.
(A 20 ounce plastic soda bottle will do the trick. Just make sure
it is clean and dry before the activity!) Place some ice shavings
in your bottle. In your journal, be sure that you record the amount
of ice shavings (or snow) you place into your bottle. You may want
to record the level on your bottle with the date.
2. Freeze the bottle overnight. Allow your bottle
to thaw just a few minutes and record the height of the ice/snow.
Also, record any observations you make about the contents of your
bottle (your sample). You may want to draw a picture of your "ice
core," illustrating the observations you have made and labeling
important features. Add more snow to your bottle and refreeze overnight.
