Reflection: Lesson Planning Ice Cores: Gathering Data - Section 4: Explore

 

You will want to practice the process of making the ice core first before teaching this lesson. Here are few tips I found helpful. 

  • Add more sand to the global events. Too little sand and you will have difficulty seeing them. 
  • Keep the layers thick. They will compact when you core them and compress. 
  • Try freezing the "ice sheets" over night then core the next day. The dough won't completely harden and will fill more of the coring tube.
  • For coring tubes I used plastic test tubes that I cut the bottoms off of using a hacksaw. If you do not have plastic test tubes look for something similar that is clear and around 3/4" - 1" diameter.  
  • If you use salt, you must core on the SAME DAY. In one of my classes we ran out of time to core and waited a day. The salt layer "disappeared" overnight. The salt dissolved into the dough. Alternatively, take the salt out and substitute sand.
