Good-Bye Mrs. Hunter





Mrs. Laubscher's class was sad to see our WONDERFUL student teacher, Mrs. Hunter leave.  She is going to make an outstanding teacher next year and she will be missed.  We hope that she enjoys the classroom library that we started for her with our favorite books and messages from students inside the front cover! 


Coliseum Sketching




Come by the third grade hall to see our NEW Coliseum sketches. Our next unit of study will be ancient Rome. Notice the three different columns, Doric, Ionic and Corinthian, all influenced by ancient Greece.

Awesome Frost

Can you see the frost!?


We were curious about frost. Some of the questions we wondered were...

  • What is frost?
  • What is frost made out of?
  • What creates frost?
  • Is frost just frozen dew drops?
  • What is frost caused by?


We had lots of questions! We hoped that our experiment would help us find the answers to at least some of our burning questions. On top of a sheet of wet paper, we placed a can filled two-thirds of the way with ice and the rest with salt. We tried to figure out which of our materials represented different weather conditions outside that help make frost. We realized that the wet paper was like the wet ground outside, or the water vapor in the air. The can filled with ice represented cold air outside. (The salt in the can made the ice colder.) When the water vapor in the air around the can touched the freezing cold can, it slowed down and turned to frost! The same thing happens outside when the air is colder and the dew droplets turn into ice on your windshield or bedroom window.
