Reflection: Problem-based Approaches Water Cycle Models - Section 4: Elaborate

 

This model requires a heat source in order to produce evaporation.  The largest source of heat in our classroom is the radiator.  I place the buckets on top of them, thinking evaporation would occur rather quickly as the radiator is unbearably hot to the touch.  I was wrong. This process took well over 30 minutes to occur.  I propose 2 solutions: 1- make the model using glass containers and hotplates, or 2- preparing a second activity regarding the water cycle while the water is being heated.

Water Cycle Models

Unit 8: Earth's Atmosphere and Weather
Lesson 2 of 15

Objective: SWBAT create a model of the water cycle and explain its benefits and limitations of explaining the water cycle.

Big Idea: By creating a physical model of the water cycle, students will gain a kinesthetic understanding of the phase changes that occur throughout the cycle.
