Objectives
|
Recognize the roles of condensation and evaporation in the water cycle. Relate
water cycle to different ecosystems
|
Standards Addressed
|
Learning about the water cycle, evaporation and condensation |
|
Hot plate, frying pans, ice and gloves for protection
|
Time Requirement
|
50 minutes |
Procedure/ Outline
|
Discuss the properties of the 3 major climates: Polar, Temperate and Tropical.
Discuss the water cycle. Heat one pan of water on the hot plate. When water
vapor is rising from the boiling water hold the other pan of ice cubes above the
hot pan using gloves to observe the condensation and precipitation
|
Modifications /Adaptions/ Extensions
|
Record the mass of ice cubes (any quantity) and store them for two weeks in a
freezer, check the mass for evidence of sublimation |
Assessment
|
Students will draw a model of the water cycle of describe the water cycle based
upon this demonstration
