Lesson Plan Description
Lesson Plan Description
This unit challenges students to solve the mystery of disappearing water. Students discover how everyday evaporation is taking place around us and water is changing into vapor at varying rates from all open water bodies (and living organisms) depending on the sun’s heat. This evaporated water falls right back to earth in the form of rain, hail, or snow. Students develop an understanding of the role evaporation plays in our daily life.
