Lesson Plan : CONDENSATION - THE WATER CYCLE

Teacher Name:
 MR SM MOAGI
Grade:
 Grade 7-8
Subject:
 Science

Topic:
 CONDENSATION
Content:
 Water on earth is used over and over. The water cycle, the continuous movement of water from ocean to air and land then back to the ocean in a cyclic pattern, is a central concept in meteorology. In the water cycle, the sun heats the Earth's surface water, causing that surface water to evaporate (gas). This water vapor then rises into the earth's atmosphere where it cools and condenses into liquid droplets. These droplets combine and grow until they become too heavy and fall to the earth as precipitation (liquid if rain, solid if snow). Water is temporarily stored in lakes, glaciers, underground, or living organisms. The water can move from these places by streams and rivers, returns to the oceans, is used by plants or animals or is evaporated directly back into the atmosphere.
Goals:
 Understand that water on earth moves in a continuous cycle. Be able to name and condensation explain the stages of the water cycle.
Materials:
  A clean, clear 2 liter plastic bottle for every 3 students A box of wood matches for every 3 students A thermometer for every bottle (available at fish stores) An eye dropper or other container for water A clean, clear 2 liter plastic bottle for every 3 students A box of wood matches for every 3 students A thermometer for every bottle (available at fish stores) An eye dropper or other container for water A clean, clear 2 liter plastic bottle for every 3 students A box of wood matches for every 3 students A thermometer for every bottle (available at fish stores) An eye dropper or other container for water
Introduction:
 Water on earth is used over and over. The water cycle, the continuous movement of water from ocean to air and land then back to the ocean in a cyclic pattern, is a central concept in meteorology. In the water cycle, the sun heats the Earth's surface water, causing that surface water to evaporate (gas). This water vapor then rises into the earth's atmosphere where it cools and condenses into liquid droplets. These droplets combine and grow until they become too heavy and fall to the earth as precipitation (liquid if rain, solid if snow). Water is temporarily stored in lakes, glaciers, underground, or living organisms. The water can move from these places by streams and rivers, returns to the oceans, is used by plants or animals or is evaporated directly back into the atmosphere.
Development:
 Overview of the Module In this module, students will first carry out a number of activities that demonstrate the concepts of condensation. The students will then construct a terrarium as a way to observe the water cycle as a whole. Immediately following this, students will use the I
Practice:
 TEACHER PREPARATION OF ACTIVITIES Students will begin the activities after the introduction to the lesson which asks them to think about if the water they drink is the same water dinosaurs drank. Each activity should begin with some opening questions, which should be discussed with the whole, class, and conclude with a set of questions that students will answer in writing.
Checking For Understanding:
 Assessment Assessment will be carried out throughout the lesson in the form of discussions and the written responses to the various activities. The final assessment will be to have each student answer the following question: where does condensation fit in water cycle water come from and where does it go? written/oral
Closure:
 LEARNERS MUST READ ABOUT EVAPORATION FOR THE NEXT LESSON
