Elementary School Science

Input:
What is the most important content in this lesson?
To reach this lesson’s objective, students need to understand:

• The definitions to the terms: evaporation and condensation.

• The process of evaporation.

• How the temperature influences the rate of evaporation.

​

How will the learning of this content be facilitated?

• The teacher should begin class by inviting all of the students to stand around a table. The teacher should show the students the plastic cup and cup of water. Starting at the cup, the teacher should draw three horizontal lines (one underneath the other, about ½ inch apart). The teacher should explain to the students that today they will be doing an experiment about evaporation. The teacher should pour the water into the cup and then place the cup on a window ledge or some place that is in direct sunlight. The teacher should give each student a “What Will Happen to the Water?” worksheet and instruct them to go back to their seats. The teacher should allow the students about 5 minutes to complete the worksheet, predicting what they think will happen to the water by the end of class. Once the students are done, the teacher should review some of the responses. The responses should be recorded on the blackboard or chart paper. At the end of class, the teacher and students will revisit this experiment.

​

• After the activity discussion is done, the teacher will begin presenting the information on weather. If it is possible, project each page of the teacher’s copy of the “All About Weather” Science Journal worksheet onto the board using a projector or put into a PowerPoint document and project.  The teacher’s copy of the journal has certain words/phrases that are bolded red and highlighted. It is important the teacher explain to the students those words/phrases are to be highlighted in their (students) journal. For this lesson, the teacher should review these pages:

• Page 16: The Water Cycle

** This page reviews the water cycle**

Optional Video: Water: Water Cycle, Forms of Water and Water Conservation- Something Fishy: Kids Lesson 1” (Source: https://www.youtube.com/watch?v=TTkFHO2-jsc&t=231s ) This video can be used to clarify the water cycle to the students**

• Pages 17-18: Evaporation and Condensation

**This page reviews evaporation and condensation and the roles each plays in terms of weather**

• Pages 19: Rain, Dew, and Fog: What is the Difference?

**This page reviews the differences between rain, dew, and fog**

​

• After the information has been presented, the teacher should show the video YouTube Video: “Eureka 18- Evaporation and Condensation” by Sheila Tjapkes. The video, which is about 5 minutes long, is a cartoon that explain evaporation and condensation. Before starting the video, the teacher should hand out the “Did You Know?” worksheet. The students need to write down three facts that they learned from the video. After the video is over, the teacher should begin a discussion about the content. Any misconceptions about the content presented should be cleared up at this point.

​

• Closure

  • For the closure, the teacher should revisit the experiment from the beginning of class. Again, the teacher should gather the students around the table and place the plastic cup in the center. The teacher and the students should observe the cup and see at which line the water is at. The teacher and students should discuss the predictions that were made at the beginning of class.

  • Finally, the students should answer work on the worksheet “What Happened To the Water?”
