Grade 4 The Water Cycle Lesson Plan

Learning Objectives

• Students will be able to name and describe the four main stages of the water cycle: evaporation, condensation, precipitation, and collection.
• Students will be able to explain the role of the sun in driving the water cycle.
• Students will be able to describe how the water cycle connects to wet and dry seasons in their own region.
• Students will be able to draw and label a simple diagram of the water cycle.

Lesson Procedure

• Read through the lesson procedure before class and gather the simple materials for the Mini Water Cycle in a Bag demonstration (a clear resealable bag, a little water, and tape). Teach the six steps in sequence, drawing the water cycle diagram on the board as described and setting up the bag demonstration partway through the lesson so it has time to work over the following days. Distribute the Water Cycle Diagram Labeling Worksheet for guided and independent practice, then use the closing discussion as a quick check before moving on to the Mini Water Cycle in a Bag observation activity later in the week.

Assessment

Use the completed Water Cycle Diagram Labeling Worksheet as a formative check during the lesson, and observe students during guided and independent practice using the criteria in the Water Cycle Grading Rubric. The quiz and the Mini Water Cycle in a Bag observation activity can be used later in the week as follow-up checks of understanding.

Differentiation

Support: Provide a picture word bank showing the sun, a cloud, rain, and a river next to the words evaporation, condensation, precipitation, and collection. Offer sentence frames such as "The sun heats the water and it ___." Pair English language learners with a supportive partner and reduce the diagram to the four main stages only.
On-level: Students complete the full worksheet independently, labelling all parts of the diagram and describing each stage in a full sentence.
Challenge: Students add the word transpiration to their diagram and explain where it fits in the cycle, or explain in writing why some places have a rainy season and a dry season using the water cycle to support their answer.

Classroom Activity Ideas

• "Be the Water Droplet" — set up four stations around the room labelled Ocean, Cloud, Rain, and River. Students move from station to station acting out the journey of a water droplet, saying the name of each stage out loud as they arrive before moving to the next station.

Teacher Tips

Set up the Mini Water Cycle in a Bag demonstration as early in the lesson as you can manage — even a few extra hours of sun before students check it the next day makes the first observation far more convincing.
