Lesson Note: Rock Cycle

Grade Level: 4th Grade Subject: Science

Objective: - Students will understand the concept of the rock cycle and how rocks are formed, transformed, and recycled over time. - Students will be able to identify and describe the three main types of rocks: igneous, sedimentary, and metamorphic. - Students will be able to explain the processes involved in the rock cycle.

Materials: - Chart paper or whiteboard - Markers or chalk - Rock samples (igneous, sedimentary, and metamorphic) - Magnifying glasses - Rock cycle diagram handout (one per student) - Pencils or pens

Procedure:

1. Introduction (5 minutes): - Begin the lesson by asking students if they have ever wondered how rocks are formed or why they look different from one another. - Show them different rock samples and ask them to describe the differences they observe. - Explain that rocks go through a continuous process called the rock cycle, where they are formed, transformed, and recycled over time.

2. Rock Cycle Discussion (10 minutes): - Write the term “rock cycle” on the chart paper or whiteboard. - Ask students if they have any ideas about what the rock cycle might be. - Explain that the rock cycle is a continuous process that involves the formation, transformation, and recycling of rocks. - Discuss the three main types of rocks: igneous, sedimentary, and metamorphic. - Explain that igneous rocks are formed from the cooling and solidification of molten rock (magma or lava), sedimentary rocks are formed from the accumulation and compaction of sediments, and metamorphic rocks are formed from the transformation of existing rocks under high heat and pressure.

3. Rock Cycle Diagram Activity (15 minutes): - Distribute the rock cycle diagram handout to each student. - Instruct students to carefully observe the diagram and label the different processes and types of rocks involved in the rock cycle. - Encourage students to use the rock samples and magnifying glasses to examine the different rocks closely. - Circulate around the classroom to provide assistance and answer any questions.

4. Group Discussion (10 minutes): - Bring the students back together as a group and discuss their findings from the rock cycle diagram activity. - Ask students to share their labeled diagrams and explain the processes involved in the rock cycle. - Encourage students to ask questions and engage in a discussion about the topic.

5. Conclusion (5 minutes): - Summarize the main points of the lesson, emphasizing the three types of rocks and the processes involved in the rock cycle. - Ask students to reflect on what they have learned and how it relates to the rocks they see in their everyday lives. - Provide an opportunity for students to ask any final questions or share any additional thoughts.

Assessment: - Observe students’ participation and engagement during the group discussion. - Review students’ labeled rock cycle diagrams for accuracy and understanding. - Ask students to write a short paragraph explaining the rock cycle in their own words as a formative assessment.
