Lesson Plan: Soluble and Insoluble
Grade: Senior KG (4-5 years old)
Introduction: - Begin the lesson by gathering the students in a circle and asking them if they know what happens when they mix water with different things. - Show them a glass of water and ask if they think everything can dissolve in water. - Explain that today, they will learn about things that can dissolve in water (soluble) and things that cannot dissolve in water (insoluble).
Lesson Outline: 1. Engage: (5 minutes) - Show a video clip (link: https://www.youtube.com/watch?v=3b3hZLXgXyM) that introduces the concept of soluble and insoluble to the students. - Ask the students to pay attention to what happens when different things are mixed with water.
- Explore: (10 minutes)
- Provide each student with a small cup of water and a variety of materials such as sugar, salt, sand, and pebbles.
- Ask the students to predict which materials will dissolve in water and which will not.
- Encourage them to test their predictions by adding each material to their cup of water and observing what happens.
- As they experiment, walk around the classroom to facilitate their exploration and engage in discussions about their observations.
- Explain: (10 minutes)
- Gather the students back in the circle and discuss their findings.
- Explain that materials that dissolve in water are called soluble, and materials that do not dissolve are called insoluble.
- Show them examples of soluble and insoluble materials, such as sugar, salt, sand, and pebbles.
- Discuss why some materials dissolve in water (e.g., sugar and salt are made up of tiny particles that spread out in water) and why others do not (e.g., sand and pebbles are made up of larger particles that do not mix with water).
- Elaborate: (10 minutes)
- Distribute a worksheet (link: https://www.teacherspayteachers.com/Product/Soluble-and-Insoluble-Worksheet-4781237) to each student.
- The worksheet should include pictures of various materials, and the students need to circle whether each material is soluble or insoluble.
- Walk around the classroom to provide assistance and guidance as needed.
Questioning: - During the lesson, ask questions to encourage critical thinking and assess understanding, such as: 1. What does it mean if something is soluble? 2. Can you give an example of something that is soluble? 3. Why do you think sand does not dissolve in water? 4. How can we find out if something is soluble or insoluble?
Assessment: - Informally assess the students’ understanding throughout the lesson by observing their participation, engagement, and responses to questions. - Use the completed worksheet to assess their ability to identify soluble and insoluble materials correctly.
Differentiation: - For students who need additional support, provide visual aids or real-life examples to help them understand the concept better. - For students who grasp the concept quickly, encourage them to think of other examples of soluble and insoluble materials and explain why they fall into each category.
Plenary: - Recap the lesson by asking the students to share one thing they learned about soluble and insoluble materials. - Show a short video clip (link: https://www.youtube.com/watch?v=3b3hZLXgXyM) summarizing the concept of soluble and insoluble for reinforcement. - Thank the students for their participation and encourage them to explore more about the topic at home.
