Lesson Plan for Year 4 - Science - States of Matter

### Lesson Plan: States of Matter **Grade Level**: 4 **Subject**: Science **Duration**: 60 minutes **Topic**: States of Matter --- ### Objective: 1. Students will be able to define matter. 2. Students will identify and describe the three common states of matter: solid, liquid, and gas. 3. Students will understand how matter can change from one state to another. ### Materials: - Whiteboard and markers - Chart paper and markers - Balloons (filled with air) - Ice cubes - Water (room temperature and hot) - Clear plastic cups - Kettle or hotplate for boiling water - Thermometer - Worksheets - Science journals ### Standards: - Next Generation Science Standards (NGSS): 4-PS3-2, 4-PS3-4 - Common Core Standards for English Language Arts: CCSS.ELA-LITERACY.SL.4.1 --- ### Lesson Structure: #### Introduction (10 minutes) 1. **Hook**: Begin with a simple demonstration using the ice cubes. Ask students what will happen if you leave the ice cubes on the table for a while. 2. **Discussion**: Have students share their predictions. Explain that this lesson will explore different states of matter and how they change. #### Direct Instruction (15 minutes) 1. **Define Matter**: Matter is anything that takes up space and has mass. 2. **States of Matter**: - **Solid**: Has a definite shape and volume. Particles are closely packed in a fixed position. (e.g., ice cube) - **Liquid**: Has a definite volume, but takes the shape of its container. Particles are close but can move/slide past each other. (e.g., water) - **Gas**: Has no fixed shape or volume. Particles are far apart and move freely. (e.g., air in a balloon) 3. **State Changes**: - **Melting**: Solid to liquid (e.g., ice melting) - **Freezing**: Liquid to solid (e.g., water freezing) - **Evaporation**: Liquid to gas (e.g., water boiling) - **Condensation**: Gas to liquid (e.g., steam turning back to water) #### Guided Practice (10 minutes) 1. **Activity: Observing State Changes**: - **Ice Melting**: Place an ice cube in a clear plastic cup and observe changes over time. - **Water Evaporation**: Show a boiled kettle with steam and observe the condensation on a cooler surface (like a metal lid). 2. **Worksheet**: Distribute worksheets where students match states of matter with descriptions and examples. #### Independent Practice (15 minutes) 1. **Group Activity**: - Divide the class into small groups. - Provide each group with ice cubes, room temperature water, and a balloon with air. - Have them observe, discuss, and record the properties (solid, liquid, gas) in their science journals. - Encourage students to draw and label the molecules in each state. #### Assessment (5 minutes) 1. **Quick Quiz**: Have students take a 5-question quiz on states of matter to assess their understanding. 2. **Exit Ticket**: Ask students to write one thing they learned about states of matter and one question they still have. #### Closure (5 minutes) 1. **Review**: - Summarize the key points about states of matter. - Answer any remaining questions. 2. **Preview Next Lesson**: Introduce the concept of mixed states, such as how clouds are both liquid droplets and gas. ### Homework: Assign a simple task where students find examples of solids, liquids, and gases at home and describe them in their science journal. --- ### Differentiation: 1. **For Advanced Students**: Provide additional resources on less common states of matter, like plasma. 2. **For Struggling Students**: Offer extra visual aids, like videos demonstrating state changes, and provide one-on-one support. --- ### Reflection: After the lesson, reflect on what worked well and what might need adjustment for future lessons. Consider student engagement, understanding, and whether the objectives were met. --- This lesson provides a balanced approach to teaching states of matter with both theoretical and practical elements to engage fourth-grade students.
