Title: Exploring States of Matter

Grade Level: Year 3

Objective: - Identify and describe the three states of matter: solid, liquid, and gas. - Understand the concept of changes in states of matter. - Differentiate between the three states of matter through hands-on activities and discussions. - Watch a video to reinforce understanding.

Materials: - Chart paper and markers - Various objects representing different states of matter (e.g., ice cube, water, balloon, clay, etc.) - Plastic cups - Ice cubes - Water - Balloons - Clay or playdough - Video: “States of Matter for Kids” (link: https://www.youtube.com/watch?v=5WLJoq1XKsM)

Procedure:

1. Introduction (10 minutes):
   • Begin the lesson by asking students if they know what matter is. Write their responses on the chart paper.
   • Explain that matter is anything that takes up space and has mass.
   • Introduce the concept of states of matter: solid, liquid, and gas.
   • Show examples of objects representing each state of matter (e.g., ice cube, water, balloon, clay) and ask students to identify the state of matter for each object.
2. Whole-Class Activity: Sorting States of Matter (15 minutes):
   • Divide the class into small groups.
   • Distribute plastic cups, ice cubes, water, balloons, and clay/playdough to each group.
   • Instruct students to observe and discuss the properties of each object and sort them into the appropriate state of matter category.
   • Circulate among the groups to provide guidance and support as needed.
   • After sorting, have each group share their findings with the class and explain their reasoning.
3. Differentiated Activity: States of Matter Collage (20 minutes):
   • Provide each student with a blank sheet of paper and art supplies (crayons, markers, colored pencils, etc.).
   • Instruct students to create a collage that represents the three states of matter.
   • Encourage students to be creative and use different colors and shapes to depict solids, liquids, and gases.
   • For students who need additional support, provide pre-cut pictures or shapes representing each state of matter that they can glue onto their collage.
4. Video: “States of Matter for Kids” (10 minutes):
   • Gather students in a comfortable viewing area and play the video “States of Matter for Kids.”
   • Encourage students to pay attention and take notes if necessary.
   • After watching the video, facilitate a brief discussion to reinforce key concepts and address any questions or misconceptions.
5. Conclusion and Reflection (5 minutes):
   • Review the main points covered in the lesson: the three states of matter (solid, liquid, and gas) and their properties.
   • Ask students to share one thing they learned or found interesting during the lesson.
   • Collect the collages for display or assessment purposes.

Extension Activity (Optional): - Conduct a simple experiment to demonstrate changes in states of matter, such as melting an ice cube or boiling water. Discuss the changes observed and relate them back to the concept of states of matter.

Note: The duration of each activity can be adjusted based on the specific needs and pace of the class.
