Matter Mania: Exploring Physical and Chemical Changes!
Lesson Description
Video Resource
Key Concepts
- Matter: Everything around us that takes up space.
- Physical Change: A change in matter that doesn't change what the matter is made of.
- Chemical Change: A change in matter that creates a new substance.
Learning Objectives
- Students will be able to define matter and provide examples.
- Students will be able to differentiate between physical and chemical changes.
- Students will be able to identify examples of physical and chemical changes in everyday life.
Educator Instructions
- Introduction (5 mins)
Begin by asking students what they think matter is. Show various objects (pencil, water bottle, etc.) and ask if they are matter. Introduce the concept of physical and chemical changes as ways matter can change. - Video Viewing (7 mins)
Play the 'Physical and Chemical Changes for Kids' video from Homeschool Pop. Encourage students to take notes on examples of physical and chemical changes presented in the video. - Guided Discussion (10 mins)
After the video, lead a discussion about the key concepts. Clarify any misunderstandings and reinforce the differences between physical and chemical changes. Use the examples from the video (pie, logs, gate, marshmallow) to prompt discussion. - Activity: Change Detective (15 mins)
Divide students into small groups. Provide each group with a set of everyday objects and scenarios (e.g., cutting paper, melting ice, burning a candle, mixing baking soda and vinegar). Have them identify whether each scenario represents a physical or chemical change and explain their reasoning. Each group can present their findings to the class. - Wrap-up and Assessment (8 mins)
Review the key concepts and learning objectives. Administer the multiple-choice and fill-in-the-blank quizzes to assess student understanding.
