Unit: Exploring Matter Through Art

Lesson 1: Introduction to Matter

---

British Columbia Curriculum Alignment

Big Idea:

• Properties of materials determine their uses.
• Artistic expression is a method of understanding and communicating ideas about the natural world.

Curricular Competencies:

• Reasoning and Reflecting: Explore and express ideas using elements, principles, and concepts of art and design.
• Developing Skills: Experiment with materials, tools, and processes to create and communicate.
• Communicating and Documenting: Respond to and interpret artworks by considering personal and cultural perspectives.

Content:

• Explore different states of matter (solid, liquid, gas) through sensory experiences and visual arts.
• Learn properties and characteristics of matter in everyday life.

Learning Objectives

By the end of this lesson, students will be able to:

1. Identify and describe the three states of matter — solid, liquid, and gas.
2. Recognize the properties of each state through visual and tactile examples.
3. Use images and collage techniques to represent each state creatively.
4. Develop teamwork and communication skills during group discussion.

---

Materials

• Large chart paper or whiteboard
• Projector or printed images showing examples of solids, liquids, and gases in everyday contexts (e.g., ice cube, water, steam)
• Safety scissors (enough for each pair or group)
• Glue sticks
• Assorted magazines, printed pictures, and coloured paper for collage (ensure images depict solids, liquids, gases)
• Construction paper (one per student for final collage base)
• Markers and coloured pencils (for labelling and decorating)

Lesson Sequence

1. Introduction and Engagement (10 minutes)

• Begin by asking: “What is matter?” Collect ideas from students and write them on the board. Guide the conversation gently towards the concept that everything around us is made of matter — things we can see and touch.
• Show simple, colourful images or a digital slideshow of solids (ice, rock), liquids (water, juice), and gases (steam, clouds).
• Briefly explain the characteristics of each state, using age-appropriate language:
  • Solid: Keeps its shape, you can hold it.
  • Liquid: Flows, takes the shape of its container.
  • Gas: Invisible or see-through, spreads out into the air.
• Use a quick tangible demonstration — for example, hold an ice cube, pour water, and blow lightly on the back of your hand to feel air flow.

2. Group Discussion – Identifying Matter (5 minutes)

• In small groups (4-5 students), have pupils discuss everyday things they know that are solids, liquids, or gases.
• Each group shares one example aloud with the class to build collective understanding.

3. Collage Creation: Representing States of Matter (25 minutes)

• Hand out construction paper as a base for collages. Divide the page into three sections labelled “Solid,” “Liquid,” and “Gas.”
• Explain the task: using scissors and glue, students will cut out images from magazines or printed pictures that represent each state of matter. Encourage creativity — some students might draw small additions or decorations with markers after gluing.
• Circulate the classroom, providing support and encouraging students to think about why their chosen images fit the specific state of matter.

4. Sharing and Reflection (5 minutes)

• Invite a few students to share their finished collages with the class, explaining their image choices.
• Ask reflective questions:
  • Why did you put this picture in the “gas” section?
  • What makes a liquid different from a solid in your collage?
• Affirm all contributions to build confidence.

Assessment

• Formative Observation:
  • Monitor participation in the group discussion to assess understanding of states of matter.
  • Observe students’ ability to select appropriate images for each matter state during collage activity.
• Student Self-Assessment:
  • Use a simple thumbs-up/thumbs-down for understanding at lesson closure: “Do you feel you can now tell the difference between a solid, liquid, and gas?”
• Teacher Feedback:
  • Provide positive, specific feedback during sharing, highlighting correct matter classifications and creative expression.

Differentiation & Extensions

• Support: Provide pre-cut images for students who struggle with scissors or fine motor skills. Pair ELL students with buddies and use visual clues to support vocabulary learning.
• Enrichment: Encourage curious students to add facts about how matter changes states (e.g., ice melts into water) which can be explored in future lessons.

Cross-Curricular Connections

• Science: Introduction to physical properties of materials (Science 3 – Matter and Energy)
• Language Arts: Vocabulary development (solid, liquid, gas) and speaking/listening during group discussion
• Personal Awareness and Responsibility: Collaborative skills, sharing materials respectfully

---

Teacher’s Notes:

• Prepare images ahead of time to represent all three states clearly and recognisably for diverse learners.
• Consider capturing photos of student collages to document learning throughout the unit.
• Keep energy high with visually stimulating materials and encourage language use linking art and science concepts.

This introductory lesson creates a memorable sensory and visual experience linking art and science, setting a strong foundation for further exploration of matter in future lessons.
