Lesson 1: Identification of Materials
Duration of Days: 2
Lesson Objective
Students will be able to identify and label six core construction materials (concrete, masonry, glass, plastic, wood, and metal) based on their physical characteristics and differentiate between their primary purposes in the built environment.
What specific materials make up the world around us?
How is the classification of anything helpful when learning about something new?
How does the appearance of a material hint at its function?
Concrete: A composite structural material.
Masonry: Construction using individual units like bricks or stone laid in mortar.
Glass: A transparent solid material used for openings.
Plastic: Synthetic or semi-synthetic organic compounds.
Natural Materials (Wood): Cellular organic material derived from trees.
Metal: Pure metals or alloys used for structural or electrical purposes.
HS-PS2-6: Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.
Technical reading and evidence-based observation; students must accurately label technical images with specific terminology.
Description:
Day 1: Students engage in an interactive lecture using "Overview of Types of Construction Material" slides to learn the visual cues for identifying core materials. The teacher presents example slides showing concrete supports, metal door frames, and metal piping to model the identification process.
Day 2: Students conduct a Material Scavenger Hunt. Using smartphones or cameras, they must locate and photograph three different interior parts (e.g., ceiling, door frame, floor) and two different exterior parts (e.g., foundations, sidings) of a building. They then compile these into a digital portfolio, correctly labeling each of the six required material types.
Purpose: To ground the Science of Construction in immediate, real-world observation and establish a framework for classifying structural, insulating, and finishing materials.
DOK Level: 2 (Classify and Apply).
Real-World: Students identify the materials they interact with daily, such as the metal door frames they walk through or the concrete structural supports holding up their classroom.
Culturally Relevant Connections: Discussion on how local school and community architecture reflects regional material availability and building standards.
Students may assume all "stone-like" materials are concrete, failing to distinguish between natural stone and manufactured masonry units like Concrete Masonry Units (CMUs).
Visual Learners: Use high-resolution images and "Material Information Cards" to show clear examples of textures.
Hands-on Learners: Provide physical samples of wood, metal, and brick for tactile comparison.
Struggling Learners: Provide a simplified identification checklist with labeled diagrams.
Demonstration of Learning: Submission of a labeled photo portfolio featuring six original images.
Knowledge Check: A General Overview MCQ on classification criteria (Structural vs. Finishing).
