Properties of Solids
Students will observe and describe the distinct properties of various solid materials, focusing on shape, volume, and rigidity.
Key Questions
- Differentiate between various solid objects based on their observable properties.
- Analyze how the arrangement of particles contributes to a solid's fixed shape.
- Predict how a solid's properties might change under extreme pressure.

About This Topic
Relief printing in 4th Class introduces students to the concept of the 'multiple.' Unlike a painting, which is a unique object, a print can be reproduced many times. This topic focuses on creating a 'matrix' or block, using soft foam or lino, and exploring how repeating an image creates pattern, symmetry, and tessellation. Students learn to think in reverse, as the printed image is a mirror of the carved block, and they must consider 'negative space' (the areas they cut away) as much as the 'positive' lines.
This aligns with the NCCA 'Print' strand and integrates heavily with mathematical concepts of transformation and tiling. Students develop a sense of rhythm and sequence as they experiment with different ink colors and paper layouts. This topic comes alive when students can engage in 'collaborative printing,' where individual blocks are combined to create a large-scale classroom tapestry or wallpaper design.
Active Learning Ideas
Stations Rotation: The Print Lab
Set up stations for 'Inking,' 'Pressing,' and 'Drying.' Students move through the process in a production line, learning the importance of the right amount of ink (the 'velcro' sound) and even pressure to get a clean print.
Inquiry Circle: Tessellation Tiling
Each student creates a square foam block with a simple geometric design. They then work in groups to see how many different patterns they can create by rotating and repeating their blocks on a long roll of paper.
Think-Pair-Share: The Mirror Challenge
Students draw a simple letter or shape on a small mirror using a dry-erase marker. They then look at the reflection and try to draw the 'reverse' on their printing block. They discuss with a partner why certain shapes (like 'S' or 'R') are harder to reverse than others.
Watch Out for These Misconceptions
Common MisconceptionStudents often forget that their print will be a mirror image of their block.
What to Teach Instead
Use mirrors throughout the design phase. Have students hold their sketches up to a mirror to see how they will look when printed. This active 'pre-visualization' helps them correct letters or directional designs before they start cutting.
Common MisconceptionChildren frequently use too much ink, which fills in the fine details of their design.
What to Teach Instead
Teach them to listen for the 'hiss' or 'velcro' sound of the roller. If it's squelchy, it's too much. A hands-on 'ink-off' competition to see who can get the thinnest, most even layer of ink helps them master the technical control of the brayer.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
