Evaporation and Condensation
Students will conduct simple experiments to observe and understand the processes of water turning into vapor and back into liquid.
Key Questions
- Explain how water disappears from a puddle on a sunny day.
- Analyze the conditions necessary for condensation to occur.
- Predict where water droplets will form on a cold glass.

About This Topic
Clay Techniques introduces 3rd Year students to the tactile world of ceramics. This topic is a core part of the NCCA Clay strand, where students move from simple play to purposeful construction. They learn the three fundamental hand-building methods: pinch pots, coils, and slabs. These techniques allow them to create everything from functional vessels to imaginative sculptures. Understanding the properties of clay, its weight, its moisture levels, and how it 'remembers' touch, is essential for success.
Students also explore the 'joining' process, learning the importance of 'slip and score' to ensure their pieces don't fall apart in the kiln. This topic is inherently hands-on and requires patience and problem-solving. It is an excellent opportunity for collaborative learning, as students can help each other troubleshoot structural issues. Students grasp this concept faster through structured discussion and peer explanation during the building process.
Active Learning Ideas
Peer Teaching: The Slip and Score Expert
After a brief demo, one student in each group is designated the 'Structural Engineer'. They must teach their peers the correct way to score and join two pieces of clay, checking everyone's work to ensure a strong bond.
Stations Rotation: Hand-Building Basics
Three stations are set up: one for making the perfect pinch pot, one for rolling even coils, and one for creating flat slabs. Students rotate through each, creating a small 'sample' of each technique to keep in their workspace.
Inquiry Circle: The Tallest Tower
In pairs, students are given a set amount of clay and must use a combination of coils and slabs to build the tallest stable structure they can. They must discuss and test different 'foundations' to see what supports the weight best.
Watch Out for These Misconceptions
Common MisconceptionYou can just stick two pieces of clay together like Play-Doh.
What to Teach Instead
Students often find their pieces falling off once dry. A 'stress test' activity where they try to pull apart joined pieces (one slipped/scored, one not) quickly demonstrates why the technical process is vital.
Common MisconceptionThicker clay is always stronger.
What to Teach Instead
Students often make very heavy, thick walls. By showing them how thick clay can crack or even explode in the kiln due to trapped air/moisture, they learn the value of even, controlled thickness.
