1. Collecting clay and making it wet.
2. Adding enough water to get the right consistency.
3. Pounding and kneading the clay to make it like dough.

Q3: What would happen if there were no patterns in nature?

Q2: Find out how some commonly used objects like pencils, erasers, pens, and notebooks are made. Ask your elders.
Ans: Pencils are made from wood and graphite. The wood is cut into slats, grooved to hold the graphite, glued together, and then shaped into pencils. Erasers are made from rubber or synthetic materials and are attached to the pencil ends. Pens are made from plastic or metal and contain an ink reservoir and a writing tip. Notebooks are made from paper sheets bound together, often with a cardboard cover.
