Making Things
Official NCERT chapter from Our Wondrous World (book code ceev1). ExamMaster notes are original teaching at CBSE Class 3 depth.
This lesson follows the official chapter “Making Things” in Our Wondrous World. The words below are ExamMaster’s teaching, not a paste from the book. Use the NCERT chapter for the classroom sequence; use these notes to hold the idea without copying exercises or figures.
- CBSE Class 3
- Easy level
- 8 concepts
1A pot, a kulhad, and a gullak are objects made from a material
Each is an object. Clay is a common material. The names are uses (drink, sip, save coins), not the material-word.
Three names do not mean three materials.
Figure. Three names are three uses — hold water, sip, save coins. The material-word under all three can still be clay. Count objects and material separately.
How it works
- Point to the objectPot, kulhad, or gullak.
- Name the materialOften clay.
- Name the use separatelyHold water, sip, save.
2Clay can be shaped; that is a change you can reverse until it is fired
Wet clay can become a ball, then a pot, then a ball again — until it is dried hard or fired. After firing, you cannot honestly squash it back.
Reversible here means you can undo the shape while it is still soft.
Figure. Wet clay can go lump to pot and pot to lump. After firing, the squash-back arrow is gone. Reversible means you can still undo the shape.
How it works
- Start with soft clayA lump.
- Shape itPot.
- Ask if you can squash it backIf yes, not fired yet.
3A maker follows steps: shape, dry, bake or paint
Steps have an order. Paint before the shape exists is a miss. Dry before a wet collapse if the maker needs a firm form.
Skipping “shape” and jumping to “pot existed” hides the making.
Figure. A maker’s steps have an order: shape, then dry, then bake or paint. Paint before a form exists is a miss. The picture is a chain, not three names in a bag.
How it works
- Shape firstThe form.
- DryWater leaves.
- Bake or paint if that maker doesLater steps.
4The material is not the object
Clay in a bag is material. The pot is the object after making. Buying clay is not buying a pot.
This is the same split as the last chapter, now inside a making-story.
Figure. Clay in a bag is material. The pot is the object after making. Buying clay is not buying a pot — making is the arrow that changes the word.
How it works
- Point to the bag of clayMaterial.
- Point to the finished potObject.
- Do not swap the wordsMaking turns material into object.
5A property you can test after making: holds water or not
Pour a little water. If it holds, that pot passed a hold-test. An unfired pinch-pot may fail.
The test is pour, not a sales story.
Figure. The hold-test is a pour, not a sales story. A leaks; B keeps the water inside. Only B passes.
How it works
- Pour a littleOne test.
- Watch leak or holdEvidence.
- Name pass or failHolds water, or not.
Hold-test after making
Two pinch-pots: A leaks in 10 seconds; B holds a cup of water for a minute. Which passed the hold-test?
- ALeaks
- BHolds
- PassB
Pro tip. Pour is the test. Time to leak is evidence, not a slogan.
6Hands and tools are causes; the pot is the change
Fingers, a paddle, or a wheel cause the shape-change. The pot is what changed into. Cause and change stay two words.
The pot did not “make itself”.
Figure. Hands or a wheel are causes. The pot is what the lump changed into. The pot did not make itself — making has a before.
How it works
- Name the causeHands or tool.
- Name the changeLump → pot.
- Keep “it always was a pot” outMaking has a before.
7One kitchen or craft case
One kulhad at a stall, or one dough ball becoming a roti, is enough. Dough is another shape-story: heat sets it.
You do not need every craft of the country.
Figure. One dough ball becoming a roti is enough. Heat sets the shape, the way firing sets clay. You do not need every craft in the country.
How it works
- Pick one makingClay pot, or roti.
- List before and afterLump → object.
- Name one stepShape, or heat.
8A miss: thinking the pot always existed
If the pot always existed, there was no making. The miss is skipping the before.
Ask “what was it before?” Soft clay, or dough, is an honest before.
Figure. If the pot always existed, there was no making. The miss is skipping the before. Soft clay or dough is an honest before; the pot is the after.
How it works
- Ask for a beforeLump, clay, dough.
- Ask for an afterPot, roti.
- If someone says “always a pot”, call the missMaking needs a before.
Wet clay shaped into a pot, still soft, can often
- Be squashed back — not fired yet
- Never change again
- Be a steel spoon
Soft clay’s shape-change can still reverse.
Notes
- Mapped to the official NCERT chapter “Making Things”. Original teaching only — no textbook sentences.
- Science here is Physics, Chemistry and Biology ideas at this class, never a language or social-science chapter.
