This lesson follows the official chapter “Diversity in the Living World” in Curiosity. 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 6
- Easy level
- 8 concepts
1Diversity in Plants and Animals Around Us
Diversity means living things around you are not all the same: stems, leaves, legs, wings. You notice differences you can point to.
A list of distant names with no pointed difference is not this look.
Figure. Living names jobs: take or make food, grow, respond. A toy dog can look alive and still fail every job.
How it works
- Point to two living thingsThis plant, this insect.
- Name one difference you can seeStem, leaf, legs…
- Call that a local diversity recordOne place.
2How to group plants?
Group by a test: herb / shrub / tree by stem and height; or herbs versus woody; or where they live. Name the test before you sort.
Grouping by “pretty flower” is not a plant-group test unless the task asks colour.
Figure. Herbs, shrubs, and trees are a height grouping. The boxes are relative height, not measured metres.
How it works
- Pick one testStem feel, height, habitat.
- Run it on each plant you haveThis one.
- Put it in that groupThe sort.
3How to group animals?
Group by a test you can run: how it moves, where it lives, backbone you are not required to invent — stay with looks and habits you can see or were given.
Cute versus useful is not the grouping test.
Figure. Class 6 groups animals by a job you can point to — walk, fly, or swim — not by cute names.
How it works
- Pick a testWalk, fly, swim; land or water.
- Run itThis animal.
- SortSame test, same group.
4Plants and Animals in Different Surroundings
A desert plant and a pond plant pass different place-tests. The surrounding is the habitat; the living thing has jobs that fit or fail there.
Moving a pond plant to a story-desert without a reason is a cartoon.
Figure. Land and water are two surroundings. The living thing still has to eat, grow, and respond in that place.
How it works
- Name the surroundingPond, desert, tree shade.
- Name a feature that fits that placeIf you can point to it.
- Keep place and feature as a pairHabitat + job.
5Height and stem are two grouping tests
A herb is often small with a soft stem; a tree is tall with a thick woody stem. Those are two tests you can attempt on the plant in front of you.
A drawing of a rose is not the roadside weed.
Figure. Two school tests: how tall, and is the stem soft or woody. One test alone is not the grouping.
How it works
- Look at heightOne test.
- Feel or see the stemSoft or woody.
- Group by those, not by a remembered pictureThis plant.
6Venation and roots can travel together
Many plants with netted (reticulate) leaf veins have tap roots; many with parallel veins have fibrous roots. “Can travel together” means a pattern you may check — not a law you invent for every plant today.
If you cannot see the root, do not fake the pair.
Figure. Reticulate veins often sit with a tap root; parallel veins often sit with fibrous roots. The pair is the grouping, not a drawing of a leaf.
How it works
- See the leaf veins if you canNet, or parallel.
- See the root only if it is available to look atTap or fibrous.
- Note they often pair; record only what you sawHonest.
7A habitat is the place the jobs happen
Habitat is the place: pond, bark, soil. Jobs (find food, hide, make food in light) happen there. A habitat you cannot point to is a word only.
A habitat-word with no pointed place is a poster.
Figure. A habitat is where food, water, and shelter jobs actually run — not a pretty backdrop.
How it works
- Point to the placeThis pond.
- Name a job that happens thereIf you saw it.
- Call that place the habitat for those jobsPlace + jobs.
8A miss: grouping only by “cute” or “useful”
Cute and useful are human likes. They are not stem, vein, move, or habitat tests.
A useful cow and a useful neem did not become the same group by usefulness.
Figure. Cute or useful is not a Class 6 grouping test. Shared parts and jobs are.
How it works
- Hear cute or usefulA like.
- Ask for a science testStem, move, place.
- If only the like remains, call the missNot a group-test.
Grouping plants by “pretty” is
- Not this chapter’s grouping test
- The stem test
- A habitat
Name height, stem, veins, or place.
