B2.1 What stays the same and what changes
Example
For a kitten growing into a cat, list what stays the same and what changes.
- Stays the same: four legs, fur, whiskers, the number of eyes and ears.
- Changes: it gets heavier and taller; its first small teeth are replaced by bigger ones; it stops needing its mother's milk.
Remember: Littermates grow at slightly different rates — still the same kind of animal.
B2.2 How animals move
Example
Describe how a snail, a frog, a fish and a kangaroo move.
- Snail: glides on one long muscular foot under its body.
- Frog: hops on land, swims in the pond, climbs a wet bank. Fish: fins push against the water.
- Kangaroo: stands and hops on its two back legs; its front limbs are arms.
B2.3 Life cycles
Example
Describe the life cycle of a butterfly.
- Butterfly: egg on a leaf → caterpillar that eats and grows → chrysalis, a hard case made from its own skin → butterfly. A moth spins a silk cocoon; a butterfly does not.
Example
Describe the life cycle of a frog.
- Frog: eggs in a jelly clump → tadpole with a tail → froglet with back legs and a shrinking tail → frog that can leave the water.
Example
Describe the life cycle of a robin and a cat.
- Robin: egg → chick with no feathers → young bird learning to fly → adult.
- Cat: kitten born with eyes shut → drinks milk → grows → adult that has kittens.
B2.4 Comparing changes through a life cycle
Example
Compare how a tadpole and a puppy change as they grow up.
- Tadpole: changes shape completely — loses its tail, grows legs, leaves the water. Metamorphosis: the same animal, changed in shape.
- Puppy: keeps its shape and gets bigger; its eyes open, it walks, it eats solid food.
- Both go from needing care to finding their own food.
B2.5 Adaptations for survival
Example
Explain how a camel survives where it lives.
- Camel: humps store fat for when there is no food; long eyelashes keep sand out; wide feet do not sink into soft sand.
Example
Explain how a polar bear survives where it lives.
- Polar bear: thick fur traps a layer of warm air next to the skin; fat under the skin; wide paws spread its weight on the snow.
Example
Explain how a groundhog survives where it lives.
- Groundhog: sleeps all winter and its body slows almost to a stop. A bear sleeps too, but its body does not slow nearly as far, and it wakes on mild days.
Summary
- Some features stay; size, teeth and food change.
- Foot, fins, legs, wings: each moves in its own way.
- Egg, young, adult — and some change shape completely.
- Adaptations are features and habits that fit the place.
