Learning outcomes
Label some adaptations of animals to live in different environments (G)
Recall how having these adaptations help the animal survive in their habitat (F)
I can describe how these adaptation allow them to survive (E)Slide3
Look at the following…
What do these animals have in common?Slide4
Animals in Cold Climates
Common features:
Thick fur coats
Layer of blubber under the skinColour – many change colour in the summerWhat about body shape?Slide5
Body Shape
Have fat, round body shapes with short legs
Have small ears – why?Slide6
Look at the following…
What do these animals have in common?Slide7
Animals in Dry Climates
Common features:
Large thin ears
Little body fatThin, silky furLong limbs to help spread heatThey also often only come out at night. Why?
What about body shape?Slide8
Body ShapeSlide9
Surface Area to Volume Ratio
Animals loose heat from the body surfaces that are in contact with the surrounding air/water.
Reducing this contact surface reduces heat loss
Increasing the surface increases heat lossSlide10Slide11
Surface Area to Volume Ratio
Hidden surfaces are exposedSlide12
Adaptation in animals
On your own:
Using these keywords in your answers:
adaptation, conserve,
surface area : volume ratio, camouflage.
An elephant has a small surface area compared to its volume. How will this affect it in hot climates?Why do very small animals struggle to live in the arctic?
Why are arctic foxes white in the winter?
Wrinkly elephants?
Big eared foxes?
