Transcript Adaptions of Living Things: Movement Through Fluids

Adaptions of Living Things:
Movement Through Fluids
Background
• Features that allow a living thing to
survive in its environment are called
adaptations.
• Adaptations may be body parts, abilities
and skills, or behaviours.
• Birds, bats, sharks, and dandelion seeds
all have something in common.
•
• The survival of each of these species, as
well as many thousands of others, relies on
its ability to move efficiently through a
fluid, be it air or water.
• The parachute-like tufts of dandelion
fruits and the helicopter –like motion of
the winged fruit of maple trees, for
example, are adaptations that have
allowed these plants to survive.
• The characteristic form that varies with
each air and water creature has come
about through countless generations of
adaptations.
• Streamlined shape, lightweight bones, and
powerful muscles are but a few of these
adaptations.

Activity One
• Birds of flight!! Pictures.
• Discuss the features of the birds.
• These features , some of which allow birds
to fly, are called adaptations.
• An adaptation can be physical or
behavioural; it allows a living thing to
survive in its environment.
• What adaptations (features) allow a bird to
fly?
• How does the bird move in flight?
• Characteristics birds have- wings, feathers,
body shape and???
• Other than birds, what else can move through
air?
• Insects
archery arrows
• Bats
seeds
• Planes
• Hang gliders
• Rockets
• Darts
• Lawn darts
• Pictures of fish, sharks, whale.
• Adaptations for swimming
• What adaptations allow this animal to
swim through water?
• How does this animal move as it swims?
• Streamlined almost bullet like- shape or
the water creature.
• Other objects that travel through water.
• What other living things and objects can
move through water?
• Humans
• Boats
• Surfboards
• Submarines
• Etc?
• Make a collage of different living things
that are well adapted to moving through
water and air.
• Do the creatures that move through air
have feathers?
• Do all creatures that move through water
have a streamlined shape?
• Do any plants/seeds travel by air? If so,
what are their shapes?
• What are some differences between two
species of birds?
• What so you think the reasons are for these
differences?
• What are some differences between two
species of water creatures?
• What do you think the reasons are for these
differences?
• What are the main characteristics of air and
water creatures that enable them to move?
