Which of the following adaptations helps birds fly?
A
they have more fat than most animals so they can fly for long distances.
B
they have hollow bones so they are lighter
C
they have smaller blood vessels so their hearts have to work less in flight
D
they have a larger stomach so they can absorb food faster

Penguins are unusual birds. They
swim under water but do not fly.
Penguins live in some of Earth’s
coldest climates, where they
feed on sea animals. Unlike most
birds which have bones that are
hollow, a penguin has solid
bones. This difference makes it
easier for a penguin to F
dive deep under water
G
detect fish under water
H stay warm under water

Euglena are microscopic
organisms that live in freshwater
ponds. It has chloroplasts,
moves by a flagellum, and has
an eyespot that is sensitive to
light. Euglena would most likely
respond to sunlight by swimming
A
around the roots of a lily pad
B
beneath an underwater log
C
to the bottom of the pond
D
toward the pond surface
hold its breath under water
How do gills of a fish help their survival?
F
gills allow fish to break down water into oxygen and hydrogen
G
gills allow fish to process energy quicker so they can move faster
H
gills allow fish to breathe in air and water
J
gills allow fish to use the oxygen dissolved in the water.

Pick one of those categories and decide on a specific adaptation. Next, use
your imagination to come up with a completely made up organism that has
that adaptation. Your organism can be a plant, and animal or even a
combination of plant and animal.
find (or make) food, water or nutrients
reproduce (bright colors, noise, dance or display etc)
protection (teeth, claws, shells, thorns, needles etc)
camouflage/hide
move (swim, fly, walk run, jump etc)
Next, draw a picture of your imaginary creature. Try to take up most of the
page so it is easy to see. Save a little room to write a short description of
your organism’s adaptation and how it helps the organism survive.
