Science/7
th

grade

Station 1


Environment:


cold, snow, frozen ground, Tundra



Adaptations
:


white fur for camouflage, thick coat of fur
, sm. ears


seal and polar bear have layer of blubber


Station 2


Organisms that could live here
:

rattle snake, camel, lizards,
desert
mouse, owl,
cactus



Adaptations for survival:

camouflage, bury in sand, active at night, store
water, waterproof scales



Adaptation
:

characteristics of a species that allows them to
live successfully in their environment


Station 3


*Competing for money, prize,
status of
eating
the most hot dogs.

*Competing for sunlight, space,
nutrients
from the soil.


*Competing for space to
reproduce

lay eggs

Station 3


Competition
:

the struggle between
organisms for limited
resources.



Station 4

Common theme in all photos is one organism is being eaten by
another organism.



Predation:

the interaction when one organism kills and eats another
organism.



Prey
: seal, mouse, zebra,
bee
(
Prey
: organism being hunted)



Predator
: shark, snake, lion, preying
mantis



(
Predator
: Organism doing the hunting)

Camouflage



Bright colors for warning



poisonous


3.




4.









False eye, streamlined body, safety in numbers,

fins to swim







camouflage, stand up to


appear bigger

3. 4.









Sharp claws & teeth
, sharp beak, claws, hard shell


Excellent hearing

hooked beak, talons,



sharp teeth, strong
tail

camouflage

Station 7

1.
The rabbit is the prey and the fox is the
predator. Evidence from graph
-

every time
fox population increases, the rabbit
population decreases indicating they are
being eaten by the foxes.

Station 7

2. If
the graph extended another 10 years (into
year 50
),

The
rabbit population would increase
peaking around year 46. The fox population
would decrease, reaching its lowest point
around year 44. This conclusion is based on the
repeating pattern that is shown between the
prey and predator shown in the graph from
years 0 and 40.


Station 7

3. If
the foxes became overpopulated,
the rabbit
population

would
decrease
(possible die out) since they are food for
the fox.

Station 8

1.
This organism can puff up its spiny body and

squirt
blood from its eyes.


Prey adaptation


the horned lizard (toad)


2. This organism has many rows of sharp teeth

and pores
on the sides of its head
for sensing

electromagnetic
fields.


Predator
adaptation
-

shark


Station 8

3. This organism’s body is hidden below the water,


but its eyes and nostrils protrude above the water.


Predator adaptation


crocodile or hippo



4. This organism travels in herds and when grouped


together, they easily confuse other animals with


their stripes.


Prey adaptation
-

zebras


Station 8

5. This organism secretes a musky odor and is a
relative of the black and white animal you know.



ferret or badger


6. This organism can easily change its color to
blend in with its environment.



chameleon


7. This organism uses echolocation.



dolphin/porpoise, bat
