Bell-ringer: 5 minutes p.s. DO NOT MOVE DESKS TODAY! State the name of the biome we are a part of and how we as humans are capable of surviving in it. p.s. DO NOT MOVE DESKS TODAY!

Frayer Model: Adaptation Fold paper hotdog style, crease, then unfold Fold paper hamburger style, crease, then unfold

Station Work Bring at least 2 pieces of paper Make the following chart: The animal and its adaptations (at least 3-5) The benefit of the adaptation Challenge Number down to 6

Adaptation A change to the body or behavior that has some benefit to the living thing and therefore has been successfully passed down and “perfected” with time to help the organism live and cope in its unique environment

Adapting to Heat Give off heat: larger extremities, tall, skinny, less fur, smaller Handle more heat to save energy and water (Adaptive hyperthermia), let heat go at night Make less heat: cheetahs STOP running, sneak, can cool the brain and let other body parts heat Avoid the heat: Stay in shade or underground during the day Lower metabolism

To Save Water Avoid heat in the day Can go longer without water Concentrated urine, Thicker blood, can re-injest urine or feces of offspring (desperate times!) Get water from food like seeds and succulent plants

Adapting to Cold Bear it: larger size, smaller extremities like ears and legs, more insulation and fat, winter fur, changing body temperature to warm the center of the body Hibernate: lower body temperature, lower metabolism, lower activity Leave: food storage and starvation over long time

Adapting to Water pressure and long dives without air No bones in flukes Collapsible ribs and lungs at low depths Compressed vertebrae Extra capillaries in lungs, 3 times the oxygen gets used from inhaling air 2 times the number of red blood cells Half the heart rate in deep dives Blood gets redirected from the muscles to the brain Higher tolerance of CO2 and lactic acid

Adaptations to aid Movement through habitat WATER: webbed feet, streamlined body, flat tail, nose and ears that close, membrane over the eyes to keep water out, smaller ears, rotated flippers to swim versus walk, fins to stabilize AIR: gliding “patagium” or skin flap, wings, longer and lighter bones ARMS: hyper-extention, smaller thumbs, longer fingers, longer finger nails/claws TAIL: opposable digits in hand, prehensile tail for grabbing and balance GROUND: arms rotated outward to brush dirt from face, closed or no eyes, smaller ears JUMPING: flexible spines, longer legs, tail for balance SPEED: smaller clavicle bone by neck so limbs able to reach all the way to the head for the longest strides, longer limbs, flexible spine, toes in hooves or with more toes off the ground DETECTION IN FOREST: echolocation

Adaptations for Protection from predation/competition Poisons Scents Spines Warning colors Movement of leaves

Abilities to Find Light (Plants)

Summary/HOT group discussion: Which challenge might lead to the greatest variety of adaptations? Why? Imagine you live in the depth of the ocean where there is hardly any light and intense pressure. Create and describe how you would use your own adaptation to survive as a plant and again as an animal.

Population changes, evolution If everyone were able to have some difference to their DNA to allow them to be just a little different, how do we get from that to these extremely different animals today that are really good at surviving in their own conditions? What could be the result of things like climate change? Can animals adapt fast enough? Why/ why not?
