WARM UP # 10/25 1. List the first letter of the 7 levels in order. 2. Which two levels makes up the scientific name? 3. Which level is more diverse – Class or Family? 4. What did we learn about on Friday? (look at the back agenda board if you forgot)

Adaptations

ADAPTATION – anything that helps an organism to survive in its environment. 2 types: 1. STRUCTURAL – a trait; something on their body * caused by mutation in DNA 2. BEHAVIORAL – way they act (something they do) All organisms need to adapt in order to survive

For example, imagine a bird species. One day a bird is born with a beak that is longer than the beak of other birds in the species. The longer beak helps the bird catch more food. Because the bird can catch more food, it is healthier than the other birds, lives longer and breeds more. The bird passes the gene for a longer beak on to its offspring. They also live longer and have more offspring and the gene continues to be inherited generation after generation. Eventually the longer beak can be found in all of the species. This doesn't happen overnight. It takes thousands of years for a mutation to be found in an entire species.

EX of structural adapt. 1. camouflage 2. thick fur / shedding 3. spines/ tusks 4. spray smells 5. body part shape 6. mimicry tons more!

Some examples of adaption

Mimicry Mimicry allows one animal to look, sound, or act like another animal to fool predators into thinking it is poisonous or dangerous.

All birds have similar characteristics. But many water birds have features that are different from those birds live on land. Long legs are good for wading These wings act as flippers Webbed feet for swimming

Some animals are camouflaged to blend in with their surroundings. This keeps them safe as it is more difficult for other animals to see them or catch them for food. This lizards skin is so similar to the rock colour. These zebra could easily be mistaken for bushes from a distance. This lion blends in well with the grassy background.

Aquatic animals have streamlined bodies to move more easliy in the water.

These animals have adapted to live in the hot climate of the desert. Camels store water in their humps. Ostriches have long eyelashes to keep out the sand. Snakes glide across the hot sands and can shed their skin

These animals have adapted to be more suited to cold temperatures. Layers of fat keep the seals body warm, and small ears stop heat loss. Polar bears are kept warm by their body fat. Deer have a warm layer of fur.

A human adaptation

EX of behavioral adapt. 1. Moving in herds 2. Migration 3. hibernation 4. Playing dead 5. Sitting on rocks to keep warm

adaptations VIDEO 1: On a sheet of paper, list all the adaptations mentioned in the short video

VIDEO: List all the changes and adaptations of elephants over time

Human adaptations Sweating to cool off Opposable thumb Language to communicate Skin colors Body shapes and size Layers of fat Clothes / shelter Agriculture Use of oxygen by our cells Malaria/ sickle cell

PLANTS HAVE ADAPTATIONS TOO Can you think of any? VIDEO – ditto to fill in

PLANT ADAPTATIONS EX: Spines Waxy leaves Deep roots Wide leaves Covered seeds Thick bark Drop leaves Tons more!

Even plants have adapted to their habitats. The cactus has fleshy stems that store water. The water provides support for this lily as it has less developed roots to hold it in place. Dandelions seeds are easily dispersed.

How did plants first begin? Where did they live? How did they evolve? READING ON CELL TO SEED

WARM UP #6 10/9 (7 pts) 1. What is the definition of adaptation? 2. What are the two main types? 3. Give 3 examples of each type. 4. Do you think plants have adaptations? If so, can you name any? * HAVE BOOK OUT TO GET YOUR 5 pts
