Why do you think this plant has flowers that look like
bees?

BEE ORCHID

OBJECTIVE:

• Explore how similar variations in the population due to

inherited mutations can result in an adaptation
over generations

“The Father of Natural Selection”.

Charles Darwin

Born: 1809
Died: 1882

Multiple Choice

What genetic change allows organisms to survive natural selection in their environments? 

• learned behavior

• acquired traits

• analogies

• adaptations

Multiple Choice

Survival of the Fittest and Evolution were proposed by what scientist?

• Steven Hawking

• Albert Einstein

• Charles Darwin

• Isaac Newton

Multiple Choice

Predict which moth would increase in population

• light 

• dark

Polar Bear

• Small ears to reduce heat loss
• Thick white fur to help keep the

bear warm and for camouflage in
the snow

• Thick layer of fat to help insulate

for warmth

• Large paws to stop the bear from

sinking in the snow

• Sharp teeth to eat prey easily.

Camel

• Large feet to reduce the pressure

the camel exerts on the sand

• Hump(s) containing fat, which the

camel can use for energy (the fat
doesn’t insulate its body)

• Nostrils are lined with hair and can

shut to stop sand getting into the
nose

• Thick lips, so the camel can eat

prickly desert plants

• Bushy eyelashes to stop sand from

getting in their eyes

Giraffe

• Horns to fight with other giraffes
• Patterned coat for camouflage
• Leathery mouth to eat tough and

prickly plants

• Long neck and legs to help the

animal reach food high up in the
trees

• Long, tough tongue that can grip

leaves and branches

Cactus

• Thick stem full of spongy tissue that

can absorb lots of water

• Spines are curled leaves that decrease

surface area and reduce water loss
through transpiration and deter
animals from eating the plant

• Thick, waxy epidermis to reduce water

loss

• Shallow, but expansive root system to

increase the water uptake

• Stem contains a high density of

chloroplasts for photosynthesis

Barn Owl

• Flexible neck allows the owl to see in

all directions

• Soft feathers for near-silent flight to

catch prey without being heard

• Large wingspan compared to body

mass, meaning they can fly very slowly

• Asymmetric ears allows the owl to

pinpoint the direction of sound with
high accuracy

• Sharp talons to grip prey

Multiple Choice

What is an adaptation?

• a special feature that helps animals survive

• the animal's environment

• the way an animal hunts

• predators eat prey

Multiple Choice

Armor is an adaptation that helps animals...

• hunt

• protect themselves from predators

• run quickly

• blend in with their surroundings

Multiple Choice

Sharp teeth are an adaptation. How do sharp teeth help animals survive?

• Animals can use them to attack their prey.

• Animals can run away from danger.

• Animals can avoid the cold weather.

• Animals can fly away.

Multiple Choice

Camouflage and mimicry are examples of ___________ adaptations.

• behavioral

• special

• physical

• predatory

Multiple Choice

___________ is a term used to describe animals that blend into their habitats.

• Mimicry

• Camouflage

• Adaptations

• Instincts

Multiple Choice

A cub will learn how to hunt by watching and copying its mother, which is a/an ___________ behavior.

• instinctive

• adaptive

• learned

• mimicry

Multiple Choice

What is an adaptation?

• a special feature that helps animals survive

• the animal's environment

• the way an animal hunts

• predators eat prey

Multiple Choice

A green snake blends in so predators can NOT find it. This is an example of?

• Hibernation

• Mimicry

• Migration

• Camouflauge

Multiple Choice

Birds flying south 800 miles to find food and to escape cold winters is an example of

• Hibernating

• Migrating

• Camouflage

EXIT TICKET:

INDEPENDENT CLASSWORK:

MAKE A GOOGLE SLIDE that shows 5 examples of living things and their adaptation
to the environment

Do not include the examples given by the teacher (Polar bear, Camel, Giraffe, Cactus,
Barn owl)

Multiple Choice

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice

• The hawks eat more dark mice than light mice because the dark mice taste better

• The hawks eat more light mice than dark mice because they can see the light mice more easily

• The hawks eat more dark mice than light mice because they can see the dark mice more easily

Multiple Choice

Process by which individuals that are better adapted to their environment are more likely to survive and reproduce than others of the same species

• punctuated equilibrium

• adaptation

• natural selection

• artificial selection

Multiple Choice

Natural Selection is driven by a change in the environment and survival of the

• Smartest

• Fastest

• Most well adapted

• Biggest

Multiple Choice

The trees these moths used to live on were white, but have been covered in soot from coal factories. Which moth will be more successful in this environment?

• Dark moth

• Light moth

• Both will be equally successful

• Neither will be successful

Multiple Choice

Dogs evolved from wolves as an example of....

• Selective Breeding

• Natural Selection

• Mutations

• Extinction

Multiple Choice

What is the advantage of having different shaped beaks?

• To look different from other species.

• To be able to eat the food readily available in the environment.

• To protect itself against predators.

• To protect itself against prey.

Multiple Choice

A change in genetic material

• Mutation

• Natural Selection

• Evolution

• Variation

Multiple Choice

An inherited trait that helps an organism survive and reproduce in its environment

• Mutation

• Adaptation

• Natural Selection

• Evolution

Multiple Choice

The process by which organisms tht inherit advantageous traits tend to reproduce more successfully thatn other organisms do

• Variation

• Articifial Selection

• Natural Selection

• Evolution

Multiple Choice

The practice by which humans select plants or animals for breeding based on desired traits

• Artificial Selection

• Natural Selection

• Variation

• Evolution

Multiple Choice

The process by which populations change over time.

• natural selection

• variation

• artificial selection

• evolution

Multiple Choice

Drawn observed several different types of finches.  Why are there so many different types?

• Finches live in different places, but eat the same food.

• Finches live in the same place, but eat different types of food.

• Finches live in different habitats and eat different types of food.

• Finches are found all over the world.

Multiple Choice

The differences among a species, like different bird beaks, are called

• genes.

• variations.

• traits.

• theories.

Multiple Choice

Organisms with the most beneficial traits will survive.  This is commonly known as

• theory of evolution.

• variations.

• survival of the fittest.

• ecosystems.

Multiple Choice

This scientist developed the theory of evolution as he studied the finches.

• Charles Darwin

• Isaac Newton

• Albert Einstein

• Marie Curie

Multiple Choice

Behavioral changes of individuals of a species that allow for better survival. (Acquired traits)

• Variation

• Adaptation

• Behavior

• Environment

Multiple Choice

Where the better adapted organisms survive to pass traits along to offspring.

• Evolution

• Natural Selection

• Extinction

• Artifical Selection

Multiple Choice

What are the most studied animals in the galapagos?

• Finches

• Tortoises

• Turtles

• Lizards

Multiple Choice

What is the advantage of having different shaped beaks?

• To look different from other species.

• To be able to eat the food readily available in the environment.

• To protect itself against predators.

• To protect itself against prey.

Multiple Choice

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.

• Because they come from dominant alleles.

• Because they come from recessive alleles.

• Because the trait is an acquired phenotype.

Multiple Choice

Do organisms "decide" to evolve and change?

• Yes, they know they need to change to survive 

• No, they change because of natural selection
