PowerPoint for an educational technology class I'm taking, based off a lesson plan I made.

All mammals have two things in common:
All mammal mothers have mammary glands that make milk for their babies to drink.
All mammals have hair, even if they only have a little bit.
Mammals also share these traits with other animals:
Mammals carry their babies inside while the baby grows.
After the baby has developed, the mother gives “live birth,” which means the baby moves and has a heartbeat when it’s born.
Mammals are all vertebrates, which means they all have a backbone, or vertebrae.
Mammals can control their own body temperature.
If they’re too hot, they sweat
If they’re too cold, they shiver to keep warm
This is called being warm-blooded.
Monotremes are mammals that lay eggs.
Marsupials give birth to immature babies.
The babies are kept in the mother’s pouch until they’re big enough to survive by themselves.
Placental mammals are mammals that get everything they need while growing from a placenta, an organ the mother has.
The placenta gives the growing babies food and oxygen.
The only flying mammal is the bat.
Dogs, tigers, raccoons, and otters are all carnivores.
Carnivore mammals are at the top of the food chain and eat meat.
They have sharp teeth and are usually very fast.
Mice, rats, squirrels, and chipmunks are all rodents.
Rodents have oversized front teeth and chew on anything they can get their paws on!
Hedgehogs, moles, and shrews are all this type of mammal.
Insect-eaters are very similar to rodents – can you figure out how they’re different?
That’s right! It’s because insect-eaters eat only insects, and rodents eat mostly grain.
Cows, giraffes, hippos, horses, pigs, deer, camels, and sheep are all hoofed mammals.
Hoofed mammals have toes that are hard and stuck together, called hooves.
Hoofed mammals either have an odd number or even number of toes.
Which kind is this hoofed mammal shown, odd or even?
The only trunked mammal is the elephant.
The elephant’s trunk is a stretched out nose and mouth.
Have you ever fed an elephant a peanut at the circus or zoo? They use their long trunk to grab the peanut from your hand!
Dolphins and whales are marine mammals.
Marine mammals live in the water, but they have lungs and breathe air like you and me. That’s why sometimes you see them go to the surface of the water – so they can breathe!
Dolphins and whales do have hair all over their bodies, but it’s not very thick and hard to see, even if you get close to them at the zoo.
Can you think of any famous marine mammals from movies or stories?
Sloths, armadillos, and anteaters are toothless mammals.
Toothless mammals have no front teeth.
Can you think of some ways toothless mammals can eat without having front teeth?
Primates have opposable thumbs and flexible fingers.
Look at your hand. See your thumb and fingers, how you can hold the mouse you’re using for this project?
That’s using your opposable thumb and flexible fingers!
YOU are a primate. Can you think of other mammals that are primates like you?
Mammals do have mammary glands, but they also have one other thing in common with each other.
Some mammals do give live birth, but there are other things they all have in common.
Mammals do all have hair, but they also have one other thing in common with each other.
All mammals have mammary glands AND hair all over their bodies.
A mouse is a rodent, which is a placental mammal.
What is a mouse?
A koala is a marsupial. Mother koalas have a pouch that they keep their babies in until the babies can take care of themselves.
Monotremes are animals like the duck-billed platypus. They lay eggs.
Koalas have pouches they keep their babies in until the babies can take care of themselves. What type of mammal does this?
Insect-eaters are pretty small and they only eat insects. Horses eat things like hay and apples.
Horses have two toes fused together to make a hoof.
Horses eat hay and fruit. They can travel far distances without their feet getting tired.
When you go for a ride on a horse, you put a bit between its teeth so you can make it go where you want.
You may eat meat, but there’s a type of mammal you fit better!
Humans have opposable thumbs and flexible fingers, just like monkeys and chimpanzees.
You may enjoy a steak every once and awhile, and you might like swinging from trees, but you fit one of the choices better!
Mammals all have:
What are the three different types of mammals?
What are the different types of placental mammals?
Flying Primates Carnivores
Rodents Marine Trunked
Insect-eaters Hoofed Toothless
See you next time!!
