Reptiles
Natural Science
Living-
Reptiles don’t live in cold environments.
Reptiles can be found just about anywhere- near lakes, grass, rocks, and even in the desert.
Lay eggs- young receives nutrition from the yolk.
Some reptiles like crocodiles are aquatic- live in water.
Snakes shed their skin- becomes a dull colour, during this process the snake loses appetite and becomes irritable.
Reptiles are drawn to both land and water environment- depends on the food levels at the time.
Survival-
Turtles have a shell for armour.
Crocodiles have lots of sharp teeth.
Snakes have fangs which can be poisonous.
Many reptiles are agile and can run away fast – hide in holes and rocks.
Some snakes bury themselves in the sand
Natural Science
Types of reptiles-
Lizards, turtles, snakes, dinosaurs, Komodo dragon, crocodile, sea snake, river snake, chameleon, iguana, skink, Gila monster.
Natural Science
Anatomy of a reptile-
Body is divided into head, neck, trunk and tail.
Some have 3 chamber hearts, while an alligator has 4.
The scales on reptiles are dry and made from Keratin- strong like our fingernails.
Able to regulate body temperature.
Reptiles use lungs to breathe. Respiratory system – nostrils are separated from the mouth.
Scales protect the reptile.
Characteristics-
Cold blooded, scaly body, lays eggs, vertebrates (have a backbone)
Learners can have a reptile show- a person with knowledge can relate information and learners can see and touch the retiles bought in.
Social Science
Adaptation-
Some reptiles play dead to predators for survival.
A chameleon can rotate his eyes 360 degrees.
Worm Lizard has a pair of tiny dots in the skin that are eyes.
Turtles and crocodiles have simple tongues, snakes have modified forked at the end used to taste and smell.
Green turtles are highly adapted for swimming.
Change-
A chameleon can change his colour to camouflage with the environment -able to change skin from light to dark.
The Pterosaurs was the most advanced aerial reptile, and today there is no other reptile capable of aerial locomotion.
Many tree dwelling lizards and snakes, have had body weight reduced, allowing them to fall from high without injury.
In snakes and a few lizard’s the epidermal layer often sheds, in one piece, and accommodating weight gain/loss. The new skin is dull colour.
Relationships and interdependence-
A community is formed within a burrow- a tortoise protects a burrow from a snake using it’s shell, the other animals eat the dung and insects.
The teacher can bring a reptile in and let the learners talk about what they see and eventually draw.
Tecnology
Structure of a reptile-
Depend on the heat of the environment – to regulate body temperature (Ectotherms).
Vertebrate animals.
3 Chamber hearts (most reptiles)
4 Chamber hearts (Crocodile).
Technology required-
Reptiles are cold blooded, if kept as domestic pets will require Fluorescent bulbs/Ultraviolet light.
Cage- to keep enclosed.
Logs.
Heating pads.
Hiding spaces -which can be made (boxes, caves)
