Zoology & Botany


Prepare a picture of/book about/a toy lizard in advance, as well as a sample of scales

Say: Look at this animal. (Show a picture of a lizard.) This is a reptile.

Remember, to be classified as a reptile, an animal should have a backbone (It is a vertebrate) lungs and need air to breathe. (Hold the sample of scales; Show it to the baby) say: Its body is covered in scales. Almost all reptiles are cold-blooded and most of them lay eggs. (Point to the lizard) Say: Lizards are a widespread group of squamate reptiles. Most lizards have dry, scaly skin. Lizards have eyelids that clean and protect their eyes when they blink. Lizards don’t have earflaps like mammals do. Instead, they have visible ear openings to catch sound, and their eardrums are just below the surface of their skin. They have four legs, clawed feet, and a long tail. Lizard tails help in balance and movement and fat is stored in the tail.

Go back to the picture of the sheep. Say: let’s find sheep’s body parts. This is its head, eyes, nose, mouth, body, legs: 1,2,3,4; this is its tail. Lizards have a weak tail. A small bump or tug will break it off. Some lizards can grow a new tail. Do you know baby that Lizards hibernate (to pass the winter dormant or inactive) during winter time? Yes, lizards hibernate during the cold periods of the year, making their homes in tree trunks, rocks and wherever they can find shelter. Since lizards are cold-blooded animals with no internal heating capabilities, so they must rely on heat from external sources. When winter comes, they are forced into hibernation. Lizards are living things and need energy to survive. Some lizards eat bugs, snails and spiders. Others eat plants, small animals, or even other lizards. So, Lizards are omnivorous since their diet is based on both plants and other animals. Most lizards use their eyes to look for food. Some use their sense of smell. The lizard shakes its prey in its jaws before chewing it and swallowing it whole. After emerging from hibernation, the males defend breeding territories from other males. Lizards mate in April or May. Most female lizards deposit their eggs in a simple nest. The female may coil around her eggs to protect them from intruders. Other lizards do not lay their eggs, but give birth after hatching their eggs inside the body. Still other lizard species reproduce similar to mammals, giving birth to live young. Unlike female mammals, these female lizards do not nurse or care for their young after birth. When it comes to lizard habitat and distribution it is extremely diverse. Antarctica is the only location in the world where there isn’t some species of Lizard. Lizards need a warmer climate as they are cold blooded. However, when it is cooler they are able to slow down their body functions and to survive. Lizards are found in a range of habitats including meadows, woodland, marshes, swamps, damp forests, moors, sand dunes and rubbish dumps. Common lizards live mainly on the ground, although they may climb onto rocks, logs and low-growing vegetation. We need to take care of Lizards and treat them with respect because they are living things just like us, people.
