Third Grade Talking Points

• "Lizards and salamanders are both types of reptiles and amphibians, respectively."
• "Reptiles have scaly skin and are cold-blooded, while amphibians have smooth skin and are cold-blooded as well."
• "Lizards have dry, scaly skin that helps them retain moisture and protect themselves from predators, while salamanders have smooth, moist skin that allows them to breathe through it."
• "Lizards are found in various habitats, such as deserts, forests, and grasslands, while salamanders are mostly found in damp or aquatic environments."
• "Lizards are carnivorous and eat insects, small mammals, and other reptiles, while salamanders are mostly carnivorous as well, feeding on insects, small fish, and worms."
• "Lizards move by crawling or running on their legs, while salamanders have a unique way of moving called 'undulating' where they wiggle their bodies from side to side."
