Dinosaurs may be extinct, but reptiles are distant cousins to the beasts that once walked the earth. From snakes and lizards to iguanas and tuataras, children learn what factors make them different from other animals. In this videotape, students explore the mysterious, often misunderstood, world of reptiles and learn about their characteristics and how they differ from amphibians. This videotape correlates to the following National Science Education Standards for Life Science: characteristics of organisms; life cycles of organisms; and organisms and environments. The videotape is accompanied by a teacher's guide and a hands-on student experiment. (CCM)
