Earth yesterday and todayLife on Earth Has Changed. Many kinds of animals that used to live on Earth are no longer living. They are extinct. Reasons for Extinction: Big changes in the climate. Many times animals could not handle these big changes in the weather. Good news: Many animals have adapted to many changes that happen on Earth so that they CAN survive and NOT become extinct! Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 1 Fossils and dinosaursMany animals have lived on Earth and many still live on the Earth.
Some lived on Earth millions of year ago. Many of these animals unfortunately do not live on Earth anymore. Fossils are things that provide evidence (or proof) of things that lived long ago. A fossil is the outline or piece of something that died millions of years ago. Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 1 The sun and earthThe Sun is a large hot ball of gas. It is also a star. The Sun gives Earth light and heat. Living things need the Sun to live! Sun rays shine on the moon at night which makes the moon bright! The Earth is the third planet from the Sun. There are four seasons: winter, spring, summer, and fall. Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 1 AnimalsFreeThere are many different kinds of animals.

A habitat is the place where plants and animals live. Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 2 Mammals and birdsWhat are Birds? Birds are warm-blooded animals that have: wings, feathers, a beak, no teeth, bones. Birds lay eggs. Their young hatch from those eggs. What Are Mammals? Mammals are animals that have hair. Mammals are the only animals with hair. Mammals are also warm-blooded. This means their body temperature stays the same, even if it is very cold or hot outside. Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 1 Reptiles, amphibians and fishReptiles have scales. Reptiles are born on land. Reptiles are cold-blooded which means their bodies change temperatures with the outside temperature around them. Reptiles lay eggs, and their babies hatch from those eggs. All amphibians begin their life in water with gills. As they grow, they develop lungs – which is
what they use to breathe with on land. They grow legs to use on land too. Fish use gills to breathe. A fish stays in the water for its entire life! Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 1 Water HabitatsWe already know that a habitat is the place where plants and animals live. Now, let’s look at WATER habitats...
