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!

7a. Showing how pushing/pulling moves or does not move an object.
Forces and motion-how things moveMotion is the process of an object changing place or position. Position refers to an object's location. The position of an object all depends on how a person is looking at the object and what it us being compared to, which is known as an object's relative position. Read more...iWorksheets :3Study Guides :1Vocabulary :2
Force and motionWhat Makes Things Move? Forces make things move! A force is a push or pull that can make something move. Gravity is a force! Gravity is a force that pulls things down. Speed is how fast or how slow an object moves. Objects can move straight, up, down, to the left, or to the right. Objects can curve and swerve when they move too!
