Earth in spaceFreeThe Sun, which is a star, is Earth's source of heat and light. The earth travels in circles around the Sun. The Earth’s rotation every 24 hours results in day and night on Earth. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 1 Natural resourcesNatural resources are found on the Earth and are important to living things. Some natural resources come from below the Earth’s surface. Some natural resources are nonrenewable, which means that can not be replaced. Some natural resources are renewable. Three examples of natural resources we have in abundance on Earth are: sunlight, air, and water. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 1 The solar systemThe Sun is a gigantic star that is made up of hot gases called plasma.

One type of energy is energy that is waiting to happen but has not happened yet. This is called potential energy. Another type of energy is called kinetic energy. This type of energy is energy that is happening now. Read more...iWorksheets: 6Study Guides: 1Vocabulary Sets: 4 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 Sets: 2 SoundSound is energy that travels in a wave that is caused by vibrations. Vibrations are movements made rapidly back and forth. Vibrations travel through the air and into your ear. You hear sounds when vibrating air causes your eardrum to vibrate.

Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 1 Grouping of AnimalsAnimals can be classified, or grouped together, by the things they have in common, such as how they act, where they live, or how they look. Scientists separate animals into two main groups related to whether the animal has a backbone in its body or not. Those animals with backbones are part of the vertebrates group. Those animals without a central backbone are invertebrates. Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 1 Grouping of PlantsPlants are often put into groups by the type of parts or structures they have. They can be grouped according to their types of leaves, stems, flowers, roots, and even seeds. Many plants have leaves that look similar while others have totally different kinds of leaves. Plant and tree leaves may be different in size, shape, and color. Read more...iWorksheets: 6Study Guides: 1 Life Cycles of Plants and AnimalsA life cycle describes the stages an animal or plant goes through from birth to death. Some vertebrates change their appearance a lot during their life cycle while others hardly change at all. Most plants begin as a seed. A seed is a tiny plant, an embryo, in a little package. A seed stays inactive and doesn’t start growing until the conditions surrounding it are just right for it to start growing. Read more...iWorksheets: 2Vocabulary Sets: 3 Main Parts of PlantsA plant has many important parts, such as its roots, stem, leaves, and flower.
