All About Energy
Energy is the ability to do work. There are two types of energy. 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: 5Study Guides: 1Vocabulary Sets: 5

Changes on earth
A glacier is a slow moving large body of ice. A volcano is an opening in the Earth’s crust from which hot, melted rock forcefully comes out when pressure is built up inside the Earth. An earthquake is a sudden shift in the Earth’s crust that causes the ground to shake and vibrate violently. Weathering is the process of rocks being changed over time by conditions such as rain, snow, ice, pressure.Read more...iWorksheets: 4Study Guides: 1Vocabulary Sets: 2

Grouping of Animals
Animals 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: 4Study Guides: 1Vocabulary Sets: 1
Grouping of Plants
Plants 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.

All plants need water, air, and warm temperatures to grow. Read more...iWorksheets :4Study Guides :1Vocabulary :2
Plant Structure and function
Plants are living organisms made up of cells. Plants need sunlight and water to live and grow healthy. A plant has different parts that are all important in keeping the plant alive and healthy: Roots, Stem, Leaves. A plant’s roots collect water and minerals from soil for the rest of the plant. The main job of a plant’s stem is to carry water and minerals from the roots to the rest of the plant. Read more...iWorksheets :3Study Guides :1Vocabulary :4
