Unit A -The World of Living Things
Main Idea: The basic unit of all kingdoms of life is the cell. All living things interact with each other and the nonliving environment. Energy flows through ecosystems from the Sun through producers to consumers, and ultimately to decomposers. Plants have structures and functions that enable them to fulfil their role as important producers.
Unit B - Animals as Living Things
Main Idea: Many kinds of animals have different structures that serve different functions in growth, survival, and reproduction. The behavior of individual organisms is influenced by internal and external cues. Animals are adapted to meet their needs in their environments.
Unit C - Earth and Beyond
Main Idea: Earth is in constant change. Earth's materials, such as rocks and soils, have varied properties, which make them useful resources as well as clues to changes on Earth. Fossils provide evidence of life in the past and changes that haave happened over time. Earth is part of a solar system. The sun and planets, and other objects that revolve around it. Other than the Sun, these objects have patterns of movement.
Unit D - Water and Weather
Main Idea: The continuous interchange of water between Earth's surface and the atmosphere provides Earth with its fresh water supply. This interchange is also basic to weather changes on Earth. the formation of clouds and precipitation, as well as changes in air pressure.
Unit E - Matter
Main Idea: Matter has observable properties and can be measured by concepts of mass, volume, and density. Properties are used to group elements together in the periodic table. Tiny particles of matter are in constant motion. Matter can undergo physical and chemical changes.
Unit F - Energy
Main Idea: Energy is needed to do work and can be potential or kinetic. Energy comes in many forms and can be transformed from one to the other. Electrical energy can be static or flow in circuits. Electric current can produce magnetic forces and moving magnets can produce electric current.
