Segment A of Science 3 teaches students that organisms and their environments are interconnected, and that changes in one part of the system will affect other parts of the system. They also learn that plants have distinct stages in their life cycle, share common characteristics and make their own food using air, water, materials in the soil, and light energy from the sun. Some plants have special adaptations that allow them to live in specific areas. Animals, too, have distinct stages in their life cycle, share common characteristics and need light, water, and nutrients to live. Finally, they study the water cycle and learn that water exists in three states – solid, liquid, and gas, that water recycles through a water cycle, and that watersheds, rivers, wetlands, and oceans of the world are an interconnected system.

In Segment B of Science 3, students will discover that matter has observable and measurable physical properties, and that a force must act on matter to move it—either speed it up or slow it down. Energy exists in many forms and can be changed from one form to another (transformed) as it moves through a system. A force is required to change an object’s speed or direction. Finally, students will learn that the earth system changes constantly as air, water, soil, and rock interact, and the earth is a part of a larger sun, earth, moon system.
