1. Life Science
– From Molecules to Organisms: Structures and Processes
Objective- Support an argument that plants get the materials they need for growth chiefly from air and water.
5-LS1.C: Organization for Matter and Energy Flow in Organisms. Matter is transported into, out of, and within systems
Plants acquire their material for growth chiefly from air and water. (5-LS1-1)
Energy and Matter
Matter is transported into, out of, and within systems. (5-LS1-1)
– Ecosystems: Interactions, Energy, and Dynamics
5-LS2.A: Interdependent Relationships in Ecosystems
Objective- Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment.
The food of almost any kind of animal can be traced back to plants. Organisms are related in food webs in which some animals eat plants for food and other animals eat the animals that eat plants. Some organisms, such as fungi and bacteria, break down dead organisms (both plants or plants parts and animals) and therefore operate as “decomposers.” Decomposition eventually restores (recycles) some materials back to the soil. Organisms can survive only in environments in which their particular needs are met. A healthy ecosystem is one in which multiple species of different types are each able to meet their needs in a relatively stable web of life. Newly introduced species can damage the balance of an ecosystem.
Systems and System Models
A system can be described in terms of its components and their interactions. (5-LS2-1)
LS2.B: Cycles of Matter and Energy Transfer in Ecosystems
Matter cycles between the air and soil and among plants, animals, and microbes as these organisms live and die. Organisms obtain gases, and water, from the environment, and release waste matter (gas, liquid, or solid) back into the environment. (5-LS2-1)
