DE.2. Materials and Their Properties
2.2. Mixtures and Solutions
Enduring Understanding: The properties of a mixture are based on the properties of its components.
2.2.E. In mixtures, individual components move from areas of higher concentration to areas of lower concentration to eliminate concentration differences. Diffusion is the movement of individual components. (Level: Compact)
DE.6. Life Processes
6.2. Matter and Energy Transformations
Enduring Understanding: All organisms transfer matter and convert energy from one form to another. Both matter and energy are necessary to build and maintain structures within the organism.
6.2.C. Most living things use sugar (from food) and oxygen to release the energy needed to carry out life processes (cellular respiration). Other materials from food are used for building and repairing cell parts. (Level: Important)
