Science and Engineering Practices: 1. Asking Questions and Defining Problems 2. Developing and Using Models 3. Planning and Carrying Out Investigations 4. Analyzing and Interpreting Data 5. Using Mathematics and Computational Thinking 6. Constructing Explanations and Designing Solutions 7. Engaging in Argument from Evidence 8. Obtaining, Evaluating, and Communicating Information ||Next Generation Science Standards||Grade 4||Science and Engineering Practices|||Develop a model to describe that matter is made of particles too small to be seen. [ Examples: adding air to expand a basketball, compressing air in a syringe, dissolving sugar in water, & evaporating salt water.]||Next Generation Science Standards||Grade 5||Physical Science||Matter and its Interactions|||Make observations & measurements to identify materials based on their properties. [Examples of properties: color, hardness, reflectivity, electrical conductivity, thermal conductivity, response to magnetic forces, & solubility; density is not intended as an identifiable property.]||Next Generation Science Standards||Grade 5||Physical Science||Matter and its Interactions|||Science and Engineering Practices: 1.
