### Core Idea Lessons – Introducing Comparison of Properties

 Physical Sciences Understanding Measurement Engineering & Technology Feeling the Difference Comparing Two Objects Comparing to a Standard Placing Objects in Size Order Introducing a Measuring Unit Creating Your Own Unit of Measure Measuring Rectangular Blocks Measuring Objects Measuring with Two Different Units Measuring with a Tape Measure Measuring the Difference Recording Measurement on a Graph Objects and Distance Measuring Distance Representing Distance on a Diagram Replicating a Diagram Introduction to the Foot as a Unit of Measurement Measuring the Classroom Recording Measurement on a Graph Objects and Distance Measuring Distance Representing Distance on a Diagram Replicating a Diagram Introduction to the Foot as a Unit of Measurement Measuring the Classroom

 Scientific and Engineering Practices (Skills) Crosscutting Concepts Asking questions (for science) and defining problems (for engineering) Developing and using models Planning and carrying out investigations Analyzing and interpreting data Using mathematics and computational thinking Constructing explanations (for science) and designing solutions (for engineering) Engaging in argument from evidence Obtaining, evaluating, and communicating information Patterns: organizing, classifying, and sorting objects by properties and dimensions Cause and effect: the interaction of physical elements on living organisms and Earth processes Scale, proportion and quantity: measuring using standard and non-standard units; using scale models Systems and system models: replicating diagrams; understanding life and Earth cycles Energy and matter: defining the properties of matter; sunlight and plant life Structure and function: comparing living and non-living objects; defining structure and function of living things Stability and change: determining if proposed solutions solve a problem
