Description: Thinking Slides: docs.google.com/presentation/d/1JN8TIcwQDP1NET4HpLvkdYjRXttnFqI7LwT4hK5cfBU/template/preview The Wonder of Science: thewonderofscience.com/mlccc35 In this video Paul Andersen shows conceptual thinking in a mini-lesson on proportional relationships. Two examples are included in the video and two additional examples are included in the linked thinking slides. TERMS Quantities - the amount (or number) of a thing Proportional relationship - relation of one dataset to another dataset Directly - two quantities are proportional to each other (linear proportion) Inversely - as one quantity increases the other decreases. Product of values is constant. Magnitude - the size, scale or importance of properties and processes This progression is based on the Crosscutting Concept elements from the NRC document A Framework for K-12 Science Education. “Proportional relationships (e.g. speed as the ratio of distance traveled to time taken) among different types of quantities provide information about the magnitude of properties and processes.” Source: nextgenscience.org
