![]() As students work through this data presentation and the questions that follow, every data presentation and exercise presented requires them to use a model to support explanations or solve problems.Ĭonstructing Explanations and Designing Solutions: Construct and revise an explanation based on valid and reliable evidence obtained from a variety of sources (including students' own investigations, models, theories, simulations, peer review) and the assumption that theories and laws that describe the natural world operate today as they did in the past and will continue to do so in the future.Īs students build their own understanding of the types of motion that can be depicted using the velocity vs. time graphs are one model for describing an object’s motion. time graph.ĭeveloping and Using Models: Develop and/or use a model to generate data to support explanations, analyze systems, or solve problems. Careful analysis by students in this passage can afford them the skills needed to describe any motion represented on a velocity vs. time graphs forces students to make claims about the types of motions represented by positive and negative velocities as well as changing velocities. Having to analyze ten trials found within four velocity vs. Analyzing and Interpreting Data: Analyze data using tools, technologies, and/or models (e.g., computational, mathematical) in order to make valid and reliable scientific claims or determine an optimal design solution.
