| Kinematics and Dynamics: Overview, Skills Required, & EALRs |
||||||||||||||||||||||||||||||||||
Overview: Students will translate their experience with simple kinematics (linear motion & free fall) into a computer model.Students will change variables and analyze how these changes affect an object’s motion. In dynamics students perform experiments to discover Newton’s first and second laws of motion. Using previously constructed models students examine graphs to determine relationships between force, mass, and acceleration. Prior Knowledge/Skills Required: Prior to engaging in the modeling activities, students should have performed one or more simple linear motion activities.This is an introduction to STELLA, so they do not require any prior knowledge of this software.They should have been introduced to the basic motion equations (velocity and acceleration).In addition, they should be aware of the graphs that result from constant velocity and constant acceleration of motion. Students should also understand the physical relevance of the slope and y-intercept and what it means if the slope is negative on a distance-time or velocity-time graph. Applicable State of Washington Essential Academic Learning Requirements (EALRS) for Science: 1.Describe the positions, relative speeds, and changes in speed of objects. 2.Know the factors that determine the strength of various forces. 3.Identify questions that can be answered through scientific investigations. 4.Design, conduct, and evaluate scientific investigations, using appropriate equipment, mathematics, and safety procedures. 5.Use evidence from scientific investigations to think critically and logically to develop descriptions, explanations, and predictions 6.Correlate models of the behavior of objects, events, or processes to the behavior of the actual things under investigation; test models by predicting and observing actual behaviors or processes. |
