Science 7 Motion and Stability: Forces and Interactions Assessment Project Description November, 2015 This summative assessment will be your opportunity to demonstrate your understanding of the forces and motion unit. It will take place over the course of 3 classes. The first class will allow you to brainstorm ideas, decide if you will work alone or in a group, and plan your investigation. The next 2 classes will be when you design and engineer a device/object/system that moves in ways that can be manipulated. During these 2 classes you will also investigate how your device/object/system performs. You are to choose the final form of the project in consultation with your teacher. The 2 working days occur during the 16-20 Nov. week. All products are due by 8:00 am on 23 November. All investigations and products must meet the following: ● ● ● ● ● ● ● the investigation must demonstrate changes in position (velocity) and changes in velocity (acceleration) and frames of reference must be specified the investigative portion of the assessment from brainstorming up to the product can be done with a partner or individually the final product must be individual the investigation can be based on previous class activities, but it cannot be identical; the investigation can be a completely new idea safety first, both for you and the environment materials must be available and requested in a timely fashion teacher approval of your plan is required Criteria for success: ● ● ● ● ● ● Average velocity (speed and direction) is accurately determined for motion in the device or system for a clearly defined period. The major forces and their resulting accelerations are described qualitatively. The process of the investigation is made clear and the process follows good scientific and engineering practices. The interpretation of the results of the investigation is made clear particularly with the application of Newton’s Laws of Motion and other appropriate principles (like the Conservation of Momentum). Clear understanding articulated that a force is not required to keep something moving with a constant velocity (inertia). Clear understanding articulated that force causes acceleration (a change in velocity).
