UbD : Forces and Motion – Measuring Motion and Newton’s Laws The process of scientific inquiry to enhance a scientist’s ability to investigate questions and solve problems Stage 1 – Desired Results Essential Understanding: Unbalanced forces cause changes in motion that can be predicted and described. Established Goals: • Given opportunities students will be able to experience, observe and describe in words and pictures motion, including factors of pushing and pulling that create and affect motion. • Given opportunities students will be able to experience, observe and describe in words and pictures motion, Newton’s three laws of motion. • Make qualitative descriptions of the relationship between forces and motion will provide the foundation for quantitative applications of Newton’s laws. State Standards: 12 D: Students who meet this standard know and apply concepts that describe force and motion and the principles that explain them. Understandings: Essential Questions: Students will understand . . . • How to represent and describe motion in a variety of ways. • The strength of the gravitational force between objects is proportional to the mass of the objects the difference between balanced and unbalanced forces. • the application of Newton’s laws in various situations. Essential Vocabulary: • motion • speed • velocity • acceleration • force (Newton) • net force • friction • gravity • free fall • projectile motion • inertia • momentum 1. What are the relationships between forces and motion? 2. What are the variables that affect motion and force? 3. How does Newton’s three laws describe the motion of a moving object? 4. How does gravity impact objects? Resultant Knowledge: Students will know… • the relationship between speed and velocity • the impact of gravity and friction on motion. • each of the three Newton Laws • the impact of the law of conservation of momentum on the movement of objects. Resultant Skills: Students will be able to . . . 1. 2. 3. 4. 5. measure and calculate their speed and acceleration in a variety of situations assess the impact of force, gravity and friction on objects site examples of net force and balance forces. design and conduct investigations involving the motion of objects justify which of Newton’s Laws is evidenced in a variety of examples. Stage 2 – Assessment Evidence Performance tasks. ¾ Compute speed and acceleration of moving objects ¾ Create graphs of moving objects speed and acceleration. ¾ Identify the presence of forces in real life scenarios: speed, acceleration, friction, air resistance and gravity. ¾ Demonstrate the involvement of Newton’s Laws in everyday situations. Other Evidence. ¾ Multiple Choice assessment on key formulas and terms ¾ Completion of math computations ¾ Presentation of Newton Law Project with evidence cartoon images demonstrating each of the laws.
