UNIT PLAN - FORCES AND MOTION: DYNAMICS
Overall Curriculum Expectations:
By the end of this course, students will:
B1. analyse technological devices that apply the principles of the dynamics of motion, and assess the technologies’ social and environmental impact;
B2. investigate, in qualitative and quantitative terms, forces involved in uniform circular motion and motion in a plane, and solve related problems;
B3. demonstrate an understanding of the forces involved in uniform circular motion and motion in a plane.
Approximate number of days in the unit: 23
Teaching Strategies:
Cores strategies: Think - Pair-share, group work, encourage and motivate students, communication with parents, building strong relationships with students, peer tutoring to improve achievement, etc.
Instructional strategies: Hooks (hook them up from the beginning of the class), daily re-looping of previously learned material, generate data from real life experiences to use in class, activities that make topic relevant to students' interest, problem solving instructions, etc.
Technology: PPT Presentations, Gizmos, Computer Simulations, Videos, Clickers.

Rationale
Since this is the first unit of the course, it is important for students to do well and have a good start of the course.
All the curriculum expectations will be covered throughout the unit in this course. Some expectations will be covered in more than one lesson (i.e. B2.2 will be covered throughout the first chapter) and most of them in one lesson.
Chapter 1
Students will review kinematics concepts from SPH3U (a pre-requisite course) and will learn new ones. In this chapter, during the first five days, I will cover expectation B2.2 Students will learn to describe motion using graphs of motion and equations of motion for objects moving in one and two dimensions. Students also will analyze and explain linear motion in horizontal, vertical, and inclined planes using the concepts of velocity and acceleration (the first two days). Freefalling objects and projectiles are also analyzed (Day three and four). On Day four, students will do a Gizmo activity on Projectile Motion, which will be evaluated for K/U and C. Finally, on Day five, students study the motion of objects from different frames of reference. The material of this chapter is an essential foundation for dynamics, which is studied in Chapter 2.
On Day 6, students will investigate (Lab) the projectile motion. They will analyze and identify characteristics of projectile motion, which is a curriculum requirement. They will write a Lab Report, which will be submitted in two weeks’ time. They will be evaluated on K/U. T/I, C and A.
Chapter 2
On Chapter 2, students will expand their understanding of the concepts and principles of dynamics. The Days nine to thirteen, I will cover expectations B 2.1, B2.3, B2.5, B3.1 and B 3.2. Using Newton’s three laws of motion, students will analyze the forces that act on objects in a variety of situations and predict the resulting motion of the objects. Furthermore, they will use analytical tools such as free-body diagrams, vector addition, and taking-force components to solve dynamics problems in horizontal, vertical, and inclined planes.
On Day fourteen, students will investigate (lab) the coefficients of static and kinetic friction on horizontal and inclined planes, (expectation B 2.4). They will write a Lab Report, which will be submitted in two weeks’ time. They will be evaluated on K/U. T/I, C and A.
Chapter 3
Chapter 3 introduces students to circular motion. I will be covering expectations B 1.1, B1.2, B2.6, and B3.3. Students will be encouraged to relate their personal experiences with circular motion and their knowledge of the principles of dynamics to explain the behaviour of objects moving with uniform circular motion (days sixteen). The next day, students will consider the forces that act on those objects. These two days, also, will be computer simulations on centripetal acceleration and centripetal force, which will be evaluated. Then, on Day eighteen, Universal gravitation, introduced in grade 11 physics, is examined and extended to include the study of satellite motion. This topic is investigated further in Chapter 6.
On Day twenty, students will investigate (lab) the Uniform Circular Motion (expectation B 2.7). They will predict and determine the relationship between the frequency of revolution and the magnitude of the tension force, the radius of the circle, and the mass of the object in motion. They will write a Lab Report, which will be submitted in two weeks’ time. They will be evaluated on K/U. T/I, C and A.
Reviews, Quizzes and Tests
I decided to do two tests for this Unit. The Unit is too large for only one test. There will be one Test on Day 8 on Chapter 1 and another Test on Day 22 or 23 for chapters 2 and 3.
There will be reviews the days preceding the tests, focusing on the material that will be assessed on the tests. During these reviews I will have activities using pair and group work, as well as clickers to ensure that all students have a good understanding of the concepts, before moving to the next one.
I, also, will do two short reviews and Quizzes on Day 15 and 19, to assess and evaluate the concepts on chapters 2 and 3 respectively.
During quizzes and tests students will be assessed on basic concepts covered in specific expectations and evaluated on K/U, T, C and A.
I decided not to do any assignment for this Unit, because students will be very busy with labs, quizzes and tests, almost every week.
Accessibility
If there are students with special needs they will be accommodated or modified accordingly to their IEP. If there are students who struggle, I will give them extra help and will use peer tutoring to help them succeed.
All my lessons, PPT Presentations, worksheets, sample Quizzes, Tests and other materials will be available for students (and parent)s on my Course Website.
