High School Block:
Physics 121/2
This course is a continuation of Physics 112, designed to support learners who plan on taking university or college programs in the fields of science, kinesiology, computer science, engineering, and technology. Learners can expect to participate in a variety of engaging instructional practices and group activities such as demonstrations and investigations. Learners will develop scientific literacy skills including critical thinking, problem solving, and collaboration. Algebra, systems thinking, and technology will be used as tools to spark curiosity and enhance understanding of the physical universe. Topics covered during this course will include how things move (2-dimensional kinematics) and, why things move (2-dimensional dynamics). Learners will have the opportunity to further explore a personal interest and construct a model/prototype in an area of physics.
It is strongly recommended that learners have demonstrated proficiency in skills obtained in Physics 112 and Foundations of Mathematics 110 prior to enrolling in Physics 122.
In all levels of Physics 121/2, the expectation is that educators will adjust course material in breadth, depth, and scope of inquiry dependent on the level of curriculum delivery. The goal for learners is to demonstrate critical thinking and enact skills relevant and necessary to the learning area. The level 1 course is not different in the number of skill descriptors; rather, there are increased expectations in the level 1 course in terms of depth of understanding, and learner self-efficacy. Educators should provide more opportunities in the level 1 course to participate in higher-order thinking activities.
