From this school year, our secondary students from G9-G10 are able to choose from 9 AP courses, containing AP Chemistry, AP Statistics, AP Calculus BC, AP Computer Science, AP English Language and Composition, AP Physics, AP World History Modern, AP Human Geography and AP Chinese Language and Culture. These advanced courses will provide students an opportunity to really be able to be successful and to push forward and to try their hardest. STEM course is also available to G7-G10 students.

**Class Insight**

By studying kinematics, students are supposed to learn to represent motion – both uniform and accelerating – in narrative, graphical, and/or mathematical forms and from different frames of reference.

These representations will help students analyze the specific motion of objects and systems while also dispelling some common misconceptions they may have about motion, laying a solid foundation for their future scientific studies.

To learn kinematics, students worked as groups and did experiments to find acceleration of free fall in three different methods.

In the first experiment, students used meter sticks, ball and stopwatch to determine the acceleration due to gravity, *g*, by dropping a ball from a known height and measuring how long it takes to fall. By using the data collected and applying the equations of motion, a value for g can be determined.

*students work in groups to measure the height, time and record the data*

The second experiment is finding acceleration of free fall using pendulum. They were required to write an experiment report as their summative assessments of this unit.

The third experiment, students learned to use the light gates to measure the acceleration of an object allowed to fall under the force of gravity.

**Sally: **I love this class, studying with a friend in the Physics classroom, as it has great teachers and expands my understanding and knowledge of physics more than ever.

**Minju:** I learned various kinds of forces such as gravitational force, normal force, and friction. It is interesting as they are all forces on an object, but have different names and ways to work on an object.

**Het: **I think that physics is very interesting and a realistic way to explain why objects behave the way they do.

**Zach: **I think Physics class is interesting and it helps me expand my knowledge and possibly open up my love for a new subject.

**Assessment and Exam**

The AP Physics 1 Exam assesses student application of the science practices and understanding of the learning objectives outlined in the course framework. The exam is 3 hours long and includes 50 multiple-choice questions and 5 free-response questions.
