Objectives (5 - 7 minutes)
-
Understanding Simple Harmonic Motion (SHM): The teacher will ensure that students have an understanding of the concept of SHM, its characteristics, and the importance of studying SHM in physics. This includes understanding that SHM is a periodic, oscillatory motion.
-
Identifying the Parameters of SHM: The teacher will guide students in identifying the parameters of SHM in a problem, such as the amplitude, period, frequency, and phase. This will allow students to effectively solve the equation of motion.
-
Solving Motion Problems with Equation of Motion: The primary objective of the lesson is for students to be able to solve problems involving the equation of motion for SHM. They should be able to calculate the position, velocity, and acceleration of an object in SHM at any point in its motion.
- Secondary Objective: Additionally, the teacher will encourage students to apply their understanding to real-world scenarios or contexts from other disciplines.
The teacher should establish these Objectives at the beginning of the lesson, so students know what to expect and can mentally prepare for the lesson. This will also help keep the lesson focused and on-pace.
Introduction (10 - 15 minutes)
-
Review of Prior Concepts: The teacher will begin the lesson by reviewing important concepts that are necessary for understanding the topic at hand. This may include a quick review of circular motion, periodic motion, and oscillation. This review can be done through a brief classroom discussion, group questions, or a short quiz.
-
Real-World Problem: The teacher will then present students with two real-world scenarios that involve Simple Harmonic Motion (SHM). The first scenario can be the swinging of a pendulum, and the second can be the motion of an object attached to a spring. The teacher should ask students to think about what they already know about these scenarios and how they might apply that knowledge to understanding SHM.
- Example 1: Imagine a pendulum swinging back and forth. How would you describe its motion?
- Example 2: If you push on an object attached to a spring and then release it, what will happen to the object?
-
Contextualization: The teacher will then explain to students the importance of SHM in everyday life and other areas of science. SHM is a common phenomenon that occurs in many physical systems, such as clocks, sound waves, and light. Additionally, SHM is fundamental to understanding many other topics in physics, such as quantum theory and the theory of relativity.
-
Introduction to the Topic: To capture students' attention, the teacher can share some interesting facts or applications of SHM. For example:
- Fun Fact 1: Did you know that Simple Harmonic Motion is one of the most common equations in physics? It is used to describe the motion of everything from molecules to galaxies!
- Fun Fact 2: SHM is the basis for many inventions and technologies that we use in our everyday lives. For example, clocks, altimeters, and seismographs (used to measure earthquakes) all work based on SHM.
-
Presentation of the Topic: Finally, the teacher will introduce the topic of the lesson: the equation of Simple Harmonic Motion. The teacher will explain that the SHM equation is a powerful tool that allows us to predict the position, velocity, and acceleration of an object in SHM at any point in its motion.
