Meluhia (class 7) Motion And Time

# Schedule

Jul 28 - Aug 14 (2 weeks)

# Instructional objectives

• Understanding the importance of frame of reference to describe the state of a system.
• Differentiate motion and rest with respect to the frame of reference.
• Understanding distance, displacement, speed, velocity, constant speed, average speed, instantaneous speed,uniform motion, non- uniform motion etc.
• To understand the concept of keeping time and different methods of calculating time with accuracy
• Understanding the need of a graph.
• Analysis of distance time graph.

# Teaching process

• Asking them the importance of knowing time, different methods of measuring time during ancient days, evolution of pendulum clock, different types of clocks etc.
• Explaining motion and rest with respect to different frames of reference. Recording motion of objects in a given span of time, measuring distance, calculating the average speed, instantaneous speed etc.
• Plotting distance-time graph and analyzing the graph. Discussing why plotting graph is superior over other methods of recording data such as observation table,

# Activities

• Watching the documentary regarding the evolution of clocks https://www.youtube.com/watch?v=NENPdT4LASw
• Calculate the time period of simple pendulum and understand its dependency on length and mass.
• Demonstration of water clock and a sundial.
• Conducting a running race and calculating the speed of each student.
