Identifying Uniform and Non-Uniform motion in Motion and Time – Class 7 Science Experiment

Chapter Name: Motion and Time

Activity Name: Identifying Uniform and Non-Uniform motion in Motion and Time

Activity Description:

In this experiment, we will identify examples of uniform and non-uniform motion from a given set of scenarios.

Required Items:

1. Pen/pencil
2. Worksheet with examples provided

Step by Step Procedure:

1. Take out the worksheet with the examples given: Movement of hands of a clock, A boy cycling in a crowded place, Movement of a housefly, The fan in an air cooler running at a fixed speed, A train entering into a railway station, Kite in the air, Rotation of Earth.
2. Read each example carefully and visualize the motion described.

Experiment Observations:

• Movement of hands of a clock – (U) Uniform
• A boy cycling in a crowded place – (NU) Non-Uniform
• Movement of a housefly – (NU) Non-Uniform
• The fan in an air cooler running at a fixed speed – (U) Uniform
• A train entering into a railway station – (NU) Non-Uniform
• Kite in the air – (NU) Non-Uniform
• Rotation of Earth – (U) Uniform

Precautions:

1. Ensure that the examples provided are understood by all participants before marking them as uniform or non-uniform.
2. Pay attention to the wording of each example to avoid misinterpretations.
3. Double-check the marked answers to ensure accuracy.

Lesson Learnt from Experiment:

Through this activity, we learned to differentiate between uniform and non-uniform motion. Uniform motion is when an object covers equal distances in equal intervals of time, while non-uniform motion is when an object covers unequal distances in equal intervals of time.

We also observed that various real-life examples exhibit different types of motion, and it is essential to understand these concepts to study motion and time in greater depth.
