Final answer:
To improve the clapping experiment for recording echo sound, students can vary the environment, distance, and intensity of the clap to observe their impact on the echo.
Step-by-step explanation:
To improve the experiment of clapping to record echo sound, students could make the following modifications:
- Disrupt the environment by introducing obstacles or changing surfaces to see how it affects the echo.
- Change the distance between the clapping source and the reflecting surface to observe how it influences the echo.
- Vary the intensity or strength of the clap to see if it affects the echo.
By implementing these changes, students can conduct a more comprehensive investigation into the phenomenon of echo.
