๐ Topic Summary
Sound is all around us, and it travels in waves! The loudness or softness of a sound is called its volume, or amplitude. Loud sounds have big, strong waves, while soft sounds have smaller, gentler waves. Think of a roaring lion versus a quiet whisper. The lion's roar has a much larger sound wave than the whisper. Understanding sound helps us appreciate music, communicate effectively, and even protect our ears!
