📚 Topic Summary
Sound is all around us! It's a type of energy that travels in waves. When something makes a sound, it vibrates, and these vibrations travel through materials like air, water, and even solids. Some materials let sound travel through them easily, while others block sound. Think about how you can hear someone talking through a door – sound travels through the wood!
