Definition: Anything that amplifies, or makes something larger or more intense.

Alright class, settle down, let’s take a look! You've got a great start with the dictionary – “amplifies,” meaning to make bigger or stronger. But what does that actually mean? Think of it like this: imagine you have a whisper, so quiet and small, right? It’s hard to hear, isn’t it? An amplifier is like a helper! It takes that little whisper – maybe a sound from a guitar or a microphone - and boosts it. It makes the sound louder, more intense, easier to hear! Like turning up the volume on your radio, you see? So, an amplifier is anything that increases something – whether it's sound, light, or even just a feeling! It takes something small and makes it bigger. Does that make sense? Any questions about our little helper, the amplifier?
