Bunsen burner

A Bunsen burner is a special tool that scientists use to heat and burn things. It looks like a tube that stands up straight and has a little hook at the bottom to hold a metal plate. There is a rubber tube that connects to the bottom of the tube and to a gas source that makes it work.

When you turn on the gas, it flows through the rubber tube and into the Bunsen burner. Then, you use a little knob on the bottom to open it up and let the gas out. As the gas flows out, it mixes with air to create a flame.

This flame is very special because scientists can control how much air comes in and how much gas comes out to make it bigger or smaller. They can also make it hotter or cooler by adjusting the amount of gas and air mixture.

Scientists use Bunsen burners to heat up liquids in beakers or test tubes, to sterilize equipment or even to make little flames for experiments. It's a really important tool for any scientist to have in their lab!
