Fire sprinklers are a lifesaving technology, but have you ever considered how they work? This video shows a hands-on investigation that simulates how the liquid inside a fire sprinkler bulb may be affected by thermal energy from a fire.

Watch this video so you can make observations about how liquids are affected by increasing thermal energy, so you can better understand what role do liquids play in fire sprinkler activation?

With proper adult supervision, you can complete this Hands-on Investigation: How Do Fire Sprinklers Work? 

Check out the Hands-on Investigation: How Do Fire Sprinklers Work? or consider using this graphic organizer to plan and carry out your own investigation.

This video was created in partnership with the National Fire Sprinkler Association and the Fire Safety Research Institute.
