5 & 6
When most people think about Helium, they think about birthday balloons and funny sounding chipmunk voices. Sure, these might be the most popular uses, but Helium also has many other interesting uses. There are many fascinating ways of determining the height of a ceiling without having to physically measure its height with a tall ladder and measuring tape! In this science experiment, use a helium balloon to measure the height of your school hall's ceiling height:
STUFF YOU NEED [MATERIALS]
- HELIUM BALLOON
- TAPE MEASURE
- MAGIC MARKER
HOW TO PROCEED [PROCEDURE]
- Attach a long piece of strong string to a helium balloon. You can obtain a helium filled balloon at a fair or local carnival.
- Go to your school hall and stand next to the wall in the inside.
- While guiding the string, allow the balloon to slowly rise to the ceiling.
- When the top of the balloon just touches the ceiling, follow the string down to the floor and make a mark on the string where it meets the floor.
- Allow the balloon to come back down and measure the piece of string from the mark to the top of the balloon to obtain the ceiling height of the hall!
