YOU WILL NEED:
- An empty plastic bottle.
- A pair of scissors to cut the bottle.
- A permanent marker.
- A ruler.
- Tape.
- Some peebles (small stones)
FIRST, ask an adult to help you cutting the bottle in two. Cut the mouth off at the top where the bottle starts becoming smaller.
NEXT place some stones in the bottom of the bottle. Turn the top upside down and tape around the edges where the two bottle parts meet.
Rain falls into the top of the gauge and collects at the bottom, where it can be easily measured. Try comparing the amount of rain to the length of time the shower lasted, was it a short and heavy rain shower or a long and light one?
