Measure the Rainfall

Welcome to a Series of experiments using basic items around the house that help you measure the weather outside your own front door!

Each experiment also includes a quick trick for measuring that part of the atmosphere! Tag me on social media photos and data as you track the weather outside your own front door!


Measure the Rainfall


What you need:

  • 12” cyclinder, like a soda bottle
  • Rocks or pebbles
  • Water
  • Ruler

What to do:

  1. Fill up 12” clear cylinder with water.
  2. Even the bottom out with pebbles or stones.
  3. Use a rules to fill water to the one inch mark and make that your zero line…
  4. Put a thermometer stripe on the side to use for measurements.

Wait for rain! Check it everyday – evaporation can change your liquid level and you need to always have zero line. Make sure to place it on level ground with out any obstructions above the bottle. Measure and record and look for averages to compare with climate data.

Rain Gauge History: The capability to measure rainfall is important for many reasons, so it’s no surprise that rain gauges were one of the first weather-related instruments invented. They’re believed to have been used in India 2,000 years ago.

Moisture Effect… Quick trick to find out if there is water in the atmosphere — simply how it feels… and even condensationg! For example: humidity can make it feel different outside even when the temperatures are the same…. Like sometimes it’s humid and 60 degrees which feels muggy, with wind — 60 degrees can feel chilly and other times 60 degrees seems just right!
