Make a simple rain gauge to observe how much it rains!

Material List

  • 2Fill up the bottom part of the bottle with pebbles or sand.
  • 3Use a ruler to mark the bottle every inch or centimeter with a black mark.
  • 4Put the top part of the bottle that was cut off upside down over the opening.
  • 5Use four paper clips to hold it together.

How It Works

When it rains, the rain will fall into the rain gauge. The markings on the side can help you see how much rain falls on certain days or in certain months. Rainfall amounts from previous years are just one of the things weather scientists use to help predict the weather by looking at patterns.
