Build a Rain Gauge from a Clear Container
Weather reporters tell us how much rain fell, but you can measure it yourself. All you need is a rain gauge, and you can make one at home with an adult's help.
Start with a clear plastic container that has straight sides, like a tall juice bottle with the top cut off. Straight sides matter, because they make the water rise by the same amount for each bit of rain. Tape a ruler to the outside, or mark lines up the side with a marker.
Next, pick a spot. Choose open ground away from trees, fences and roofs, so nothing drips into your container or blocks the rain. Set it where it will stand steady, and press it a little into the soil or place stones around the base.
After a rainy day, read the line where the water stops. Look straight at it, not from above. Write the number in a notebook with the date. Then pour out the water so the container is ready for the next storm.
If you check at the same time every day, your notes will show a pattern of wet and dry days.
