What is the rain gauge? The rain gauge is used to measure rainfall. We made it with a plastic bottle and set it outside. We will check it a week later to estimate how much rain we got!

Hike Your Knowledge:  How to Measure Rainfall

We watched this video’s instruction and followed it. It was clear and straightforward.

Step by Step

Cut the neck of the bottle. I cut about 1/3 part from the top. I am not good at cutting straight with a utility knife, so I marked with a sharpie first. (Optional)

Done!

We collected some pebbles from outside.

My son put a tape above the level of the pebbles. According to the video we saw, it will act as a starting point.

Pour some water till the starting point. The water is not clear, but it is OK.

Flip the other part into the bottle like a funnel.

Done! Then we can put this rain gauge outside and measure rainfall!
