What can I use as a rain gauge?
Materials:
- Empty two-liter plastic bottle.
- Scissors.
- A few handfuls of clean pebbles, gravel, or marbles.
- Masking tape.
- Water.
- Ruler.
- Permanent marker.
- Rainy weather.
How do you make a simple rain gauge for kids?
Cut off the top of the bottle, just at the start of the widest point. Turn this top portion upside down on the bottle and tape it in place. Make sure the top is off. This will act like a funnel for the rain falling into the bottle.
Can you use a bucket as a rain gauge?
Rain gauges are used to measure liquid water depth and can be as simple as an open bucket with a consistent cross section throughout. Meteorologists however, use more accurate instruments and slightly more sophisticated gauges to measure rainfall.
What is a simple rain gauge?
Rain gauge is a meteorological instrument for determining the depth of precipitation (usually in mm) that occurs over a unit area (usually one metre square) and thus measuring rainfall amount. One millimetre of measured precipitation is the equivalent to one litre of rainfall per metre square.
Who invented rain gauge?
The first standardized rain gauge was invented in 1441 in Korea. In 1662 the first tipping bucket rain gauge was invented in Britain by Christopher Wren and Robert Hooke. The first systematic rainfall measurements were done between 1677 and 1694 by Richard Townley in Britain.
Where should I put my rain gauge?
The gauge should be installed 2-5 feet above the ground mounted on the side of a single post. The top of the rain gauge should extend several inches above the top of the mounting post. The mounting post should have a rounded, pointed, or slanted top to avoid upward splash towards the rain gauge.
Why is rain gauge placed below the ground?
The purpose of the grid is to reduce wind turbulence around the gauge and rain splash into the gauge. In high rainfall and poor drainage areas some arrangement has to be made to prevent the pit from flooding during heavy rain or snow melt as this could cause damage to the electronics of the gauge.
How accurate are rain gauges?
Rainwise tipping bucket rain gauges have an accuracy rating of 2% at 1.5” per hour. The National Oceanic and Atmospheric Association (NOAA) weather observer network, uses manual rain gauges with an 8 inch diameter opening. These are considered the most accurate, but are also more expensive.
Does a 5 gallon bucket make a good rain gauge?
5 gallons is about 2/3 of a cubic foot, and 2 inches is 1/6 of a foot. 2/3 cubic feet divided by 1/6 feet is 4 square feet, so 2 inches of rain falling over an area of 4 square feet is enough to fill a 5-gallon bucket.
How many types of rain gauge are there?
Measuring rainfall can be is primarily done in three different ways using three different types of rain gauges. The three major types of rain gauges are the standard gauge, tipping bucket gauge and weighing gauge.
Is code for rain gauge?
6.5 Raingauge of appropriate capacity as specified in IS 5225 shall be used to ensure the measurement of extremes of rainfall in the event of the observer being unable to take observations repeatedly on the day of such heavy rainfall.
What do you need to make a rain gauge?
All you need is an empty plastic bottle, the larger the better! I cut around the body of the bottle, about 5cm down from the top. We simply turned it upside-down and placed it inside the bottle, making sure it was pushed down and flush with the edges. Our bottle had grooves on it already and I just drew around them using a permanent marker.
How do you make a rain gauge out of soda bottles?
Pour in the pebbles in the bottom of the bottle. Soda bottles are never flat. Pour in the pebbles to even out the bottom and to keep the gauge from tipping over if it’s windy or the downpour is extremely heavy. Turn the top of the bottle into a funnel. Remove the cap from the top of the bottle and turn it upside down.
What to add to bottom of water bottle to measure rain?
Add 1⁄2 inch (1.3 cm) of sand to the bottom of the bottle. Adding sand to the bottom of the bottle will provide weight to keep the bottle from tipping over. It will also give you a level surface to measure water (the bottoms of most bottles are uneven).
How do you measure volume of rain water?
The rain water collecting bottle easily comes out of the bigger bottle. We can now uncap the funnel and either collect water in a baker and measure volume of the water collected or measure it directly. If you do not have a good measuring cylinder at hand you can use two identical small bottles.
What is rain gauge project for kids?
They can regularly measure the amount of rain and then record their findings in a journal. A rain gauge can be a do-it-yourself science project, a component of a weather station for kids or a device to help them estimate the water requirements of a garden.
What is a rain gauge made out of?
The simplest and most widely used rain gauges simply consist of a large cylinder, a funnel and a plastic measuring tube. As rain falls to the ground, it is collected by the funnel and travels to the plastic measuring tube.
How does a rain Guage work?
A rain gauge is a cylinder-shaped receptacle that a gardener anchors into the ground either with a stake driven directly into the ground or with a post driven into the ground. The rain gauge has measured increments marked on the sides of the receptacle in graduated measurements starting with zero at the bottom of the rain gauge.
