How To Make A Rain Gauge

1st) Assemble the gauge by putting the funnel securely onto a container that's large enough to collect the amount of rain you would normally get in your area without overflowing.

- Index card
- Pencil with eraser
- Tape
- "How to Make a Wind Vane" directions worksheet (provided below)

Making a Wind Vane:1. Cut out both the point and tail of an arrow out of an index card.
2. Tape the tail on one end of the straw and the point onto the other.
3. Push the pin through the middle of the straw.
4. Stick the pin into the eraser of the pencil. Make sure the straw can turn freely.

Today, we made the rain gauge. A rain gauge is an weather instrument that is able to measure rainfall.
These are the steps to measuring the rainfall at your location:

1st) Measure the widest inside diameter of the funnel, divide that by 2.


2nd) Square that number (multiply it by itself) then multiply by 3.142 to get the area of the top of the funnel


3rd) Divide the number you came up with by 10. This gives you the factor to multiply by when you are working out how much rain has fallen in millimeters.

The 4th picture from the bottom to the top shows the Wind Vane that we made. A wind vane is an instrument, something like the weather cock. It shows the direction that the wind is blowing at different points of time and locations.
