1. Outdoor Thermometer
You must purchase this item. Hang it someplace where it is not in direct sunlight. This will allow your thermometer to get a more accurate measurement of the air temperature.
2. Rain Gauge
- Wide-mouth jar (glass or plastic)
- 6-inch or regular ruler
- Glue (optional)
- Marker (optional)
- Masking tape (optional)
- Use a jar that has as wide an opening as possible. It can be either glass or plastic.
- Glue an inexpensive six-inch ruler to the outside of the jar, or use a regular ruler and a permanent marker to draw the measurements on the jar itself. If the jar is glass, stick a piece of masking tape on its side, and draw marks on the tape.
- To measure rainfall at your house, be sure to place your rain gauge in an open space, a little off the ground and away from trees if possible.
