COVID-19 Advisory: WSU Extension is working to keep our communities safe. All Extension programming is being provided virtually, postponed, or canceled. Effective March 16, 2020, WSU Extension county offices and WSU Research & Extension Centers will be closed to the public. We are available via email, phone, and webconference.
Weather Watchers – Explorer: Skill Level One
EXPLORER – Skill Level: One
Measuring Temperature, Wind and Rain
Objective: Collect consistent and accurate data collection with self created data tools Science Skills: data collection, confirming data against multiple sources Life Skills: critical thinking
Ask youth if they remember the weather a month ago on a specific day. Why would knowing / predicting the weather be important? How does having specific records of past weather help us? How do we make predictions?
What You Will Need
– Observation Log
– Outdoor thermometer
– Coffee can
– Clear jar with flat bottom (spaghetti/olive jar)
– Wide clear tape
– Two liter plastic bottle
– Construction paper
– Push pin
– Pencil with eraser
Activity: Weather Logging Explain to youth that a good observation log would include environmental records such as temperature, wind and precipitation. Ask why that information could be important.
What would be important about collecting a data of the weather? (ex: daily highs and lows, checking against forecasts, collecting at the same time each day).
Youth can use the same calendar from other activities or an observation log to record their information.
Comparing their own data with that of a qualified source will help raise worthwhile questions.
There is no shortage of weather web sites available online. We recommend using the WSU AgWeatherNet (linked in Explore More) to get accurate readings for your county. Youth can check their data against the data available on the Washington Map by rolling their cursor over the weather stations near their location. Checking online data that is not a high or low should be done at relatively the same time each day to confirm accuracy.
On windy days practice making wind assessments both from beaches and on land using the Beaufort scale. (see below)

Fahrenheit to Celsiusand Back Again
Formula: Convert Fahrenheit to Celsius
1. Subtract 32 degrees from the Fahrenheit temperature.
2. Multiply by 5.
3. Divide by 9.
Formula: Convert Celsius to Fahrenheit
1. Multiply the Celsius temperature by 9.
2. Divide by 5
3. Add 32
Asking the Right Questions:
How do we explain differences in our data? When do high temperatures generally happen? When do low temperatures generally happen? How consistent were we on collecting data at the same time each day? How accurate is our data compared to other sources?
