How to Mark a Barometer Gauge

Making and marking a barometer gauge is a fun craft for children and adults alike. It helps everyone to understand how air weather conditions affect the air pressure. The trick to accurately predicting the weather is to ensure the tools are properly marked. Accuracy is important when marking your barometer gauge.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Barometer
• Barometer gauge
• Pencil or pen

1. Give the current day a barometric weather title. This means that you have to decide whether the day is sunny, rainy, cloudy, partly cloudy, snowy, and so on. Once you’ve given the current day and weather condition a title, you’re ready to begin marking your barometric gauge.

2. Take the barometer and the barometer gauge outside and place it on a stable surface. Make sure the barometer needle is close enough to the gauge so that you can accurately tell where on the gauge the needle is pointing.

3. Observe where the barometer needle points to or touches the barometer gauge and make a notation or pencil mark at that point.

4. Label the mark with the associated weather title. For instance, label it sunny if it’s a sunny day, or cloudy for a cloudy day and so on.

5. Repeat the above process for every weather condition. The barometer gauge will not be complete until you’ve done this for every possible weather condition.

Tips & Warnings

• Instead of using text to label the weather conditions, get a little creative and create several icons to represent each weather condition. Just make sure the icons are small enough to fit on the barometer gauge without overlapping.
• This activity is not for the impatient. It may take quite a while to experience every possible weather condition.
