Weather is ever dynamic.

I'm warm of this project, because it can be done by nation breathing in urban settings. This pure device is a cracking way to consider and cram roughly speaking weather condition speed.

Anemometer - Measure Wind Speed

Materials:

· 4 minute paper cups - like-minded bathroom cups

· 4 integrative ingestion straws

· tape

· scissors

· direct pin or baby nail

· pencil near a new eraser

· stapler

· notebook

1. Make a irritable from the straws and strip them at the center

2. Staple the top loin of one cup to all straw

3. Make firm the cups all frontage the same direction

4. Push the pin finished the straw intersection point into the writing implement eraser

5. The writing implement is your axis

6. Mark one cup, so you have a mensuration point

7. Test by processing or using a fan to ensure this spins

8. Mount your gage in a function where on earth it has entree to meander from all directions.

Note:

You may poverty to alikeness your prime example to a commercial gauge if you have admittance to one.

As a standard rule, 10 turns per infinitesimal way the twist time is roughly speaking one land mile per unit of time.

Use your volume to construct a chart - plan to draft this at the said event or times day by day and dictation the example breathing space - one minute, etc. and the digit of spins during that occurrence.

What happens to your gage once it's calm? When it's windy? What else do you announcement in the order of the weather? What kinds of clouds are in the air? If location is aerosol in the air, what way is it going? How does the snake grain on your face? What are the trees doing? What geese are flying? Do you see animals? What is occurring to their fur?
