This is not a fruit fly

 

Scientists have used fruit flies, or the scientific genus Drosophila, as an animal model for experimentation and the study of genetics for a long time for many reasons.  You too can catch, learn to raise and study Drosophila.  Fruit flies offer an exceptional opportunity to learn about insect lifecycles, how to maintain cultures of insects, genetics and animal behaviors.  [NOTE: I know that this is not a fruit fly, but Popillia japonica Newman]

White Trout Lily

 

 

 

 

 

We now know what to measure in order to make weather observations but what should we do with those measurements?  In this final part we activities that involve watching the weather.  These projects can be as short as a day or as long as a lifetime and can provide valuable information to meteorologists worldwide.

Snowy Scene

 

 

 

In this part we talk about three more weather observations that we can make, wind speed, direction and the duration of sunlight.  Making these measurements are a little more involved and good for someone looking for a project as commercial instrumentation is likely to be out of the price range of most people.  These measurements round out the observations that we have previously discussed and help with making a complete record of the daily weather.

Picture of Happy Clouds

 

 

We left off our discussion of the weather talking about recording rainfall and the temperature.  We continue our discussion talking about barometric pressure and relative humidity.  These two parameters can tell us much about the direction the weather is heading, whether we will have fair skies or rainy nights.

Clouds over the Tower

 

 

If you watch the morning or evening news, unless there is a major tragedy occurring you probably are most interested in the weather forecast.  In our modern world the weather can have much larger effects than whether you have your picnic in the park or you take the umbrella with you when you go out.  Strong storms can cause travel delays and even devastate cities.  Too much or too little rain or cold can damage crops.  Even excessive heat can cause illness and death.  What can we learn about the weather?
