Welcome to class number three! We are going to discuss the remaining "suspect" in our climate change mystery. Be sure to come today so you can know what the answer is.
During the second part of our class you will be conducting an experiment to investigate key variables in our later discussion about microscale climate and the phenomena of the urban heat island. Please bring paper and pen so you can take notes during the experiment. I have 2 infrared thermometers and one small weather station. You will break into 3 groups to collect microscale measurements of surface and air temperatures around the La Salle University campus. Take only outdoor measurements. I encourage to you walk around to collect data at various locations such as the courtyard, steps, side walks, futbol field, grass areas, under trees, and flower beds. For those using the IR thermometer note down the surface and temperature. For those collecting data with the weather station, collect air temperature, relative humidity, and wind speed. Write all of your data on your paper and we will talk about the measurements during Friday's class.
You should review today's lecture slides for a summary of our discussions.
In our discussion about the Earth's orbital cycles we looked at an interactive website. I encourage you to check this out and I think it will help you appreciate how the three different planetary cycles can affect the Earth's climate.
