Science Fair Project Clouds and Weather By: Keith Taylor Class 707 Introduction Weather is apart of our everyday lives. It’s something that needs to be monitored because weather can change in the blink of an eye like what’s going on in the North Pole with greenhouse gasses and global warming. Background Information • To start off, clouds and weather are apart of our everyday lives. We have to acclimate to the changes of weather, and the weather causes us to change what we wear everyday. • Clouds are a group of tiny liquid water droplets hanging in the air. There are a plethora of types of clouds and they can either bring precipitation or just a nice day. Cirrus or cirro (prefix) are wispy, feathery, transparent clouds made of ice crystals that range high altitude. Another type of cloud is cumulus or cumulo; they are puffy clouds that range middle-altitude. In addition, nimbo or nimbus added to the front of a cloud name means rain cloud. Lastly, there is the stratus cloud which is what we see on a daily basis. They are sheet like clouds ranging low-altitude. Background Information Cont. • Weather is the conditions of the atmosphere at a particular time and place. Weather changes when a new air mass moves over your area. There are four types of air masses. One of those types is called maritime tropical, air mass that forms over the ocean near the equator with warm and moist air. Maritime polar is the complete opposite of maritime tropical. Another type of air mass is continental polar, which air mass is dry and cool. Lastly, continental tropical is the fourth air mass with a warm dry climate. • In conclusion, weather is apart of our everyday lives. It’s something that needs to be monitored because weather can change in the blink of an eye like what’s going on in the North Pole with greenhouse gasses and global warming. Problem and Hypothesis • How do clouds and weather relate to global warming? – Clouds and weather relate to global warming because they are the effect of it. Greenhouse gasses are polluting the air and making the weather and clouds react to it with natural disasters and storms. Purpose • The purpose of this inquiry is to explain what weather can bring us on an everyday basis, and how weather instruments are used to record down weather factors. Weather Instrument • The instrument I chose was a barometer. A barometer measures air pressure which is the measure of the weight of air pressure pressing down on a given area of Earth’s surface. The units used for air pressure is millibars.

Conclusion • Conclusion • Weather is apart of our everyday lives and we need to keep track of it so we can acclimate to its changes. We can keep track of weather using the different weather instruments. Bibliography • http://facstaff.gpc.edu/~pgore/Earth&Spac e/airmasses.html • Brunkhorst, Bonnie J. Science Saurus.
