Introduction to Weather - WebQuest Matthew Miller & David Stoelzel EDU 505 Summer 2013

Introduction The weather is one of the few aspects in science that you will have a constant interaction with for the rest of your life. How many times have you wanted to know what the weather was going to be in order to figure out what to wear or if you were going to be able to go to an outdoor event? By learning the different factors that go into changing the weather, you will be better prepared for it.

Task Your task within this WebQuest is to walk through several websites that will introduce you to different aspects of the study of weather. You will also be answering several questions as you go through this WebQuest.

Process Starting on the next slide, follow the steps laid out to complete this WebQuest. As you go through this WebQuest answer the questions that follow. Base your answers on the information found on the websites given.
