Grey Olltwit's Global Environmental Issues

An animated, interactive, learning journey through three environmental topics, the Ozone Layer, the Greenhouse Effect and Acid Rain. After each topic there is a multiple choice quiz about the presentation you have just seen. On the first screen choose from one of the three topics by clicking on either The Ozone Layer, Greenhouse Effect or Acid Rain. In each of these topics you are led through a simple animated journey describing the processes involved and giving extra information on the likely effects in the longer term. You control the speed of the journey through each topic by clicking on the Next button when it appears in a text information box giving details about that particular part of the process. At the end of each topic there is a 10 question multiple choice quiz based on the information in the previous presentation. The correct answer to each question is contained in one of three buttons below the question. A certificate is presented at the end of each quiz.
