1. Composite Volcano This type has alternate layers of ash and lava. Sometimes there can be different layers of lava on top of each other, but with years in between eruptions. Using different coloured text for effect and then adding lines which stretch from the source (the text) to the corresponding location on the sketch and the photograph.

2. Hazards Water and sulpher gas mix to create fumaroles. Add features and arrows, first the underground, then ash related, lava related and, finally landslides and lava domes. This slide using arrowed lines to good effect, stretching them from the relevant start position. A mouse click reveals the text which introduces the volcanic feature and is followed by the feature highlighted by text and lines appearing in a timed sequence without the need to click the mouse, until the next feature is studied. The text is blanked out by a black rectangle to create a clear background for the next text box. If you wish to place the animation before the explanatory text then enter Custom Animation and change the order by moving the text below the associated object, text boxes and lines.Add features and arrows, first the underground, then ash related, lava related and, finally landslides and lava domes.

3. Volcanoes: Exercise Use the list below to label the diagram. Lava Eruption Cloud Acid Rain Magma Bombs Mud flow Lava Dome Landslide Fumaroles Ground Water Pyroclastic Flow This exercise is not interactive in PowerPoint, but the image could be repeated in different software which is designed for this purpose. The image and text could become an activity in an interactive whiteboard file or in a drag and drop exercise such as may be created using JMatch from the Hot Potatoe suite of software from Half Baked Software.
