Volcanoes

# Learning objectives 1: Describe a volcanic eruption: on the ground and under the surface{.info} 2: Describe a volcanic eruption: in the air{.info} 3: Explain the impact of a volcanic eruption on humans{.info} # Volcanic eruption: On the Ground{.objective .objective1} In this section the different types of volcanoes that exist will be described. Their eruption and lava flow on the ground can be observed due to the pressure build up below the crust forcing lava to spill over the top of a volcano. Students will be able to explore the volcano, identify the type of volcano in the scene and observe the lava flow at ground level. Here they will be able to describe the lave flow and how far it may travel. # Volcanic Eruption: In the Air{.objective .objective2} In this section a volcanic eruption will be described and how it leads to lava bursting out of the crust with an ash cloud, both erupting upwards with a lot of force. Students will observe the eruption and describe what it looks like, and identify the material that will be erupting. Students should consider the distance the ash cloud may travel and the impact this may have. # Volcanic Eruption: Under the Surface{.objective .objective3} In this section why eruptions occur will be explained. It is understood that gradual build-up of magma below the crust can cause a large amount of pressure to build up that eventually leads to an eruption. Due to the quantity of magma build-up generates enough force to send an ash cloud hundreds of metres up in the air. Students should observe the internal section of the volcano and describe that the build-up of magma causes a build-up of pressure that is responsible for the eruption. # Impact on Humans{.objective .objective4} In this section it is described that many communities build settlements on the foothills of volcanic mountains. The fertile soil is a great location to farm crops as a source of food. However, there is a large risk to their safety in the event of an eruption. It is understood that volcanic eruptions can be destructive and extensive damage to farm land, homes and the very roads that can be used to travel away from a danger zone can occur. The scene will also show how an ash cloud travelling in the atmosphere may cause the air quality to be affected. This can often lead to the welfare of citizens to be at risk. Students should explore the foothills and identify the immediate risks an eruption may create. They should also describe how their air quality may be impacted by an ash cloud and the risk this creates for human health. # Teacher Resources ## Download Teacher Notes [](https://data.avncloud.com/activities/735214/files/Volcanoes%20Teacher+Notes.pdf?date=1626103271&size=799314&md5=55add357beb134c6ae8c341fd3f4145b) ## Student Quiz Answers Document [](https://data.avncloud.com/activities/735216/files/Volcanoes%20Teacher+Notes_02.pdf?date=1625845484&size=364883&md5=78c4c90f694716ce991b6a9125a1d460) ## Download Student Quiz Document [](https://data.avncloud.com/activities/735215/files/Volcanoes%20Teacher+Notes_03.pdf?date=1625845448&size=71264&md5=6b93519987428baa6d6d7fc2b2183bb7)
