Creating a volcanic eruption
Ask students if they have ever seen a volcano before? Whether it was on television or in books that they have read before. Elicit responses from students. Ask, what happens when a volcano erupts? What do you think causes a volcano to erupt?
2 Direct Instruction
Today we are going to create a model of a volcanic eruption using the given materials placed at each group. I will show you a volcanic eruption on the smartboard (using the BrainPop app) so you can witness what happens in a volcanic eruption. Ask the following question:Do you think the lava of your model will flow in a straight path or ooze all over the earth?
3 Guided Practice
Students will work in their groups to create the volcano using the given material for each group. Teacher will circulate to each group asking the following questions about their findings: Why do you think the lava flowed on one side and not the other? What elements would you change in the experiment to get a different conclusion and why? How does an eruption of a volcano change the landscape of an area?
Students will share what happened in their experiment and their findings. Students will discuss any difficulties if any with their materials and the task.
