Natural Disasters - Where and Why?
1 Hook/Tuning in to Learning
- Display various headlines about volcanoes and earthquakes globally from Newsela Articles
"Lost Cities: Pompeii, preserved by disaster, risks ruin all over again"
"Hot lava flowing into the cool ocean off Hawaii gives quite a show"
"Strong earthquake hits Mexico; at least 90 people are dead"
"Disaster education centers in Japan provide lessons in survival"
Students use the Visible Thinking Routine: Connect Extend Challenge using the following prompts:
How are the ideas and information presented
CONNECTED to what you already knew?
What new ideas did you get that EXTENDED or pushed your thinking in new directions?
What is still CHALLENGING or confusing for you to get your mind around? What questions, wonderings or puzzles do you now have?
Share thoughts as a whole class
- Students examine headlines and complete the visual thinking routine
- Share initial thoughts with the whole class
2 Core Learning - What Do I See/Think/Wonder?
- Instruct half the class to turn on the volcano layer in Google Earth
- Instruct the other half to turn on the earthquake layer
- Direct students to hover over Japan (Pacific Ring of Fire)
- After students have had time to complete their See/Think/Wonder students join up with someone from the other group to compare
- Students should identify that there is a linear pattern and the vocanoes and earthquakes overlap
- Students turn on their given layer in Google Earth
- Hover over Japan
- Students complete the Visual Thinking Routine "See/Think/Wonder"
- When they are looking at Google Earth, what do students see? Record observations
- What do they think? What ideas do they have about patterns they see?
- What do they wonder? What questions do they have?
3 Consolidation - Why Is This Happening?
- Students share observation about what they noticed with the whole class
- Why do these patterns exist?
- Teacher explains to students that these patterns exist because of plate-tech-tonics.
- The crust of the earth is composed of plates which float on the mantle.
- These plates meet at fault lines which when they pass one another can cause natural disasters such as volcanoes and earthquakes
- This is why the natural disasters have occured in a line
- Students can look for other global patterns
