Students also explore why understanding these natural events is important to engineers and everyone's survival on our planet. In this lesson, students are introduced to a multitude of geologic events and how engineers learn from these to secure our survival on Earth.
- GLE 0507.2.3
- Establish the connections between human activities and natural disasters and their impact on the environment.
- GLE 0507.7.1
- Compare geologic events responsible for the earths major geological features.
- GLE 0507.T/E.4
- Recognize the connection between scientific advances, new knowledge, and the availability of new tools and technologies.
Alignment of this item to academic standards is based on recommendations from content creators, resource curators, and visitors to this website. It is the responsibility of each educator to verify that the materials are appropriate for your content area, aligned to current academic standards, and will be beneficial to your specific students.
After this lesson, students should be able to:
- Differentiate between a natural disaster and a natural hazard.
- Name at least three different natural hazards.
- Explain why engineers care about natural disasters.
- Have students research specific natural disasters, making posters that describes them. Have them talk about what natural hazard caused each disaster as well as the effects and what might have been done to prevent or minimize the impact of the disaster.
- As a side activity, have students learn more about potential and kinetic energy as they design and build a way to safely and accurately deliver relief goods (represented by an egg) to people in a natural disaster area with no road access. Similar to real-world engineering design teams, students must design their devices with constraints such as limited materials. This Bombs Away! activity is targeted for sixth-grade studens but may be suitable for grades 4-8.
- Ask students to think about the types of natural disasters that might occur in the region in which they live. Then, imagining that a natural disaster occurs in their community, what have engineers created that would help students survive the dangerous situation? For example, if you are safe during a blizzard, what keeps you safe? Engineer-designed examples might include: Strong roof, insulated walls, heating system, lighting, communication devices (radio, television, phones), indoor plumbing and electricity, stoves and refrigerators, warm clothing made with modern fabrics, weather predicting and warning devices, safe vehicles, etc. Have them summarize in a one-page paper.
