This activity uses simple materials and gives learners a chance to experiment with structures that can withstand an earthquake.
Two optional activities explore building damage by subjecting models to ground vibration on a small shake table. They experience how structures behave dynamically during an earthquake.
Learners explore earthquake hazards and damage to buildings by constructing model buildings and subjecting the buildings to ground vibration shaking similar to earthquake vibrations on a small shake table. Base isolation a powerful tool for earthquake engineering. It is meant to enable a building to survive a potentially devastating seismic impact through a proper initial design or subsequent modifications. The buildings are constructed by two- or three-person learner teams.
Students then apply basic design principles for TVES and make their own scale model that they think would fit will in their target community. Activity has great scope for both technical and creative design as well as practical application of math skills. Examples are from the Pacific Northwest, USA's most tsunami-vulnerable communities away from high ground, but it could be adapted to any region with similar vulnerability. Then: - Write a summary statement assessing strengths and vulnerabilities of essential services or infrastructure.
Module 7: Soils and a Systems Approach to Soil Quality part of Future of Food This module introduces what is meant by soil quality or soil health, indicators of soil quality, and the multiple cropping system approaches that can enhance soil quality for agricultural production. In the first Module 8: Pests and Integrated Pest Management part of Future of Food This module introduces three types of agricultural pests insects, weeds, and pathogens , integrated pest management, and some of the transgenic crop technologies developed to reduce crop pests.
