Lesson Introduction: Engineering Resilient Structures Against Earthquakes

Objective

The goal of today's lesson is to explore how different structures in urban areas can be designed and built to withstand earthquakes. By understanding the principles of engineering and geology, we will engage in creative thinking to propose our own earthquake-resistant designs.

Hook: The Shake Table Challenge

Activity Overview

Imagine you're an engineer tasked with designing a new building in a city located on an earthquake fault line. How would you ensure that your structure can survive the unpredictable shaking of an earthquake? To kick off our lesson, we will begin with a Shake Table Challenge.

Materials Needed

1. Shake Table: We will use a simple shake table (which can be made using a cardboard base, marbles, and a piece of plywood) to simulate earthquake movements.

2. Building Materials: Gather everyday materials such as straws, marshmallows, tape, and cardboard.

3. Design Sheet: Each group will receive a design sheet outlining the criteria for their building’s earthquake resistance.

Instructions

1. Group Division: Split the class into small groups. Each group will act as a design team of engineers.

2. Design Phase: Using the materials provided, teams will have 15 minutes to design and construct a model of a building they believe can withstand an earthquake.

3. Shake Test: After the construction phase, each group's building will be placed on the shake table. As the table is shaken, we will observe which structures withstand the shaking and which ones fail.

Discussion Points

• Observation: What designs performed best? Why do you think they were successful?

• Engineering Principles: Discuss concepts such as base isolation, materials used, and structural integrity.

• Real-World Applications: How do engineers today design buildings to ensure safety during earthquakes?

Transition to Lesson Content

Having now experienced the challenge of creating earthquake-resistant structures firsthand, we will delve into the scientific principles and engineering practices that inform our designs. Throughout this lesson, we will explore:

• The geology of earthquakes
• Engineering concepts such as flexibility, strength, and materials
• Case studies of buildings that successfully withstood past earthquakes

Prepare to use your curiosity and creativity as we engage with today’s lesson on building a safer urban environment!
