The purpose of this lesson is to introduce students to the basic elements of our Earth's crust: rocks, soils and minerals. They learn how we categorize rocks, soils and minerals and how they are literally the foundation for our civilization. Students also explore how engineers use rocks, soils and minerals to create the buildings, roads, vehicles, electronics, chemicals, and other objects we use to enhance our lives.
An engineering and design lesson for middle school (our 7th grade standards).
In the aftermath of a natural disaster, can you engineer a device that will keep medicine within a 40-60°F range using natural resources from the biome you live in, and/or debris created by the disaster for three days, until the Red Cross can arrive?
You are a team of relief workers in __________________after a major earthquake/tsunami has occurred. Your team lead as just told you about a young women with diabetes has been injured and needs insulin to be delivered __________ miles away (no open roads). Your team will need to research, design, and build a portable device to keep the insulin between _____ and ______ °(F/C) for _____ days. Once you return you will present the effectiveness of your device to your lead and a team other relief workers showing your both your design/device and explaining the process.
Students learn about the structure of the earth and how an earthquake happens. In one activity, students make a model of the earth including all of its layers. In a teacher-led demonstration, students learn about continental drift. In another activity, students create models demonstrating the different types of faults.
Ground shaking is the primary cause of earthquake damage to man-made structures. This exercise combines three related activities on the topic of shaking-induced ground instability: a ground shaking amplification demonstration, a seismic landslides demonstration, and a liquefaction experiment. The amplitude of ground shaking is affected by the type of near-surface rocks and soil. Earthquake ground shaking can cause even gently sloping areas to slide when those same areas would be stable under normal conditions. Liquefaction is a phenomenon where water-saturated sand and silt take on the characteristics of a dense liquid during the intense ground shaking of an earthquake and deform. Includes Alaska and San Francisco examples.

Students learn how engineers construct buildings to withstand damage from earthquakes by building their own structures with toothpicks and marshmallows. Students test how earthquake-proof their buildings are by testing them on an earthquake simulated in a pan of Jell-O(TM).
