Students build miniature model cities using sugar, bouillon and gelatin cubes. The cities are put through simulated earthquakes to see which cube structures withstand the shaking movements the best.
This engineering curriculum aligns to Next Generation Science Standards (NGSS).

Engineering Connection

In many areas of the world, earthquakes cause buildings to fall and many lives to be lost. Civil engineers design structures to be able to withstand the force of earthquakes. To do this, they must understand how the movement of the Earth affects structures, and what types of materials are best to use in earthquake zone construction.

Learning Objectives

  • The effect of earthquakes on structures.
  • The importance of strong buildings to prevent destruction by earthquakes.
  • How the epicenter of an earthquake affects buildings.
  • Different materials used in the construction of buildings.

Educational Standards

Each TeachEngineering lesson or activity is correlated to one or more K-12 science, technology, engineering or math (STEM) educational standards.

All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standards Network (ASN), a project of D2L (www.achievementstandards.org).

In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics; within type by subtype, then by grade, etc.

Have you ever been in an earthquake? What happens during an earthquake? (Listen to student stories and explanations. If students are unfamiliar with earthquakes, show them YouTube videos taken during earthquakes.)

During an earthquake, energy travels through the Earth and can cause damage to buildings and other structures. The amount of damage caused by an earthquake depends on several factors, such as the strength of the earthquake, how long it lasts, and where it happens.

What is an epicenter? (Listen to student ideas.) The epicenter of an earthquake is the point on the Earth's surface directly above where an earthquake starts, or where the shaking begins. Damage is typically greatest at the epicenter.

What can we do to keep people from being hurt in earthquakes? (Listen to student ideas.) Well, we cannot prevent earthquakes; they're a natural phenomenon of the Earth. But engineers have lots of ideas about how we might make our buildings more safe so they don't fail during earthquakes. For example, the most modern skyscrapers are made of more flexible materials so that they bend and sway during earthquakes and do not fall down easily.

Let's do a little experiment today and learn more about designing structures to be more earthquake resistant.


Before the Activity

  • Buy or assemble the materials.
  • Make copies of the Testing Worksheet.
  • Prepare the gelatin cubes.

With the Students

  1. Discuss with the class what an earthquake is and what the epicenter of an earthquake is. Divide the class into small groups or pairs of students. Give each group a box bottom and a worksheet.
  2. Using the pencil and ruler, have students create grids on their box bottoms by drawing 4 vertical lines and 5 horizontal lines, with each line about 5-cm apart. Label the vertical lines 1st Avenue, 2nd Avenue, 3rd Avenue, etc., and the horizontal lines A Street, B Street, C Street, etc. This is our Earthquake City.

  3. Save student teams build three sugar cube skyscrapers, each five sugar cubes tall. Place these skyscrapers at the following corners: A and 1st , B and 2nd , C and 3rd.
  4. To show that earthquakes can cause damage to buildings, have each team simulate an earthquake by tapping on the corner of E and 4th with the eraser of a pencil. Have them continue to tap until at least one cube from each skyscraper falls. Ask: Which skyscraper falls first? In a real earthquake, do you think damage happens more in one place than another? Where would the most damage happen?
  5. Have students repeat step 4 again (earthquake simulation), but use different strength taps, representing hard vibrations and soft vibrations. Determine how many hard or soft vibrations it takes to knock over buildings that are different distances away from the epicenter.
  6. Have students record results in the chart on the worksheet, noting the skyscraper locations and when they fell.
  7. Now give students time to experiment with different types of cubes. Encourage them to create skyscrapers of different heights and from a mix blocks.
  8. After they have had time to experiment with the different types of blocks, have each group build a city of skyscrapers. The cities may be as large as they wish, but must have at least five skyscrapers of different heights.
  9. Once the cities are completed, go around to each group and tap with your pencil at a corner in the city to test how earthquake resistant they are.
  10. After the cities have been tested, and students have put away materials, lead a class discussion to share results and discoveries.


Use the attached rubric to evaluate students for performance, teamwork and understanding.

Rubric for Performance Assessment (pdf)

Rubric for Performance Assessment (doc)

Graphing: Have students create two bar graphs - one showing the amount of taps necessary to cause each type of building to fall, and one showing the distance each type of building was from the tapping point. Then use these graphs to discuss how the type of building and its distance from the tapping point affect how the building reacts during an earthquake.

Investigating Questions

  • Why is it useful to build skyscrapers using different materials?
  • Which materials were the best to use for taller buildings?
  • Which cubes were the most earthquake resistant? Why?
  • Which skyscrapers fell first in the earthquakes? Where were they located in respect to the epicenter of the earthquake?
  • What happens when the top of a skyscraper is heavier than the bottom, or when the bottom is heavier than the top?
