Building Stability and Acceleration Concepts

The video tutorial guides students in designing earthquake-resistant buildings using the Google Science Journal app to measure acceleration. It demonstrates how attaching a phone to a model building can simulate an earthquake and measure acceleration. The tutorial explains the concept of base isolation systems and suggests improvements using classroom materials like rubber bands and padded stoppers. It encourages students to experiment with different designs to reduce peak accelerations during shake tests. Additional resources are available at Science Buddies.

What is the primary tool used in this project to measure acceleration?

• A physical accelerometer

• Google’s Science Journal app

• A seismograph

• A ruler and stopwatch

What happens to the acceleration when the model building is attached directly to the ground and shaken?

• It shows high minimum and maximum values

• It decreases significantly

• It remains constant

• It shows no change

How do markers acting as rollers affect the building's acceleration during a simulated earthquake?

• They have no effect

• They increase the acceleration

• They reduce the acceleration

• They cause the building to collapse

What is a potential downside of using rubber bands to keep the building centered?

• They can increase oscillations if too tight

• They can make the building too heavy

• They can cause the building to float

• They can make the building too rigid

What is one method suggested to prevent the building from rolling off the tracks?

• Using magnets

• Using glue

• Adding more rollers

• Adding padded stoppers

What is a potential issue with placing stoppers too close to the building?

• They can cause the building to shrink

• They can make the building too stable

• They can increase acceleration spikes

• They can cause the building to tip over

What alternative method is suggested for suspending the house?

• Using metal rods

• Using plastic sheets

• Using straws and string

• Using wooden planks

What is the main goal for students in this project?

• To use the most materials

• To build the tallest structure

• To reduce peak accelerations during a shake test

• To create the most colorful design

Where can students find additional resources and instructions for this project?

• In a library

• In a textbook
