This project-based scientific inquiry project: **Earthquake and Boise River Bridge Design** is centered on researching different types of bridges, various aspects of earthquakes, and seismic safety features of bridges. In this project, students work in small groups to explore different bridge types, the destructive aspects of an earthquake, and the safety features for bridges that could resist earthquakes. Then students will design an earthquake-tolerant bridge and test their design with an earthquake simulator. To develop computational thinking and an understanding of STEM subjects, students from 4th, 5th and 6th grade will work in small groups of six, with one in-service teacher and one pre-service teacher, twice a week for eight weeks in a community centers after-school program.

Please refer to the weekly activities (such as **Week 1 Session 1** in the left sidebar and **Resources** from the sections below) for detailed information on how to use this project either in a classroom or an informal setting such as in community centers' after-school programs. The twice weekly sessions were originally designed to be 90 minutes in length, including a 10 minute break in the middle of the session. See photos of prior implementations on the projects' photo pages.

How can we build a bridge for the Boise River that is strong enough to resist earthquake forces?

A teacher asks the following questions to prompt students thinking about an “earthquake”, and allows the students to share their experiences before showing video about earthquakes.

What is an “earthquake’?

Have any of you experienced an earthquake before? What does it like?

Have any of you watched any movies about earthquake? What does it like?

Does anyone know what is the cause of an earthquake?

Watch Dr. Andre Filiatrault’s earthquake video about what causes earthquakes (5:49 minutes).

Students (in a group of 2-3) will independently research on the topics of “what is an earthquake?” “What causes earthquake?” and some other scientific facts about earthquake. Some guiding questions are as follows:

What is an earthquake?

What causes earthquakes? And where do they happen?

Why does earth shake when there is an earthquake?

How are earthquakes recorded?

How do scientists measure the size of an earthquake?

**What is an earthquake?**

**How is an earthquake caused?**

(students presentations need to closely related to the sub questions and learning outcomes)

**Suggested approach**: Half of the students hang their posters up, and present their research to the remaining students. The poster items will reflect on earthquakes and their causes. After 10 minutes, the two groups of students switch roles with the original presenters who become the audience and the other half of the students who hung up their posters for their presentations. Students can also use Google slides, however the teacher needs to remind students of the limited time available to work on their poster/slides.

Using the Problem Solving Process Diagram, the teacher will ask students to identify what kind of problem solving skills/process/computational thinking they used in this session and explain how they used it. The following are some sample questions that can guide the debrief.

What did I learn today?

What problem solving skills/processes or CT components in this diagram did I use today?

How did I use the problem solving skills/processes/CT components?

How can we build a bridge for the Boise River that is strong enough to resist earthquake forces?

A teacher asks the following questions to prompt students thinking about an “earthquake”, and allows the students to share their experiences before showing video about earthquakes.

What is an “earthquake’?

What do we know about earthquakes?

How can we detect earthquakes? And why?

How do scientists measure the size of earthquakes?

Watch Dr. Andre Filiatrault’s earthquake video about what causes earthquakes (5:49 minutes).

Students will work in groups of two to research the damages of earthquake as well as other earthquake effects:

Why does earth shake when there is an earthquake?

What are the damages of an earthquake?

What are earthquake effects?

How can we detect an earthquake?

**What is an Earthquake caused**

**About Earthquake Effects**
