# Lesson:What's the Problem?

</

### Summary

This lesson introduces students to the Asteroid Impact unit and its engineering challenge: an asteroid is on course to impact the Earth and we must design the location and size of underground caverns to shelter the people from an uninhabitable Earth for one year. Students read the president's memo to receive their "marching orders." They form teams, become familiar with the maps, and complete investigative worksheets.
This engineering curriculum meets Next Generation Science Standards (NGSS).

### Engineering Connection

Engineering teams always begin the design process by defining the problem. This process involves identifying, through group discussion and research, the technical, financial and social criteria for successful solution design.

### Learning Objectives

• Read, understand and identify a problem.
• Hypothesize, through group discussion, what information might be required to solve the problem.
• List design constraints (social, environmental, financial, etc.) that must be considered to adequately complete a functioning solution to the problem.
• Learn basic map reading skills such as understanding a legend or key, and using a map scale to determine distances.

### 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.

### Introduction/Motivation

Students are called by the president to design underground caverns to protect and save people from an impending asteroid impact. The motivation is provided in the President's Memo

### Associated Activities

• What's the Problem? - Students learn of the impending asteroid impact scenario, form teams and begin to study the situation. A simulation shows them the potential for destruction and disaster. They look at maps and complete a worksheet and homework assignment to help them define and understand the problem.

### Assessment

Examine the worksheet to gauge students' comprehension of the engineering challenge. Help students generate a list of design constraints, such as the number of people, size of the asteroid, the length of the expected stay in the caverns and environmental considerations. Prompt them to find clues about constraints on their graphic organizer. Students refer back to this list to complete the activity, so a collaborative list on display at the front of the class may be most appropriate. Quiz them on the President's Memo. Review their homework assignments when turned in.

### Lesson Extension Activities

Have students read the CRFAO Briefing and:

• Look up one of the internet websites and write a report.
• Construct a model of the solar system with an asteroid belt.
• Write a paragraph about the importance of studying asteroids.
