Investigation 41
Risk Perception
Synopsis: Students are asked to rank order the fifteen leading injuryrelated reasons why boys and girls visited emergency rooms. Students then compare their perception of the risks with the actual risks and realize that their perceptions are not always the same as the actual risks. Students then explore the impact that this difference might have on the allocation of resources to prevent visits to the emergency room for a particular reason.

SCIENCE  
Unifying Concepts and Processes K12  
Conceptual and procedural schemes unify science disciplines and provide students with powerful ideas to help them understand the natural world. Because of the underlying principles embodied in this standard, the understandings and abilities described here are repeated in the other content standards. 

As a result of activities in grades K  12, all students should develop:  
1: Science as Inquiry  
Inquiry requires that students combine processes and scientific knowledge as they use scientific reasoning and critical thinking to develop their understanding of science. Engaging students in inquiry helps students develop an understanding of scientific concepts, an appreciation of "how we know" what we know in science, an understanding of the nature of science, the skills necessary to become independent inquirers about the natural world, and the dispositions to use the skills, abilities, and attitudes associated with science. 

6: Science in Personal and Social Perspectives  
An important purpose of science education is to give students a means to understand and act on personal and social issues. The science in personal and social perspectives standards help students develop decisionmaking skills.

1: Health Promotion and Disease Prevention  
Students will comprehend concepts related to health promotion and disease prevention. 

2: Health Information, Products and Services  
Students will demonstrate the ability to access valid health information and healthpromoting products and services.


3: Reducing Health Risks  
Students will demonstrate the ability to practice healthenhancing behaviors and reduce health risks.


4: Influences on Health  
Students will analyze the influence of culture, media, technology, and other factors on health.


6: Setting Goals for Good Health  
Students will demonstrate the ability to use goalsetting and decisionmaking skills to enhance health. 

7: Health Advocacy  
Students will demonstrate the ability to advocate for personal, family, and community health.

LANGUAGE ARTS  
Grades K  12  
1: Reading for Perspective  
Students read a wide range of print and nonprint texts to build an understanding of texts, of themselves, and of the cultures of the United States and the world; to acquire new information; to respond to the needs and demands of society and the workplace; and for personal fulfillment. Among these texts are fiction and nonfiction, classic and contemporary works. 

6: Applying Knowledge  
Students apply knowledge of language structure, language conventions (e.g., spelling and punctuation), media techniques, figurative language, and genre to create, critique, and discuss print and nonprint texts. 

7: Evaluating Data  
Students conduct research on issues and interests by generating ideas and questions, and by posing problems. They gather, evaluate, and synthesize data from a variety of sources (e.g., print and nonprint texts, artifacts, people) to communicate their discoveries in ways that suit their purpose and audience. 

11: Participating in Society  
Students participate as knowledgeable, reflective, creative, and critical members of a variety of literacy communities.

SOCIAL STUDIES  
Grades 5  8  
Economics  
1: Scarcity  
Productive resources are limited. Therefore, people can not have all the goods and services they want; as a result, they must choose some things and give up others. 

3: Allocation of Goods and Services  
Different methods can be used to allocate goods and services. People acting individually or collectively through government, must choose which methods to use to allocate different kinds of goods and services.

TECHNOLOGICAL LITERACY  
Grades K12  
3: Technology Productivity Tools  
Students use technology tools to enhance learning, increase productivity, and promote creativity. 

Students use productivity tools to collaborate in constructing technologyenhanced models, prepare publications, and produce other creative works. 

5: Technology Research Tools  
Students use technology to locate, evaluate, and collect information from a variety of sources. 

Students use technology tools to process data and report results. 

Students evaluate and select new information resources and technological innovations based on the appropriateness for specific tasks.
