Investigation 2-1
The 2 X 2 Table

Synopsis:  Students examine the results of a hypothetical study to determine if a medication prevents acne.  In doing so, students uncover that a scientific study needs to examine not only people who are exposed to the medication, but a group of people who are not exposed to the medication.  Students construct 2x2 tables and realize that when they study how an exposure and an outcome (disease) are distributed, every person in the study population fits into one of the four cells of the 2x2 table.  Students also realize that the way an exposure and an outcome are distributed in a group of people can be expressed mathematically.

SCIENCE
 
Unifying Concepts and Processes K-12

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 decision-making skills.

 
7: History and Nature of Science

In learning science, students need to understand that science reflects its history and is an ongoing, changing enterprise. The standards for the history and nature of science recommend the use of history in school science programs to clarify different aspects of scientific inquiry, the human aspects of science, and the role that science has played in the development of various cultures.

HEALTH
 
By the end of Grade 8, students will:
1: Health Promotion and Disease Prevention

Students will comprehend concepts related to health promotion and disease prevention.

 
6: Setting Goals for Good Health

Students will demonstrate the ability to use goal-setting and decision-making skills to enhance health.

 
7: Health Advocacy

Students will demonstrate the ability to advocate for personal, family, and community health.

MATHEMATICS
 
In grades 6-8, all students should:
1. Numbers and Operations

Understand numbers, ways of representing numbers, relationships among numbers, and number systems.

Understand meanings of operations and how they relate to one another.

Compute fluently and make reasonable estimates.

 
2. Algebra

Understand patterns, relations, and functions.

Represent and analyze mathematical situations and structures using algebraic symbols.

Use mathematical models to represent and understand quantitative relationships.

Analyze change in various contexts.

Formulate questions that can be addressed with data and collect, organize, and display relevant data.

Select and use appropriate statistical methods to analyze data.

Develop and evaluate inferences and predictions that are based on data.

Understand and apply basic concepts of probability.

 
Instructional programs from pre-kindergarten through grade 12 should enable all students to:
1. Problem Solving

Build new mathematical knowledge through problem solving.

Solve problems that arise in mathematics and in other contexts.

Apply and adapt a variety of appropriate strategies to solve problems.

Monitor and reflect on the process of mathematical problem solving.

 
2. Reasoning and Proof

Recognize reasoning and proof as fundamental aspects of mathematics.

Make and investigate mathematical conjectures.

Develop and evaluate mathematical arguments and proofs.

Select and use various types of reasoning and methods of proof.

 
3. Communication

Organize and consolidate their mathematical thinking through communication.

Communicate their mathematical thinking coherently and clearly to peers, teachers, and others.

Analyze and evaluate the mathematical thinking and strategies of others.

Use the language of mathematics to express mathematical ideas precisely.

 
4. Connections

Recognize and use connections among mathematical ideas.

Understand how mathematical ideas interconnect and build on one another to produce a coherent whole.

Recognize and apply mathematics in contexts outside of mathematics.
