Why Milk Is Safe Teacher's Page
A Food Safety Unit for Grades 4-6, WebQuest Agricultural Series by Missouri Farm Bureau and Missouri State University 

 

INTRODUCTION

Milk is a safe and nutritious food source today. Throughout history milk has been a good food source for everyone. However it wasn’t until 1864 when Louis Pasteur developed a new technology called Pasteurization that milk became a safe food source for everyone. At one time Undulant fever was widespread throughout North America and other parts of the world. Many infants perished from drinking contaminated milk. Legislation in the United States requires that all milk products be pasteurized before human consumption. This law has made milk the safe product that it is today in the United States and Britain. Not every country requires pasteurization and Brucellosis and Undulant fever are prevalent throughout the rest of the world.

Your students may read other information concerning the lack of nutrients in pasteurized products. This could be another persuasive research project. However, for this project try to steer students away from this topic.

National Education Standards

 

Health Promotion and Disease Prevention

  • Students will analyze the influence of culture, media, technology, and others on health--Describe ways technology can influence personal health.

Language Arts (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 non print texts, artifacts, people) to communicate their discoveries in ways that suite their purpose and audience.

Language Arts (Applying Language Skills)

  • Students use spoken, written, and visual language to accomplish their own purposes (e.g., for learning, enjoyment, persuasion, and the exchange of information.

Science and Technology

  • Understanding about science and technology.

Science in Personal and Social Perspectives

  • Science and technology in local challenges.

Social Studies (History of Student's Own State or Region)

  • Understands the people, events, problems, and ideas that were significant in creating the history of their state or region.

Technology

  • Students use a variety of media and formats to communicate information and ideas effectively to multiple audiences.
  • 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.
  • Students use technology resources for solving problems and making informed decisions.
  • Students employ technology in the development of strategies for solving problems in the real world.

RESOURCES

There should be many print resources for students to access in school and public libraries. Most of the web sites covering Louis Pasteur are written at a higher reading level. Students may need materials that are at lower reading levels that are found in print materials.

COMMON CORE STANDARDS
