Cow Eyes Teacher's Page
A  WebQuest for Grades 6 - 8, WebQuest Agricultural Series by Missouri Farm Bureau and Missouri State University



INTRODUCTION

In this WebQuest, students explore two different websites about the eye. The websites have explanations and diagrams discussing the human eye. Related to the human eye, one website discusses the cow's eye and why we use it when talking about the human eye. The students will then answer questions about their understanding of the eye. After the students have basic knowledge they will be able to go through a virtual dissection of a cow's eye. If you would like to take the class through a real dissection the website provided in this WebQuest is a great tool to use on a projector or Smartboard to walk the students through the dissection. When the students have completed the dissection they are asked to draw and label an eye themselves. Before or after this WebQuest it might be beneficial to discuss or study different adaptations animals have developed over the years related to the eyes or compare and contrast different animal eyes and their uses/positioning.

Missouri Grade-Level Expectations


SCIENCE
Strand 3: Living Organisms


2. Living organisms carry out life processes in order to survive


C. Complex multicellular organisms have systems that interact to carry out life processes through physical and chemical means


Students will be able to explain how the eye reacts to light stimulus and how the muscle make the eyes move. ( grade 8 g)


F. Cellular activities and responses can maintain stability internally while external conditions are changing (homeostasis)


Students will be able to explain how the eye reacts to light stimulus and how the muscle make the eyes move. ( grade 8 a)


3. Genetic variation sorted by the natural selection process explains evidence of biological evolution


C. Natural selection is the process of sorting individuals based on their ability to survive and reproduction within their ecosystem


Students will be able to describe the adaption and purpose of the protective features of the eye. (grade 6 a and b)


Strand 7: Scientific Inquiry


1. Science understanding is developed through the use of science process skills, scientific knowledge, scientific investigation, reasoning, and critical thinking


C. Evidence is used to formulate explanations


Students will use technology to compare and contrast a cow's eye to a human's eye ( Grade 6,7,8 b)


E. The nature of science relies upon communication of results and justification of explanations


Students will be able to draw and label the parts of an eye (Grade 6,7,8 a)

HINTS FOR TEACHER USE:
Here is a link for students who ask for information about beef cattle or the cattle industry.


Students should find the answers to the worksheet questions from the eye link and how the eye links works link.
