Animal Science Bundle 1
Tracking the Spread of Infectious Diseases (#906): Contagious diseases can spread very quickly through a population. If an infected individual mingles with healthy individuals, random contact can cause many more to become infected. This activity simulates the transmission of a contagious disease and the steps epidemiologists take to try to determine its source and limit its spread. Two scenarios are provided, one for an infection spreading among humans and another among livestock. If desired, the kit materials can also be used to simulate different ìtrackableî spreading event scenarios such as an invasive species or an outbreak of food poisoning. This activity also introduces the concept of exponential growth.
Natural Selection and Antibiotic Resistant Bacteria (#904S): Students use a model to explore the cause-and-effect relationship between inappropriate use of antibiotics and the phenomenon of the evolution of antibiotic resistance. This model is suitable when investigating bacterial infections in humans and other organisms, including livestock and pets. As they model the effects of antibiotics on the population of disease-causing bacteria they use mathematical representations to support their analysis of patterns and trends in the results. They then develop explanations for how and why the population of bacteria is changing and demonstrate that it is critical to remember to administer each dose on time and to complete the entire prescribed course of antibiotics.
Bacteria Study (#160): Students conduct the classic Leeuwenhoek bacteria experiment in this individualized, self-paced kit. Paralleling methods performed over 300 years ago, students observe and identify bacteria using a microscope.

Scientific Concepts
•Disease is a breakdown in structures or functions of an organism. Some diseases are the result of intrinsic failures of the system. Others are the result of damage by infection by other organisms.
•Design and conduct a scientific investigation.
•Develop descriptions, explanations, predictions, and models using evidence.
•Think critically and logically to make the relationships between evidence and explanations.
•Recognize and analyze alternative explanations and predictions.
•Scientific explanations emphasize evidence, have logically consistent arguments, and use scientific principles, models, and theories.
•Safe living involves the development and use of safety precautions and the recognition of risk in personal decisions.
•Individuals can use a systematic approach to thinking critically about risks and benefits.
•Important personal and social decisions are made based on perceptions of benefits and risks.
•Culture bacteria.
•Prepare bacterial smears and stain them using Gram stain.
•Observe and identify bacteria.
