对高中生来说，了解人类环境健康是一个困难的问题，科学调查的过程也是如此。本模块提供了一个框架，通过基于查询的方法，使用假设驱动的一组实验，借鉴了现实生活中的关注，环境暴露于铅（Pb2+??），解决这两个问题。学生将学习科学家如何使用模式生物来理解基本的生物学概念，以及这些模型如何与人类和环境健康相关。学生观察Pb2+如何改变鱼的行为。由于涉及到许多层次的生物组织，本模块适用于普通和高级生物课程的多个单元。从已知的Pb2+毒性开始，学生提出关于它如何影响行为的可测试假设，将这些知识应用于人类群体，并确定“下一个实验”。
ABSTRACT Understanding human environmental health is difficult for high school students, as is the process of scientific investigation. This module provides a framework to address both concerns through an inquiry-based approach using a hypothesisdriven set of experiments that draws upon a real-life concern, environmental exposures to lead (Pb2+???). Students learn how scientists use model organisms to understand basic biological concepts, and how these models relate to human and environmental health. Students observe how Pb2+ alters fish behaviors. Because many levels of biological organization are involved, this module has application for multiple units within general and advanced biology classes. Beginning with what is known about Pb2+ toxicity, students develop testable hypotheses about how it may affect behavior, apply this knowledge to human populations, and identify the “next experiment.”
