Debate Figures

Discipline:

Graphs of 140 years of global temperature anomalies and sea level.

In this class activity, students will participate in a debate on climate change policy. They will apply their understanding of the scientific evidence for climate change in order to propose specific policies for dealing with the changing climate. This document is a student handout containing supporting figures that can be used for the debate; an instructor guide is provided in an accompanying document.

Biodiversity Final Exam

Discipline:
Resource type:

This exam consists of five multipart questions related to the biodiversity materials presented in Frontiers of Science. The document provided here contains the questions and associated figures, while the answers are provided in a separate document. Each question requires students to apply their understanding of both content and the scientific habits of mind learned in the biodiversity unit. (Note: We provide the exam questions and answers to guide instructors in designing their own assessments. Since this Web site is freely accessible to anyone, including students, we recommend revising these questions to suit your own course content.)

Biodiversity Seminar 3

Discipline:
Resource type:

Lake Victoria

This document serves as a teaching guide for the third of three seminars in a unit on biodiversity. This seminar focuses on invasive species in order to underscore the difficulties of managing and restoring ecosystems and the potential damage of intended or unintended manipulation. As explained in the corresponding lecture, biodiversity theory can explain the causes and consequences of biodiversity loss and provides recommendations for mediating the sixth global extinction event and thus ensuring the availability of ecosystem services, the health of the biosphere, and the quality of human life. The guide includes an overview, reading list, and step-by-step seminar plan, including suggested discussion questions, activities, and reference to assignments. Related seminar activities and assignment questions are provided in accompanying files.

Biodiversity Seminar 1b

Discipline:
Resource type:

Depletion of fish stocks.

This teaching guide provides ideas for an alternative or additional seminar to include in a unit on biodiversity. The topics included in this guide are related to species decline in aquatic ecosystems. The guide contains an overview of the seminar, a reading list, and a step-by-step seminar plan, including suggested discussion questions, activities, and references to associated assignments. The related assignment questions are provided in an accompanying file.

Invasive Species and Population Dynamics

Discipline:

Time series plot of balsam fir growth and moose population in Isle Royal National Park 1959–2003.

In this assignment, students will consider the effects of invasive species on ecosystems, and look at population dynamics in predator-prey relationships. In examining data from previous studies, students will apply their understanding of graphical displays of data and of statistical concepts (mean, standard deviation, variance, correlation, significance) to interpret research findings. This document serves as a student handout; an answer key is provided in an accompanying document.

Invasive Species and Population Dynamics

Discipline:

Time series plot of wolf and moose populations in Isle Royal National Park 1959–2003.

In this assignment, students will consider the effects of invasive species on ecosystems and look at population dynamics in predator-prey relationships. In examining data from previous studies, students will apply their understanding of graphical displays of data and of statistical concepts (mean, standard deviation, variance, correlation, significance) to interpret research findings. This document serves as an answer key; a student handout is provided in an accompanying document.

Wombats and Bees

Discipline:
Resource type:

Butterfly, bird, and plant declines.

This assignment requires students to consider data related to diversity in local animal populations. Students will apply their understanding of samples, populations, and statistics to data from several different published studies of biodiversity. This document serves as a student handout; an answer key is provided in an accompanying document.

Wombats and Bees

Discipline:
Resource type:

Fruit-set effect sizes of pollen-supplementation experiments, North America.

This assignment requires students to consider data related to diversity in local animal populations. Students will apply their understanding of samples, populations, and statistics to data from several different published studies of biodiversity. This document serves as an answer key; a student handout is provided in an accompanying document.

Population Ecology

Discipline:
Resource type:

Expected decline without TEDS.

In this assignment, students will consider models for managing populations of sea turtles and fish. For the first question, students will apply their understanding of statistical concepts (means, standard deviations, t tests, hypothesis testing) to the results of a model simulation and use their analysis to make a policy recommendation about turtle conservation. In the second question, students will calculate and compare the survival rates resulting from two strategies of fish population management. This document serves as a student handout; an answer key is provided in an accompanying document.
