In the first video segment, we analyze the population dynamics for a test-tube of cells that affect each others' likelihoods of replication when they collide. The particular example we use is a prisoner's dilemma, which has the almost paradoxical property that survival of the relatively most fit leads overall fitness to decrease. In the second video segment, we suggest that the population dynamics from the first segment can be related to an analysis that uses payoff matrices found in traditional game theory.

The Future of Food is an introductory-level science course that emphasizes the challenges facing food systems in the 21st century, and issues of sustainability for agriculture and other food production activities, as well as the challenges posed by food insecurity and modern diets to human health and well-being. Topics covered include introduction to the coupled-system perspective, historical development of food systems, socioeconomic aspects of the food system, interaction of the food system with the Earth's environment including soil, water, biota and climate, and the future of the food system considering potential changes such as in climate, urbanization, and demography.

In a quiet forest in central Florida, a mysterious pond filled with warm clear water hides a secret at the bottom. In this video, Jonathan explores the pond to find a spring which leads into a cave. As Jonathan travels underground, he meets unexpected marine life in the dark depths and learns how water travels through an aquifer from the underground world to the surface. Please see the accompanying study guide for educational objectives and discussion points.

The Greater Yellowstone Science Learning Center is a portal to information about the natural and cultural resources of Yellowstone and Grand Teton (including John D. Rockefeller, Jr. Memorial Parkway) national parks and Bighorn Canyon National Recreation Area. By reporting on what has been learned from research and monitoring in these parks, we hope to increase public awareness of new findings and encourage studies that will help guide park management decisions. The National Park Service has set up Research Learning Centers as public-private partnerships that promote the sharing of scientific knowledge about the parks.

The student will be able to define and describe herbicide formulation types.  Students will understand basics and importance of a jar test.  Students will be able to follow tank mixing order instructions

In this module your main task is to plan and carry out a set of activities with selected households in the community to help them gain a good understanding of their current and possible future use of natural resources in their area.

This guide is intended to support you in adapting the State of Innovation’s “Our Communities after COVID-19” Challenge case into a lesson plan to implement with your students. It includes background information on the case, problem solving questions for students to work on, and suggested activities to use with your students. It also explains how you can get support during the Challenge, including helping your students connect with industry leaders throughout the Challenge.

What does forestry even mean? Well, what it means has changed a lot over time. As the public’s perception of forestry has changed so has the profession. The 1944 and 1958 Society of American Foresters (SAF) Dictionary of Forestry, defined forestry as “the scientific management of forests for the continuous production of goods and services.” Compare that to the most recent 2018 SAF Dictionary of Forestry which defines forestry as:
“the profession embracing the science, art and practice of creating, managing using, and conserving forests and associated resources for human benefit and in a sustainable manner to meet desired goals, needs and values -note the broad field of forestry consists of those biological , quantitative, managerial, and social sciences that are applied to forest management and conservation; it includes specialized fields such as agroforestry, urban forestry, industrial forestry, nonindustrial forestry, and wilderness and recreation forestry.”

As you can read, the profession has changed over time and now encompasses a variety of disciplines all adapted to meet desired goals, needs and values. This text is not comprehensive of all the disciplines but an introduction to them. Additionally, as this is an Introduction to Forestry, the set of readings was selected to be engaging and create interest and not be an end. It is hoped that this sampling of the topics will generate additional interest in the profession and the broad field of forestry and encourage you to investigate further.

The educational material consists of an introduction to the pesticide problematic together with five themes that illustrate different aspects of the problematic. Below you find video-clips from Bolivia that visualizes and concretizes the theme described in the fact sheet (downloadable PDF), including study questions that encourage the students to reflect upon the theme presented in the educative videos as well as in the fact sheet. Furthermore each fact sheet contains a reference list1 and grey boxes in the text with suggestions for further reading on the themes. 

Have a grow tower? Have a green house? Have a garden? Use the Let’s Get Growing curriculum!

This curriculum is an out-of-school curriculum designed to explore food, science, engineering, technology, and innovation in plant production.

The goals of the curriculum are to take students on a journey to understand food scalability and for students to begin growing enough food to supplement a school lunch, sell at a farmer’s market, or provide to students and their families.

This project relates to Ecology Standards and Literacy Goals. I have combined several different levels of this project so that the activity can be adapted for different levels. I have used the activity primarily with High School students and introductory-level biology with college/university students. The content could also be adapted for middle and elementary students. I would choose a book for the students on these lower levels but that is also an option at the higher levels as well.

Even experienced divers rarely get to see the Mandarinfish, a colorful reef fish that is so shy, it only comes out of hiding for a half-hour a day. In this video, Jonathan travels to the south Pacific to film spawning Mandarinfish and witnesses an incredible secret ritual. Please see the accompanying study guide for educational objectives and discussion points.

List of countries with their annual methane emissions. The data are from 2005. The data are given in total annual emissions, thus must be compared with economic activity, geographic and most importantly, population data to be relevant.
