This activity is an introduction to population sampling techniques. Students' will identify weaknesses and strengths of a variety of techniques and determine the best applications of the various methods identified.

In this deterministic cellular automata model, interactions between neighboring automata are described using a prisoner's dilemma. Limiting dispersal of seeds of annual plants can permit heterogeneous co-existence, whereas thorough mixing instead allows one subpopulation to dominate quickly.

Why are some countries rich and others poor? This fundamental question has been on the mind of economists since Adam Smith wrote "The Wealth of Nations" in 1776. This is a full course that covers all the major issues and developments in the field of development economics. Unlike typical college courses, we will take you to the frontier of the discipline, covering recent research as well as more established material. This course is non-technical and is accessible to a beginner. If you pass the final exam, you will earn our "Development Economics" certificate on your profile.

This diabetes self-management case is being utilized in the dietetic internship program courses at Iowa State University: FSHN 554, 555, & 556 and was designed to increase student confidence in suggesting appropriate recommendations for the medication, blood sugar, and diet management aspects for someone with Type 2 diabetes. As a distance education program, the dietetic internship faculty have created various simulations and case studies for students to gain practice and confidence in providing appropriate patient care.
1. Complete the diabetes self-management case: https://rise.articulate.com/share/wycLssQVOP7tsDhoY2o-KQUWacAChpqH
2. Compare your responses to the expert feedback.

This presentation focus on which role nutrition plays in developing diabetes and how obesity affects diabetes development. Obesity and weight gain dramatically increase the risk of developing type 2 diabetes. But it’s not only the total calorie intake and the BMI that counts, so does the distribution between fat, protein and carbohydrates, in other words the composition of nutritions. In continuation of this it will be discussed how a restricting intake of carbohydrates might be the way to reduce or even eliminate the use of medication in diabetes treatments.

Narrator: Richard Steed.

This presentation address how being overweight and obese is considered one of the strongest predictors, regarding the development of type 2 diabetes. Almost 85 % of people living with diabetes type 2, are either overweight or obese. This is an important aspect, because globally we have a lot of overweight people, in fact in 2014, one in three adults was overweight and one in eight was obese. But why do the numbers keep growing and what’s causing this epidemic growth of obesity?

Narrator: Richard Steed.

This presentation talks about who is at risk of developing diabetes and how diabetes will affect the future generations. You will be introduced to how the global amount of people diagnosed with diabetes, according to the WHO and the IDF, will increase from just over 400 million to 600 million by 2030.

Narrator: Richard Steed.

The overarching goal of this exercise is for students to explore the early anthropogenic hypothesis, which claims that early agriculture had a substantial impact on greenhouse gases and global climate thousands of years ago (Ruddiman, 2003). Students compare changes in greenhouse gas concentrations that occurred thousands of years ago to more recent changes that occurred over hundreds of years. Students also relate changes in greenhouse gas concentrations to warming. The exercise is completed over a 1.5- to 2-week period as the class covers a chapter on climate change.

This video segment from Greater Boston examines whether environmental toxins may be to blame for a rare skin disease.

Students will use MyFitnessPal or another teacher-approved website to record their food and drink consumption for 10 days. Then students will complete a reflection focused on analyzing if students met their recommended daily nutrition goals and nutrients.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Nutrient-poor diets can increase the risk of neurodegenerative diseases such as Alzheimer’s, and diets poor in fiber are widespread, especially in industrialized nations. However, whether fiber deficiency—which alters the gut microbiota—impairs cognition through the gut–brain axis remains unclear. To find out, researchers recently analyzed mice fed a fiber-deficient diet for 15 weeks. Compared to normal mice, the fiber-deficient mice exhibited cognitive impairment and were unable to complete typical activities like nest organization. In addition, the synapses in the brain area regulating cognitive function were damaged, and neuroinflammation occurred. Immune cells called microglia (indicated by Iba1) engulfed synapses (indicated by PSD-95) in the fiber-deficient mice. Furthermore, the fiber-deficient mice exhibited gut microbiota disruption that was associated with, and possibly responsible for, the cognitive deficits..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

In this first lesson, students will discover how foods from the garden fit into a healthy diet. Students will explore different types of gardens, and form their garden rules and garden teams. They will learn the function of different plant parts, and classify plants according to what part is edible. Finally, students will be introduced to the MyPlate icon, a reminder to eat
from the five food groups, and discover how they can eat smart to play hard with fruits and vegetables!

Eleven inquiry-based lessons that engage 5th and 6th graders in growing, harvesting, tasting, and learning about fruits and vegetables. The curriculum includes reproducible student handouts, 35 copies of the Dig In! At Home parent booklet (parent booklet also available separately in Spanish), and a set of 6 Dig In! posters.

After visiting the school garden to identify and pick vegetables ready for harvest, students create a poster model to show the journey food takes through their digestive system. Students then compare and contrast the digestive process of a plant (garden vegetable) with that of an animal (human). Students will further identify and compare nutritious and innutritious (junk) foods for both humans and plants.

Interactive worksheet to practice the different parts of the systems involved in the Nutrition process. This worksheet can be used as an assignment after previously teaching the concepts through a presentation like the one suggested: https://view.genial.ly/5e7ca1377ef4b40d8d18d808/presentation-human-body-explanation

An Introduction to Soil Science

Short Description:
Written entirely by members of the Canadian Society of Soil Science, "Digging into Canadian Soils: An Introduction to Soil Science" provides an introduction to the core disciplines of soil science, and introduces the concepts and vocabulary needed by students just beginning their soil science journey. The textbook provides supplementary materials that are specific to regions in Canada, or may be of specific interest beyond what might be considered introductory soil science material. Importantly, the textbook also is intended to introduce students to the Canadian System of Soil Classification by providing examples from across the length and breadth of the world’s second largest country, and to the Canadian Society of Soil Science, whose members share a common passion for soil science and are keen to share and instill this passion with students across Canada.

Long Description:
Written, reviewed and edited by members of the Canadian Society of Soil Science, Digging into Canadian Soils: An Introduction to Soil Science provides an introduction to the core disciplines of soil science (pedology, soil biology and microbiology, physics, chemistry, fertility and nutrient cycling, and management), and introduces the concepts and vocabulary needed by students just beginning their soil science journey. The textbook is appropriate for use in a number of disciplines, including environmental and agricultural sciences, as well as related geology, geography and natural resources engineering disciplines.

Chapters within the textbook are presented in three sections according to the content and level of the complexity. The first section of the book, Digging In, introduces core disciplines in a series of chapters written by authors whose research expertise informs the chapter content. Supplementary materials that are specific to regions in Canada are presented in chapters within a second section, Digging Across Canada. The third section, Digging Deeper, provides in-depth overview of some topics beyond what is considered core soil science disciplinary material, and may be appropriate for upper level soil science or related discipline courses. The textbook includes an extensive glossary that is accessible via in-text links. Importantly, the textbook is intended also to introduce students to the Canadian System of Soil Classification by providing examples from across the length and breadth of the world’s second largest country, and to the Canadian Society of Soil Science, whose members share a common passion for soil science and are keen to share and instill this passion with students across Canada.
