Enzymes: Chew on This!

Carbohydrates in food are an important source of energy for the body. When you eat starch, it must be broken down into simple sugars before your body can use it for energy. In this Biograph Virtual Lab you will use a simulation to explore the breaking down of starch into sugar. The simulation will enable you to compare and contrast the conversion of starch to sugar both with and without enzymes. This will help you understand the role of enzymes in digestion.

Evolution Curriculum from BioGraph

Evolution is a change in genetic information in a population that is observed over many generations, due to the random chance survival and reproduction of particular individuals. In this BioGraph Virtual Lab, you will observe how a population of fish in a pond changes over time. By the end of this activity, you will understand how random factors (genetic drift) and non-random factors (natural selection) contribute to evolution.

Pond Ecosystem Biograph project

Ecosystems are made up of interacting, interdependent parts, which are always interacting with and changing each other. Healthy ecosystems are long-lasting. In a long-lasting ecosystem the number of plants and animals may increase and decrease over time, but there are always enough individuals to reproduce and establish the next generation. In this Biograph Virtual Lab your challenge is to build a model of a long-lasting, healthy pond ecosystem using Toolblox programming blocks.

Segregation Model

This model shows how a small preference for looking like one's neighbors can lead to a segregated society. The unit so far includes the model as a mystery model to be discussed and decoded by students, a partial piece of code with to use for decoding practice, a finished model, some background information, and a link to an on-line resource demonstrating these concepts. We are developing an off-line activity and other curriculum for this module -- stay tuned!

Simulación de un brote de Dengue

Este modelo simula la transmisión del virus del dengue en un barrio de cuatro manzanas durante 180 días. El vector del virus es el mosquito Aedes egyptii. La simulación muestra un gráfico con la evolución del brote (el cambio en la cantidad de personas sanas y de personas infectadas), otro gráfico con la evolución de la población de mosquitos y unos monitores que indican el estado de la población de mosquitos y cuántas personas fueron infectadas.

Dengue outbreak simulation

This model simulates the transmission of the dengue virus in a neighborhood of four blocks during 180 (one hundred and eighty) days. The vector of the virus is the mosquito Aedes egyptii. The simulation shows a chart of the evolution of the outbreak (the change in the number of healthy people and infected people), another graph with the evolution of the mosquito population and some monitors that indicate the state of the mosquito population and how many people were infected.

El Juego de la pesca (La Tragedia de los Comunes)

El Juego de la Pesca utiliza el concepto de Tragedia de los Comunes (Hardin, 1968) para trabajar sobre sustentabilidad. El jugador (pescador) tiene 10 días para atrapar tantos peces como pueda para alimentar a su familia. Cada día, el pescador puede elegir pescar uno, dos o tres peces, o no pescar ninguno. Hay otros dos pescadores que también tratan de capturar tantos peces como puedan. El lago en el que se pesca sólo puede soportar 20 peces (que es la capacidad de carga del lago).

Archived Material: CS in Science Module 1 (for StarLogo Nova 1.0)

Archived Material: Module 1 introduces basic concepts in modeling complex systems through hands-on activities and participatory simulations. A scaffolded series of highly-engaging design and build activities guide students through developing their first computer model in StarLogo Nova 1.0, a modeling and simulation environment developed at the Massachusetts Institute of Technology.

Spring Introductory Unit for Project GUTS after-school clubs

The Project GUTS after-school clubs were structured to have 10-12 week units in the Fall and Spring Semesters, with a 4-5 weeks Introduction to StarLogo Nova and computer science concepts, followed by a 5-6 week content unit. This is the curriculum page for the Spring Semester Unit introductory weeks. It assumes students had participated in the Project GUTS club during the Fall Semester, so might require building some background knowledge and skills for students new to StarLogo Nova.

Fall Introductory Unit for Project GUTS after-school clubs

The Project GUTS after-school clubs were structured to have 10-12 week units in the Fall and Spring Semesters, with a 4-6 weeks Introduction to StarLogo Nova and computer science concepts, followed by a 4-6 week content unit. This is the curriculum page for the Fall Semester Unit introductory weeks. It assumes students are new to Project GUTS and to StarLogo Nova. If you have repeating students, see the Resources Link to Other activities to Introduce Project GUTS for additional ideas.

Science of Friendship

Why do humans help some people and not others? This Project GUTS unit explores this question and allows students to test their own assumptions. Using methods and data from anthropology, sociology and psychology and computer modeling in NetLogo, students investigate the role of cooperation in human interactions—and how cooperation plays a role in global issues such as resource management, health equity and climate change.

Social Networks for StarLogo TNG

How are people connected? Humans are inherently social and have relationships far more complex than the random encounters often seen in agent-based modeling. These relationships can vary in strength and meaning – we see social networks that range from kinship networks, friendship networks to contact networks used in the study of epidemiology. The primary goal of this unit is to engage students in simple interactive activities to explore social network concepts and to model those concepts.

Geothermal Energy for StarLogo Nova

This unit was developed as a Project GUTS after-school club unit. Students learn about geology topics relating to hot springs with mineral deposits, as well as geothermal energy with hot water being heated underground and rising to the surface. Students decode a base model and add their own enhancements.

Climate change and agriculture for StarLogo Nova

Climate change is a significant topic today, and this unit examines some causes of climate change, discusses feedback loops that are important to climate change, analyzes related graphs and considers climate change in New Mexico as it relates to food security.

Opinion Dynamics for StarLogo Nova

This unit explores Opinion Dynamics as an aspect of human society that can be studied as a complex adaptive system. In modeling opinion formation and dynamics, agents representing humans can influence and be influenced by other agents locally through one-on-one interactions. It could be modified to model global influences (like media).
