Natural Selection Prey and Predator

This post includes a link to a model that can be used with the OpenSciEd Bacteria Food Hunt Unit net logo simulation.

Modeling molecules is solids, liquids, and gases

Posted May 12, 2021 by mbuhl

This model simulates intermolecular forces and lets people change the temperature using a slider. At high temperatures, you can see the molecules fly around as a gas, with occasional collisions. With lower temperatures they condense to a liquid, and even lower they freeze to a solid.

Middle School Dissolving Salt Chemistry Module options

Posted August 4, 2017 by mmarkham

This lesson was developed to be used with two stand alone models developed by GUTS as alternatives to the Chemistry Module 4. This is aimed at middle school students. This pairs a hands on lab activity with the CS models to explore the strengths and weaknesses of CS models of physical changes at an introduction to chemistry level. Students decode the models and make changes including adding and testing variables.

Modeling Change

Posted July 3, 2017 by sgibbs

This contributed curriculum physics unit introduces and builds models to explore concepts of independent and dependent change, constant and variable x and y change, gravity, and projectile motion. Each lesson contains detailed instructions on how to build each model, and links to base models and completed projects. Modeling Change Lesson 1 is also uploaded as an independent resource (since it can serve as an alternative introduction to StarLogo Nova).

Alternative Intro to StarLogo Nova - Modeling Change Lesson 1

Posted July 3, 2017 by sgibbs

The first part of the Modeling Change Unit can be used as a fun stand-alone programming activity for students unfamiliar with StarLogo Nova. It guides students to build a model that use keyboard controls to change the two-dimensional location of agents (in section 1a) and change other traits including the third dimension (z), shape, color, and heading (in section 1b).

Sugar Transport Activity

Posted April 17, 2017 by turtle

Have you ever drank a can of soda and suddenly felt more energetic? In this Biograph Virtual Lab, you will use a simulation to explore how the glucose molecules from the soda move from the lumen of your small intestine, across the membranes of your epithelial cells, and into your bloodstream. (Ultimately, the glucose in your bloodstream will move into your body’s cells).

Gene Regulation and Protein Synthesis

Posted April 17, 2017 by turtle

Every cell in your body has a full set of genes, or ‘recipes,’ to build many different kinds of proteins (including enzymes). What causes a gene to go from its normal ‘turned off’ state (when it IS NOT building proteins) to its ‘turned on’ state (when it IS building proteins)?  To answer this question, we will zoom in and take a closer look at a gene and its environment to see how and why a specific protein is made.  

Enzymes: Chew on This!

Posted April 17, 2017 by turtle

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

Posted April 17, 2017 by turtle

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

Posted April 12, 2017 by turtle

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.
