Natural Selection Programming

A lesson for middle school science that uses a variation of the rabbits and grass program to explore concepts of natural selection.

Image of sugar moving into bloodstream from MIT Biograph materials

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).

An Example of CT in the Workplace

This is an example of how a computer modeler uses various aspect of computational thinking while designing, creating and using a computer model as a tool to think with.

Progress Monitors for CS in Science Modules (coding activities)

Progress Monitors are meant to be guides for students, giving goals for the model but not providing specific coding instructions.

Module 3 Lesson 3 - Adding a Predator

In this lesson, students will modify the Rabbits and Grass model by adding a predator, a Mountain Lion, to answer a new question: “Does adding a top predator increase or decrease the stability of an ecosystem?” In the second activity, students will design and run experiments to see if adding a predator has an impact on the ecosystem. This activity will reinforce the concepts of energy flow through ecosystems and the often unexpected results of interactions in complex adaptive systems.

Module 3 Lesson 4 - Create Your Own Ecosystem Model

In this lesson, students will design their own ecosystems projects consisting of a question, experimental design and model. In the first activity, students will learn about the computational science cycle and use it to scope their project. This leads to a second activity where they start designing and implementing their model.

Module 3 Lesson 5 - Designing and Running an Experiment and Sharing Your Findings

In this lesson, students will complete their ecosystems models and then design and run experiments using their models as experimental test beds. As an extension, students can prepare a presentation on their model, experimental design and findings.

Decode NYC Models

In the NSF-funded DecodeNYC program at the American Museum of Natural History, middle school students use the agent-based game and simulation programming environment StarLogo Nova to use, modify, decode, and create scientific models to test different strategies for fighting Lyme disease and answer questions about their urban ecosystem.

DECODE NYC Virtual Lesson Plan - MODIFYING A MODEL: OMNIVOROUS FOXES

This remote lesson serves as an opportunity for students to modify the code of an agent-based model to reflect the complexity of real-world food webs. Students will evaluate theeffectiveness of the modifications based on their understanding of population dynamics.

Gene Regulation and Protein Synthesis

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.
