Expert Remixing

http://www.slnova.org/pwalpole/projects/83620/
I tried each of the remixing techniques described and the results still make sense because the slider represented the grass formation, although named differently, the coding associated with it defined it as grass. In the ecosystem the grass is the energy so as the program runs and you turn the grass formation to 0 using the slider, you have both a visual representation on the “game board” as well as the graph, illustrating how decline in grass results in a decrease of rabbits.

One area which I ran into trouble was when I created my slider, it was visible yet not working. I had forgotten to go back into the code and plug it in. Also, I had to assign a slider value larger than the value I had originally coded into the program for grass sprouts.

My remix isn’t running and I don’t know why?

http://www.slnova.org/cdhoff/projects/88791/ I added an agent with a camera. I also had the circles that the turtles were drawing become ovals.

I created this game where the user controls the blue square with the arrow keys (up, down, left and right). If you hit a purple square, you are sent back to the (0,0) to start again.

This a project I worked on with my partner as part of one of the modules. We included lots of cool features, including procedures, sliders and conditionals.

I added a procedure to add a sun that would be used to help increase evaporation. My problem now is that the program is running slowly. I will need to do some debugging.

Infected (red) agents have a camera
Recovery procedure, called with an additional conditional statement
Extreme wiggle added: 10 forward, 90 deg right, 90 deg left
Add slider for Recovery, # Healthy, and # Infected
Healthy become infected upon collision

http://www.slnova.org/MsWestfall/projects/89482/

Added copper nitrate breed to appear when silver nitrate collides with copper. It helps to make the solution look blue.

I added an extreme wiggle and made changes to the data box.

I was able to do many of the features, I added a slider, alternative breeds and added a graph.

This module simulates the spread of a disease. the disease transmits by 4 red turtle. Where healthy blue turtles collide with the red, they carry the disease, while when they collide with the yellow turtle (vaccinated) they won’t get infected.
I added a new agent called (New vaccine). When the red infected turtles collide with it they recover and turn into yellow. I also add the camera to the New Vaccine Agent, and add data box to count the red, blue, and yellow turtles. Additionally, I toggled off forever when the count of red equals zero.

I gave the camera to a silver nitrate molecule. the view was very agitated due to the amount of wiggle. I do not know if the camera is being handed off as molecules are reacting with the copper. creating the copper nitrate breeds with differing numbers of attached water molecules better illustrates the “blue-ing” of the solution as the reaction progresses. This is good for my advanced students to know.

Still trying to figure this out

Sorry, I was not able to do this activity. I am having a difficult time with StarLogo Nova.

http://www.slnova.org/hudmhond/projects/94026/
Worked on this. Not perfect, but was able to add a camera, collisions, different breeds etc.

http://www.slnova.org/hudmhond/projects/94027/
Again. not perfect. Contains sliders, cameras ect. collisions represent passing of germs etc.

Am I understanding the assignment correctly? We’re supposed to remix and discuss FOUR different models? I’ll be back once I’ve done one more. Here are three to start with.

Solutions Model: This is a (pretty significant) modification of the chemical reactions module. I’m trying to make it more about solutions and factors that affect dissolving, which are important ideas in 8th grade science in NYS. I added a couple of sliders as well as other widgets. If you click “probe perspective,” the probe agent takes the camera. (I’m not sure how to code it so that toggling off probe perspective will reset the camera… anyone figure this out?) The probe detects water and solute molecules within a certain radius, and graphs the results, allowing you to see how long it takes for the solute to move from the corner where it is introduced to the corner with the probe. I wrote procedures to make the molecules bounce when they collide, and called these procedures for both types of molecules. I am still working on code to add a sugar cube (rather than a “drop” of a solute) to make surface area experiments possible.

Epidemic with Vaccination: I don’t think this very accurately models the spread of disease, but I made a model that includes vaccinated turtles as well as sliders to control many different aspects of the model. I did not give the camera to the agents or create any new breeds, but I think I did all the other things. I was messing around with recovery and have it based on time, which creates some weird effects (a bunch of agents get well all at the same time). I plan to remix and improve this model to try other ways of handling recovery.

Prisoner’s Dilemma sandbox: I listened to an episode of Radiolab that talked about computer models of how altruism could have evolved. I was trying to see if I could make a similar model in StarLogo Nova. I think I have a lot of the basics working, but I’m not sure it’s a very accurate model. I don’t know if I understand the problem well enough to model it effectively. Again, I didn’t give the agents the camera (why would I?) but I did most of the other things. There are generous and selfish agents, and each has “energy” that allows it to reproduce. You can enter costs and benefits for generous and selfish strategies, and the various agents play these strategies when they collide, leading to changes in their frequency in the population. Due to problems with exponential growth crashing the program, I had to incorporate a count of agents and have it stop running when there are 500 agents.

First-Person Un-fun Game: I made this just to see what kind of “games” you can create, especially with a first person perspective. I was able to create mountains that are obstacles, enemies that appear and move around, and treasure to collect. I also created an interface for moving the player using the arrow keys. I think I used all the different aspects of code listed except procedures, but I have used procedures before and feel fairly confident I understand them.

Grim reaper & doctor are awesome ideas!

Rather than give a turtle a camera, I added another breed of camera to view my epidemic model. I did this to observe the reactions without being a part of the experiment.
