  1. Which challenge question did you chose, and why?
  2. URL for public link.
  3. What did you struggle with most?
  4. Is there anything else you still need help with?


I decided to make the pump more shallow. I struggle with the position numbers, however using the correlation chart really helped make it easier. I had to do several trials and error until I got it to move up.

  1. I chose the easiest challenge because I am not teaching this subject material.
  3. I did not struggle with anything.
  4. I do not need any additional help. Thank you.


I chose to create asphalt. I chose this one to start planning how I will present the information to the students. I struggled mostly due to computer compatibility and not able to run and test the code written. It was very challenging to create a code and not being able to test it.


I chose this challenge because it took the least amount of time. I am not teaching this in class.

No struggles.


I chose to add an additional pump because I had already started the process in the in person class. I still need help on adding another procedure. In the class, I just typed it in the box next to the purple procedure code but that’s not working now.


After adding a second pump , I decided to set the second pump slightly deeper than the first. This was pretty straight forward. I just needed to adjust the y-value.


If you put your project in the ‘public gallery’ on SLNova, I can try to take a look at the code and see if there is anything that I can help with.

I changed one of the pumps so it’s more shallow. I chose this to make sure I know how to give it a new location. Makes me more comfortable with the ideas before I give it to the students to use and modify


This one wasn’t as bad as the first one for me. I, admittedly, chose the easier assignment because I was feeling a little beat up by my first challenge where my pump just wouldn’t work. This time, it was easy to move and it worked just fine. It was easy to see how the shallower pump near the deeper pumps was just inefficient by comparison.


I chose easy because I am not teaching this module.
It was easier than the first challenge.


In creating my third pump I altered the x and y coordinates to make the pump more shallow than my other two pumps.

  1. I chose the medium challenge because I wanted to explore how to move layers and create interactions in Spaceland.
  3. When I wanted to change the size or location of the layer, the spheres would move through the layer.
  4. I don’t fully understand what the meaning of size is in the traits drawer. I have coded some interactions that only work if above a certain size. Also, when the location is changed some interactions will not work, I would like to know why that happens.


Hi Kenneth- I wasn’t able to look at your project (probably not in your public gallery). However, I have a suspicion that you used a ‘stamp’ block in the new well your created whereas the original one had a ‘stamp grid.’ The ‘stamp’ block is sensitive to the size difference but the ‘stamp grid’ does not change with the size trait, it is always one patch in size.
I’m not sure about the location affecting interactions so I’d have to see the project to understand that more.
Be in touch if you have any questions-

Paige, I added the project to my public gallery. I did switch to the ‘stamp grid’ for my makeAsphalt procedure and it did not interact with the water droplets.


What I’m seeing is that the water is indeed interacting with the gray asphalt as you coded it but perhaps you were expecting a different behavior. When water hits the asphalt it changes to a gray color (in the ‘groundwater’ procedure). Also, when it hits the asphalt it’s movement stops and it slowly evaporates (in the ‘evaporate’ procedure). According to your code, only water that hits the asphalt will evaporate, all other water drops continue through the cycle.

If you want to make different changes, let me know.

I wanted the asphalt layer to line up with the stamped ground but, in trying to do that, the water would no longer react with the asphalt layer. When I tried the stamp grid command, the layer did not interact at all.


I chose the easy challenge.
I was able to do this challenge without too much difficulty because I understood how to change the depth of the pump.
I think I don’t really understand what the procedure “pump” is actually doing.
I think I just need to review the module.


I chose to create asphalt which is medium level.
I chose this one to start planning how I will present the information to the students. Also exploring how to move layers and create interactions in Spaceland.

When I wanted to change the size or location of the layer, the spheres would move through the layer.
When the location is changed some interactions will not work, I am not sure why that happens…

  1. I again chose the easiest challenge, partially because I’m still thinking through how and whether or not to use this model at all, and partially because whenever things get too complicated, star logo nova seems to stop working (i.e., pages won’t load) so it gets frustrating to try and tackle more complicated tasks
  3. I’m going to try a few more variations - I’d like to measure how much water the shallow pump is taking in v. the deeper pumps using widgets.
  4. I need to refresh my memory on how to make my program count this type of information, but for the moment, I am fine and don’t think I need additional help. I may try out some of the more advanced challenges or try working more with another module.
