Earth Science Challenge #2


Hi. I chose the first question. Honestly, it is because I broke my wrist and it makes it hard to work at the computer.

I changed the location of pumps and the depths of the pumps. I also have plants.


I did challenge number 2. It was not difficult at all.

  1. I chose to make a shallower pump simply because I needed an ego boost and since I am familiar with the coordinate plane, x- and y-values make sense to me.
  3. Changing the pump was easy. (However, my issue of no data being collected in the data box for pump #3 is still an issue.)
  4. Any ideas on how to get the box to record data?

I chose to to the easier challenge because I was able to figure out the x and y coordinates and I was able to do this part easily.


I chose to add a toxin to the water source and view how the increase in toxin would affect the evaporation of water. With added time this model could be adjusted to illustrate how the addition of water could help dilute a small source of toxins in a water source.
I had an issue with saving my models - so I provided to links to the two models I was modifying for this project.


I was able to make the pump shorter. I learned that the heading of 270 is very important in this module. When I changed in to 180, my pump was horizontal. A very good lesson for my students to discover while coding.


Looks like I got ahead of myself:


For this challenge I chose the easy - to make a deeper or shallow pump. I made a shallow pump but the size of the actual pumping component is the same. Saw a big difference in the data collected. Struggling a smidge with the coding because of other craziness happening at school. Not as much time to devout to it as I need. Here’s my link:


I chose to change the color of the terrain to see how that effects the water cycle.
I changed the color and movement but then I realized I had to add that color to the ground water movement, otherwise it would just sit there.


I found this relatively straightforward, especially after the debugging tutorials on saturday.

  1. I chose to make the pump more shallow, again because I am not familiar with this module.
  3. No struggle, actually, the code was pretty easy to read.
  4. I’m good!


I created a layer that is labeled pebbles. It works ok but seems to change every time I work on it. I’m still working on changing the colors and getting the water to move correctly.


I chose the easy challenge for the simple reason students would chose it too. And just like them I regret the easymode and wish I chose the toughest one. There’s hardly any struggle here - the programming is straightforward and even by simple experimentation you can quickly figure out which setting was for the pump_depth.


Once again not topic I teach so chose to make a shallow pump
Changed wrong value then quickly saw my mistake

#35 chose the first one

earth science challenge 2 (easy)
changed pump depth and position


I chose the easy challenge, because of time & interest.

At first, I forgot to adjust the “repeat ___ times” to match my new y-coordinate setting for the shallow pump.

No help needed at the moment.


Hello this is Mary Helen from Houston.

I chose to answer the first challenge question because this water pump model is the one I studied during the PD.

Here is the URL link :

What I struggled with the most was understanding how changing the x coordinate would change the placement of the pump. And how changing the x coordinate into the negative position would change the placement of the pump.

I still need help understanding the true placement of the pump. I do not think that I am fully understanding.


I choose the intermediate challenge. I find it interesting and was able to figure the code. I tried to attempt the hard challenge but SLNOVA kept crashing.

Wasn’t hard after I understood the repeat function.
