I have picked this scratch project to modify:
Under the hood is quite complex, but I don’t think it’s too hard for students to analyse and then manipulate. I would ask students to look inside the script to find out how the program works. I would scaffold potential changes to the students. Changing the scripts around sprite movement is one option. Another might be changing the costumes completely to frame fresh questions altogether. They might even just change the octopus sprite.
However students approach this, there is enough variance to keep all students challenged.
