One of my favorite reasons for working in Scratch is that I can see, very clearly, how my code works. I see immediate results and can iterate based on what I see. That makes following my “what if…?” ideas easy and usually leads to even more learning and discovery. Designing activities that encourage these explorations helps students further their understanding of computational thinking concepts and practices.

Here is a fun Scratch art project I created recently that teachers could use with their students, whether they are meeting in person or remotely. It’s a project that could be used in an art class, or in any class to let students explore some of the blocks in Scratch prior to doing a bigger project. I have written this as a blog post for teachers to read and follow, but it would be easy to adapt for students.

  1. Have the change value be higher in the clone code than in the original sprite code. Then reverse the values. Pay attention to how the color seems to move along the trail.
  2. Have the numbers be close to one another. Then have the numbers be far apart from one another.
  3. Make one of the values higher than 50.
  1. Try changing the number while the code is running.Try adding a negative sign to the number while the code is running.
  2. Try adding a random number block that will select a number between 0 and 5.
  3. Try changing the random number range to -5 and 5.
