Linked below are a selection of four of the “scratches” I developed in EDTECH 538. Although they are basic, they touch on the building blocks of all computer programming and computational thinking: Decomposition, Pattern Recognition, Abstraction, and Algorithms.

This scratch is a remix on the Line Follower Scratch from the text.
Project Link: Line Follower Project Code: I spent a lot of time on this scratch experimenting with different ways to achieve my goals. The first thing I wanted to do was to accurately track the lap time of the cat as they ran around the track. The second thing I wanted to do was figure out a way to have the cat stop if they fell off the track. Both of those things were implemented using color sensing but I am sure there is more than one way to skin a cat.

This is one of my first scratches and utilizes simple animation.
Project Link: Pacing Lion Project Code: This simple project utilizes animation and sounds to create an immersive scene. Click on the lion and see what happens!

This scratch utilizes variables.
Project Link: Pressure Under Water Project Code: This project was a little tricky because the supplied formula didn’t calculate pressure correctly becausedue to the fact that it did not correct for the absolute value of the y position. Once that was corrected for the fish correctly reported the pressure as they swam around.

This scratch calculates the resistance of multiple resistors in series or parallel.
Project Link: Resistor Calculator Project Code: This project was a lot of fun and also very annoying. It was fun because I was able to do something useful with scratch and enjoyed setting up a custom background while working with multiple variables. It was challenging becuase it is quite difficult to do complex calculations with the drag and drop interface of Scratch. I really wish we could just type things in!
