Another gem from the prolific creator 😉

I wish I knew about this when I learned chemistry!! It’s PERFECT for the visual learners.

Not for the iPad

This isn’t formatted correctly for the iPad. I have no idea if the science is portrayed directly. I’d give any kid who wants to try to create an app to help other students lots of credit. Keep working on it!

Great job!

Back in the 80’s, I wrote many computer programs to demonstrate principles of trigonometry and calculus and those programs won state high school science and math fairs. Your gas laws app reminds me of the spirit I had when writing my programs.

To further help others learning to code, I hope you will consider posting your code online (e.g., on GitHub) and add a link from a future version to that code.

Regardless of what path you take in college and your career, I encourage you to continue coding. It’s a skill that helps improve your problem solving abilities and can ultimately provide an income stream.
