This project is a follow-up to the Science Buddies project Explore Optical Illusions: Build an Infinity Mirror, which shows you how to build a basic infinity mirror using light emitting diodes (LEDs) and arts and crafts materials. What if you wanted to build an infinity mirror that could change colors, like the one in Figure 1? Figure 1. A color-changing infinity mirror. You can do this by using special RGB (red, green, and blue) LEDs. Just like the pixels… Read more

Imagine that you have a list of names of all the people in your class. Someone asks you to put them in alphabetical order. How would you go about doing it? Would you first go through the entire list and look for all the "A" names? Then go through it again and look for all the "B" names, and so on? Do you think going through the list over and over again for each letter would be inefficient? What if you had hundreds, thousands, or even millions of names? How would you ever alphabetize them… Read more

Does it just do basic arithmetic (addition, subtraction, multiplication, and division)? Can it do other mathematical functions, like square roots or exponents? Can you use parenthesis? Does it have a backspace button? That is a lot to consider for a seemingly very simple device or program! For a computer science project, can you write your own… Read more
