Other ideas

Some other ideas:
-A chemistry program to solve redox questions, or create polyatomic ions
-A program involving musical notes of an instrument ( to help teach or test skills )
-A program to help young children to differentiate colours or learn basic logic
-A 3-D engine that lets you create 3-D objects with a specific size and depth. Then allows you to add shapes together to build anything( such as an airplane or robot structure ) -> could also calculate area and volume
-A model of the laws of centripetal force or gravity of objects around another
-A fun way to inform how to convert decimals
-A program that informs students of turning points in history ( factors and effects from WW1 ) -> could be a game that follows through a timeline
-A program that either teaches, tests, or implements cryptography ( using hints to solve encrypted notes to solve the game )
-A program that simulates snowboarding
-A game to trade within a city and other cities to teach people how to get a feel for how to market.
-A game to help high school students and first year university students in learning the unit circle( being able to find cosine and sin values during critical angles ) -> we could implement this by having enemy objects enter the screen and having to enter the correct angle in radians to shoot missiles in order to save your vessel.
