experimental
Trying something new to test an idea or method.
Experimental means trying something new to see what happens, testing an idea that hasn't been proven yet, or using methods that break from the usual way of doing things.
Scientists conduct experimental treatments when they test new medicines that might work better than existing ones. An experimental aircraft uses new technology that engineers haven't fully tested in flight. When you try an experimental approach to your science fair project, you're attempting something different from the standard methods, hoping to discover something interesting.
Artists create experimental music or paintings when they explore unusual techniques or combinations. A chef might offer an experimental menu featuring unexpected flavor pairings. These experiments might succeed brilliantly or fail completely, but that's the point: you learn either way.
Something experimental always carries some uncertainty and risk. That's what makes it exciting. When the Wright brothers built their experimental flying machine, many people thought it would never work. When a student takes an experimental approach to solving a math problem, they might discover a clever shortcut, or they might need to try a different path. The willingness to experiment, to test new ideas even when success isn't guaranteed, is how people make discoveries and push boundaries.
