Experimentation is the process of trying things out to discover what works, what doesn't, and why. When scientists perform experiments in a laboratory, they're testing their ideas by carefully changing one thing at a time and observing what happens. When you experiment with a new recipe by adding extra cinnamon or substituting honey for sugar, you're learning through trial and error.

Experimentation means being willing to take risks and possibly fail. Thomas Edison conducted thousands of experiments before inventing a practical light bulb. Each failed attempt taught him something valuable about what wouldn't work. Artists experiment with different painting techniques, musicians experiment with new sounds, and engineers experiment with various designs before finding the best solution.

The word suggests a curious, playful mindset where you explore your own ideas. When a teacher encourages experimentation during a science project, she wants you to ask “what if?” questions and test your own ideas, developing them through hands-on discovery.

Real experimentation requires careful observation. You need to notice what changes when you try something new. A baker experimenting with cookie recipes keeps notes about what happened each time. This combination of curiosity, courage to try new things, and attention to results is what experimentation is all about.
