experimental techniques

Experimental techniques are methods scientists use to investigate and understand the natural world. They involve designing experiments to test hypotheses, collect data, and analyze results. Techniques can include measuring substances with precise instruments, observing changes under specific conditions, or manipulating variables to see their effects. For example, microscopes help visualize tiny objects, while chromatography separates mixtures. These methods ensure that experiments are accurate, reproducible, and scientifically valid, allowing researchers to draw reliable conclusions and expand our knowledge across various fields such as physics, chemistry, biology, and medicine.
