What describes the materials and equipment needed and procedures tobfollow in an experiment?

The materials and equipment needed for an experiment are typically outlined in a materials list, which includes all necessary items such as chemicals, tools, and measurement devices. Procedures describe the step-by-step instructions for conducting the experiment, detailing how to prepare, execute, and analyze results while ensuring safety protocols are followed. Together, these components ensure that the experiment can be replicated and yield reliable results. Clear documentation of these elements is crucial for scientific integrity and reproducibility.
