What is the first step in the static electricity experiment?

The first step in a typical static electricity experiment often involves preparing the materials to observe the effects of static charge. Placing salt and pepper on a black piece of paper creates a surface where the effects of static electricity can be easily visualized. The contrasting colors of salt and pepper against the black background make it easier to see how they react to static charge when introduced, such as attracting them towards a charged object.

Starting with this step ensures that the settings are ready for the demonstration of static electricity. The other options, while relevant to the experiment, either involve preparing the materials without directly setting them up for observation (such as rubbing the spoon or filling a bowl with water) or are tasks that come later in the experiment sequence (like placing the spoon in the salt shaker). Thus, preparing the visual component first aligns nicely with clear experimental practices.
