The purpose of an experiment is to establish cause and effect relationship.
In science an experiment has to do with the process in which there is the establishment of a cause and effect relationship between the variables in the experiment. Thus the purpose of an experiment is to establish cause and effect relationship.
The correct steps in the experiment are;
Predict what happens when lead nitrate reacts with potassium iodide.
Measure 100 ml distilled water into each of two beakers.
Measure out 0.3 grams each of the solids, lead nitrate and potassium iodide.
Dissolve each solid in a separate beaker of water.
Pour both solutions into one container and slowly stir.
Watch mixture change from clear to a yellow solid and record observations.
Write a science report detailing results and conclusions.
Create a presentation and share findings with peers.
