Investigators use laboratory experiments to exercise maximum control over the factors they are interested in. This method allows researchers to manipulate variables directly to study their effects in a controlled environment.

Killing weeds with boiling water can be effective as a method of weed control. The hot water can damage the weed's cells and roots, causing them to die. However, this method may not be as effective for larger or deep-rooted weeds, and it can also harm nearby plants if not applied carefully.
Meteorologists carefully analyze various weather factors such as temperature, humidity, wind patterns, and air pressure to predict the path and intensity of a storm. By closely monitoring the storm's starting point, direction, and speed, scientists can make more accurate forecasts of its potential impact on a specific area.
Experimental Method
The control of the scientific method is the results compared to this part of the experiment.
A control is needed in the scientific method to establish a baseline for comparison. It helps ensure that any changes observed in the experiment are directly due to the independent variable, allowing researchers to rule out other influencing factors. This enhances the reliability and validity of the experiment's results.

The effectiveness of a fogger pest control method in eliminating pests in indoor spaces can vary. Foggers can be effective in reaching pests in hard-to-reach areas, but may not completely eliminate all pests. It is important to follow instructions carefully and use in conjunction with other pest control methods for best results.
