Black plastic sheeting, bulldozing, controlled burns, manual or mechanical removal, mulches, roto-tilling, salt, vinegar, weed-eaters and weed-killers are ways to rid stone-covered gardens of plants and weeds. A small stone garden can be controlled for weeds by removing the rocks temporarily -- to clear-cut the ground, with bulldozers or roto-tillers, or to solarize vegetation by putting down permanently weighted down black plastic sheeting. The other options do not require removing the rocks but working around them to eliminate plants and weeds.
In a homemade lava lamp experiment, the independent variable is the factor that is being manipulated or changed by the researcher, such as the type or amount of ingredients used in the lava lamp. The dependent variable is the factor that is being measured or observed as a result of the changes made to the independent variable, such as the rate of bubbling or movement of the colored liquid in the lava lamp. Other controlled variables, such as room temperature, container size, and stirring technique, should also be considered to ensure the validity of the experiment.
