Maria and Elena want to answer the question of whether plants grow better with natural sunlight or artificial light by conducting an experiment.
The plants that receive no fertilizer in the plant experiment would be considered a control group. This group serves as a baseline for comparison against the plants that do receive fertilizer, helping to determine the effects of the fertilization on plant growth.
The control variable in this experiment would be the plants that do not receive any fertilizer. By comparing the growth of plants with fertilizer to those without, researchers can determine the effect of adding fertilizer on plant growth.
The higher plants percieve photoperiod by their leaves. The intensity and quality of light determine the duration of photoperiod for inducing flowering.
The respond variable in an experiment is the variable that changes as a result of manipulating the experimental variable. It is more commonly called the dependent variable. For example, in an experiment designed to determine whether fertilizer will increase the growth of plants, the respond variable would be the growth of the plants.
Why must controls (such as plants given water only) be used in the fertilizer experiment
there are unexpected results in a scientific lab because many times they are performing a new experiment, and though they gather information on what they are going to do, things might react in wierd ways. i did an experiment with plants and i watered them with bleach, water, milk, and coke, and the coke one grew to a ridiculous size.
An investigatory project is a planned experiment for the purposes of research. An investigatory project about plants would be to set up a controlled experiment to see which color of light that plants grow best in.
An experiment measuring the effect of temperature on the rate of chemical reactions or the growth of plants could utilize temperature as a measurement. By adjusting the temperature and observing changes in the reaction rate or plant growth, researchers can determine the impact of temperature on these processes.
There were three times as many tall plants as short plants.
Put one ivy plant in a cool place and another in a warm place, but give both the same amount of light and water.
