When planning your investigation identify all the variables that need to be controlled which are variable that might affect the results such as. The independent variable sometimes known as the manipulated variable is the variable whose change isnt affected by any other variable in the experiment.
Type of soil.
Independent variable for plant growth. There is one dependent variable which is plant growth but the question needs to identify how this variable will be changed. Effect of Variables on Plant Growth Authors. The temperature of the environment.
The independent variable is the amount of nutrients added to the crop field. It is one of the important climatic parameters that influence global vegetation. In our example for instance the growth rate of the plants.
____ salt _____ Dependent variable. These amounts have been selected due to their range in water over the course of one day and because of the small size of each individual. Tap water distilled water ocean water lake water etc.
Nothing else in the experiment. You want all the plants to have the same growing conditions. Type of plant.
A variable is part of an experiment that can change such as the amount of light temperature humidity or plant growth as well as the direction of plant growth. Dormancy can be defined as the physiological condition of a viable seed that prevents germination. There is one independent variable which is water but the question needs to be more specific.
The independent variable is what you change and the dependent variable is what happens because of the change. For example in an experiment about the effect of nutrients on crop growth. What the scientist changes or what changes on its own.
Type of light. Type of container used etc. The dependent variable is the biomass of the crops at harvest time.
Salt in soil may affect plant growth. The type of plant the time given for the plants to grow the amount of sunlight received and the amount of soil or nutrient solution received. The only way to get reliable results from this experiment is to make sure that all the other variables stay the same or are controlled.
Yes there can be more than one dependent variable. It can be measured visually as whether the seeds have germinated or not. What is the temperature of the water.
Plant growth may be affected by the color of the light. Independent Variable The independent variable for this experiment will be the amount of water given to the plant every 12 hours once at 7am and again at 7pm. If you were measuring the growth rate of plants under full sunlight for 8 hours a day versus plants that only have 4 hours of full sunlight per day the amount of time per day of full sunlight would be the independent variable - the variable that you control.
The amount that the plants grow depends on the amount of sun they get. There will be one set of seeds that is given 1ml another 5ml the third 10ml the fourth 20ml and the last 50ml. In an experiment an independent variable is a variable that changes either on its own or you purposely change it.
Plant growth or seed germination. For example total dry weight is more accurate than height as a measurement of plant growth but in the case of a tree experiment height might be more practical. Where you compare effect of the presence and the absence of the independent variable on the dependent variable In hypothesis of amounts.
Where you compare the effect of different amounts of the independent. There are many variables. _____ if the salt containment goes up then the growth of the plant will go down because the chemicals in the salt will kill the plants _____ _____ _____ 3.
This article throws light upon the five major factors influencing the nature of plant growth. In an experiment you manipulate the independent variable and measure the outcome in the dependent variable. A quantitative way to measure the dependent variable would be to.
The growth rate of the plants would be a dependent variable. The amount of water each plant receives. What is being studiedmeasured.
_____ plant growth _____ Formal hypothesis. The length of the plants roots and stems after a certain amount of time. What is the source or kind of water.
Either the scientist has to change the independent variable herself or it changes on its own. Height Of the plants Unit of Measure. It determines the distribution of the biological forms over the earths surface and length of growing period.
If a plant receives sunlight then it will grow taller than a plant that does not receive sunlight. The independent variable fertilizer treatment can also be defined in numerous ways that will help specify experimental questions. Hypothesis In hypothesis of presenceAbsence.
Whether the plant is grown in soil or hydroponically. If a plant receives more sunlight then it will grow taller. Amount of soil.
