For example, when experimenting with how fertilizer affects plant growth, the fertilizer is the independent variable because this is the variable that you change. ... In our experiment, our dependent variable would be plant growth since this is affected by the amount of fertilizer applied.
Does adding fertilizer affect the growth of a plant?
Fertilizers provide essential nutrients to plants in form of soluble salt compounds, and directly affect plant growth . ... Over- fertilization can lead to sudden plant growth with an insufficient root system to supply adequate water and nutrients to the plant.
Does adding fertilizer have an affect on the growth rate of a plant what is the dependent variable in this question?
If the amount of fertilizer applied to plants is increased, then plant growth (height) will increase . As the amount of fertilizer increases the plant growth increases.
How do the different chemicals in fertilizer affect plant growth What is the independent variable What is the dependent variable?
In the plant experiment, the independent variable could be fertilizer—some plants will get fertilizer, others will not. The scientists change the amount of the independent variable (the fertilizer) to observe the effects on the dependent variable (plant growth).
Does fertilizer help a plant grow taller identify the dependent independent and controlled variables?
Does nitrogen fertilizer affect plant height? If plants are given nitrogen fertilizer, then they will grow taller . Factors in an experiment that a scientist WANTS TO MEASURE and is changed by the independent variable.
How do you identify independent and dependent variables?
You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an experiment , you manipulate the independent variable and measure the outcome in the dependent variable.
How do you classify independent and dependent variables?
An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable . A dependent variable is the variable being tested and measured in a scientific experiment. The dependent variable is ‘dependent’ on the independent variable.
What kind of variable is the amount of soil and water?
For this science fair project, the independent variable is the type of soil used. The dependent variable is the amount of water retained in the soil.
What is the dependent variable in an experiment?
The dependent variable is the variable that is being measured or tested in an experiment . ... In a psychology experiment, researchers are looking at how changes in the independent variable cause changes in the dependent variable.
What fertilizer makes plants grow taller?
Nitrogen, phosphorus, and potassium are the big three in fertilizer formulations. Plants require these three macronutrients to grow large and lush. Nitrogen promotes the growth of the foliage, while phosphorus and potassium support the growth of strong roots, stems, flowers and fruits.
Does fertilizer make a plant grow taller controlled variable?
If the amount of fertilizer is increased, then plant growth will increase . ... If the amount of fertilizer applied to plants is increased, then plant growth (height) will increase. As the amount of fertilizer increases the plant growth increases.
Will a plant grow higher with more light dependent variable?
Sunlight is related to plant growth. If the amount of sunlight is increased , then plant growth will increase. The hypothesis that plant growth increases as the amount of sunlight increases was supported by the data.
Is water a controlled variable?
For example, if we want to measure how much water flow increases when we open a faucet, it is important to make sure that the water pressure (the controlled variable) is held constant . That’s because both the water pressure and the opening of a faucet have an impact on how much water flows.
What is meant by dependent and independent variables?
In analytical health research there are generally two types of variables. Independent variables are what we expect will influence dependent variables . A Dependent variable is what happens as a result of the independent variable.
Which is dependent variable?
The dependent variable is the variable that is being measured or tested in an experiment . ... The dependent variable is dubbed dependent because it is thought to depend in some way on the variations of the independent variable.
