What else can I help you with?
What is the definition of manipulative variable?
A manipulated variable is also called an independent variable. It is the thing in an experiment you change or manipulate. For example, if i am doing an experiment to see how water affects the growth on plants, the amount of water is the manipulated variable.
What dependent variable is plant growth?
The dependent variable for plant growth experiments is typically plant height, biomass, or other measured characteristics such as leaf number, flower production, or root length. These variables are directly influenced by the independent variable being tested, such as different treatments, conditions, or factors.
Lisa is working on a science project and has to answer the question does Rogooti affect the speed of hair growth. Identify the control group and the dependent variable?
control group are the ones that are not being tested. dependent variable is the hair growth.
The effects of different colours of light on the growth of plants?
Different colors of light have varying effects on plant growth. Blue light promotes vegetative growth and is essential for photosynthesis. Red light stimulates flowering and fruit production. Green light is less effectively absorbed by plants, but can still contribute to growth. The ideal light spectrum for plants includes a combination of blue, red, and sometimes green wavelengths for optimal growth and development.
What is a controlled experiment?
A controlled experiment is one in which only one variable is changed at a time. A variable is something which can vary, or have different values. Scientific investigations always involve three types of variables: 1) The independent variable: this is the variable which you deliberately alter, so you will know its values before you start the experiment. For example, if you want to know how the amount of light a plant gets affects its growth, you must give aome plants different amounts of light. Since you need to choose the amounts, you will know the values of this variable before you start the experiment. 2) The dependentvariable:this is the variable you must measure to find out if it changes as a result of you changing the independent variable. Since you have to measure it to find out its values, you will not know the values (ie the results) before doing the experiment. In the plant example you wouls have to find some way of measuring plant growth in the different light conditions. 3) Controlvariables: these are any other variables which may affect the values of your dependent variable, so they need to be kept constant to make it a fair test. In our example, things like the temperature or the amount of water could also alter plant growth, so they would have to be kept constant. These variables are also called confounding variables. The basic principle is only alter one variable (the independent variable) at a time; keep everything else the same.

What does independent mean scientifictly?
In scientific terms, "independent" typically refers to a variable that is manipulated or controlled in an experiment to observe its effect on a dependent variable. The independent variable is not affected by other variables in the study, allowing researchers to establish cause-and-effect relationships. For example, in an experiment testing the effect of light on plant growth, the amount of light is the independent variable, while the growth of the plants is the dependent variable.
How would you write a dependent and independent variable for growth of crystals in a faster rate depending on temperature?
Dependent variable: growth of crystals Independent variable: temperature.
What is a variable that is used is a independent variable?
An independent variable is the variable of the experiment that the dependent variable depends on. For example, in an experiment testing the effects of soil quality on a plant's growth, the dependent variable would be the plant's growth and the independent variable would be the quality of the soil.
What is an independemt variable?
An independent variable is the variable in the experiment that affects the other variable. For example, in an experiment that tests the affect of the amount of fertilizer on plant growth, the amount of fertilizer is the independent variable and the plant growth is the dependent variable. This is because the plant growth DEPENDS on the amount of fertilizer.
How are independent and dependent variable related?
Independent variables can take values within a given boundary. The dependent variable will take values based on the independent variable and a given relationship at which the former can take its values.
What is a variable you change that changes the dependent variable?
The variable you change to affect the dependent variable is called the independent variable. For example, in an experiment measuring plant growth, the amount of sunlight the plants receive is the independent variable, while the growth of the plants (measured in height or biomass) is the dependent variable. By altering the independent variable, you can observe how it influences the dependent variable.
What is the difference between the independent and dependent variables in the experiment?
Dependent variable is your data, independent variable is what you are testing. Ex. Sunlight would be the independent variable and a plants growth would be the dependent variable.
What are the independent and dependent variables of how fertilizer affects plant growth?
The independent variable is the thing you are testing or the thing you control. The dependent variable is what you are measuring.
Things that may change during a experiment are called?
'Variables' are any factors that can be controlled, changed or measured. There are two types: the independent variable and the dependent variable. The independent variable is the condition that you change and the dependent variable is what you are observing. So if you are trying to measure the effect of water on plant growth the water would be the independent variable and the plant growth would be the dependent variable.
Dependent and independent variables in biology?
In biology, the dependent variable is the factor being measured or tested in an experiment, and its value depends on the independent variable. The independent variable is the factor that is manipulated or controlled by the researcher to observe its effect on the dependent variable. For example, if studying the effect of different fertilizer amounts (independent variable) on plant growth, the plant growth measurements would be the dependent variable.
What is the independent variable in an investigtion to find how light effects the growth of plants?
The independent variable in this investigation would be the amount of light received by the plants. This variable is controlled and manipulated by the researcher to determine its effect on plant growth.
What effect does the amount of fertilizer have on the growth of a plant what would be the independent variable?
Increasing the amount of fertilizer can lead to increased plant growth due to the availability of nutrients. The independent variable in this scenario would be the amount of fertilizer applied to the plant.
