What are the scientific variables and what do they mean?
In an experiment, the independent variable is the variable that is manipulated, for example plant fertilizer. The dependent variable is what is observed and measured as a result of the independent variable, for example plant height. Controlled variables are factors that are kept constant for the entire experiment, such as temperature and moisture, so that the observed results are due only to the independent variable. So in an experiment measuring the effect of fertilizer on plant growth, the independent variable would be the fertilizer, the independent variable would be the height measured at specific intervals, and the controlled variable of temperature and moisture would be kept the same for both groups.
Why is a controlled experiment important to science?
A controlled experiment means that you try to keep all the variables that are involved in the experiment under control apart from the Dependent and the Independent variables to make sure that any results obtained from the experiment have been affected by the independent variable and not some other extraneous variable. It also ensures that the experiment would have high validity. That is, if the experiment has really measured what it was supposed to measure.
What are the 3 scientific variables?
The three scientific variables are independent variables, dependent variables, and controlled variables. The independent variable is the variable that is manipulated or changed by the researcher. The dependent variable is the variable that is measured or observed in response to the changes in the independent variable. Controlled variables are the factors that are kept constant to ensure that they do not influence the relationship between the independent and dependent variables.
What unit is specific heat measured in?
In SI, specific heat capacity is measured in joules per kilogram kelvin.
The aim of an experiment should be in the form of a what?
An experiment should be designed to answer a specific question.

What is the operational definition ot the dependent variable in this experiment?
The operational definition of the dependent variable is the specific way in which it will be measured or observed in the experiment. It is typically the outcome or response that is being studied or affected by the independent variable.
What is a precise description of how the variables in a study will be observed and measured?
The variables in a study will be observed and measured using specific tools, such as surveys, questionnaires, or instruments designed for data collection. Researchers will follow a structured procedure to ensure consistency and reliability in data collection. Data may be collected through direct observation, self-reporting by participants, or other means depending on the nature of the variables being studied.
What is the operational definition of the dependent variable in this experiment?
The operational definition of the dependent variable in an experiment specifies how the variable will be measured or observed. It defines the specific outcome or response that is being assessed as a result of manipulating the independent variable.
What is a variable in a controlled experiment?
In a controlled experiment, the control variable is the one specific thing that is kept constant to measure the change of the other variables. Those variables are the parameters that are being tested.
In which step of the scientific method would a scientist determine the specific variables of the experiment?
Observation.
How can I effectively write an experiment procedure?
To effectively write an experiment procedure, start by clearly stating the purpose of the experiment. Then, outline the materials needed, the steps to be followed, and the variables to be measured. Be specific, use clear language, and include any safety precautions. Finally, review and revise the procedure to ensure it is detailed and easy to follow.
What is The measurable part of the experiment?
The measurable part of an experiment is the aspect that can be quantitatively observed, recorded, and analyzed. This typically involves collecting data, taking measurements, or recording specific outcomes based on the variables being studied in the experiment. These measurable results are crucial for drawing conclusions and making inferences based on the experiment's findings.
How many variables do you change at one time during an experiment?
To ensure valid results, it is best to only change one variable at a time during an experiment. This allows you to understand the specific impact of that variable on the outcome. Changing multiple variables simultaneously can make it difficult to determine which factor is responsible for any observed changes.
How many variables do you test within one experiment?
Generally speaking, you only want to test a single variable within one experiment so when a change occurs you know what caused it. If you change multiple variables at once it is harder to attribute the change to a single cause.
Why is a controlled experiment important to science?
A controlled experiment means that you try to keep all the variables that are involved in the experiment under control apart from the Dependent and the Independent variables to make sure that any results obtained from the experiment have been affected by the independent variable and not some other extraneous variable. It also ensures that the experiment would have high validity. That is, if the experiment has really measured what it was supposed to measure.
How do you measures variability?
Variables are measured differently depending on what you are measuring. Liquids are measured in mL and distance is measured in metres.There are lots of ways to measure different things so you should be more specific.
