What equipment qould be needed to perform this experiment?
What equipment was needed for this experiment
What safety precaution should you take when performing an experiment that involves electricity?
Always perform the experiment under adult supervision.
What happens when scientist have to redo an experiment?
Depending on the size/importance of the experiment, they can either simply repeat as normal or if needed gather more resources for the experiments. Scientists always perform experiments at least three times, to make sure nothing is abnormal in an experiment.
Can iron wire conduct heat?
This an experiment you may perform simply for yourself. Hold a steel needle so that its tip is in the flame of a candle.
Describe an experiment you could perform to determinethe average speed of a toy car rolling down an incline?
roll a car down a hill
How do you identify a variable in an experiment?
In an experiment, usually one item will cause something else to vary in an observable manner and sometimes predictable way.A variable will be recognized as any factor, trait, or condition of the experiment that exists in varying amounts or types. There are independent variables, dependent variables, and controlled variables.An independent variable is one that is changed in an experiment. In order to perform a fair and subjective test one should consider only one independent variable during their experiment. As changes are made in the quantities of our independent variable, changes should be apparent that make observations different from other quantities of the independent variable.The focus of these observations is on the depenedent variable to see how it responds to the change made to the independent variable quantities. The new value of the dependent variable is caused by and depends on the value of the independent variable and is what we know as cause and effect.Not to be forgotten, we have the controlled variable which is a quantity that is maintained at a constant in the experiment so as to eliminate any confusion with cause and effect observations.
What do you need to perform a controlled experiment?
An independent and a dependent variable. A hypothesis. And lab coat, a white one.
What is an inependent variable?
If I am not mistaken, the question should be "What is an independent variable?" The answer is this: An independent variable is a variable whose results are independent of all the other variables measured in the data sets/experiment. For an exaggerated example, if one were to perform Van de Graff Machine experiment where the values measured are Static Energy, Time, and The Number of Stars Present in the Sky, one would be likely to find the Statics Energy and Time would have a direct relationship whereas The Number of Stars Present in the Sky would have no relationship to Static Energy or Time.
What variable should you already know before you perform a experiment?
A manipulated variable. (Apex)
Are controls always necessary in an experiment?
Yes 99.99% of the time,controls are very necessasry.If you are performing an experiment testing some variable, say (X) , you need to perform a control where everything is the same as the experiment conditions including your (X) variable your testing in the experiment. Therefore, the only difference between your control and your experiment is the variable your testing.Since the variable in your control is kept constant, you can compare the result so the experiment (where the variable was varied) and your control (where the variable was kept constant).Since all other factors in both the control and experiment were the same, you can compare your results
When a chemist perform an experiment the quantity is being tested is the?
control
How do hypothesis help in doing some experiment?
Because it will perform a test of how two variables might be related. This is when you are doing a real experiment.
The four main parts of an experiment?
First and foremost you must specify the hypothesis you are testing by the experiment. So you will have a testable null and alternate hypothesis. Next you will detail the resources and procedures used to generate the data needed by the tests specified by the hypothesis. Then using the described resources and procedures you will generate and record the data specified by the first two components. Next you will perform the analytic tests on those data, and record those results relative to the specifications made by your hypotheses. Following that you will write a summary of your results test and conclude whether your null hypothesis was shown to be not false based on you experimental results. Finally, you will write recommendations for further action and/or experiments based on your own experiment.
Describe a constant in an experiment?
In any experiment there will be many things which we need to keep the same. For example, if we are finding out how long a chemical reaction is lasting for, we need to make sure that the ingredients and the same amounts of them are used throughout the experiment. Things we need to keep the same are called constants.
How do psychologists use the scientific method to study behavior and mental processes?
Psychologists use the scientific method to form research questions, gather data through experiments or observations, analyze the data, and draw conclusions. This systematic approach allows them to test hypotheses about behavior and mental processes in a controlled and replicable manner. By following the scientific method, psychologists can make reliable and evidence-based conclusions about human behavior.
Did democritus perform a experiment?
only when he wanted to perform an experiment.
Why aren't experiments always accurate?
It depends on what kind of experiment you are performing, an experiment can never be entirely accurate but the more times you perform them, the more of an accurate result you will get.Answer:An experiment in a school lab is more correctly a demonstration. The errors are caused by unfamiliarity with the equipment, methods, or recording of results.In a research laboratory an experiment is reaching into new areas. The potential variables are not all known. Lack of the control of these variables can cause error in the results.
