Why is it important to test only one variable at a time during a science investigation?
If you test only one variable then you know that the difference in the experimental and control setup is that one independent variable. If you test more than one you will not know which one made the difference.
What are the basic steps in conducting science investigation?
The scientific method is a way to ask and answer scientific questions by making observations and doing experiments.The steps of the scientific method are to: Ask a QuestionDo Background ResearchConstruct a HypothesisTest Your Hypothesis by Doing an ExperimentAnalyze Your Data and Draw a ConclusionCommunicate Your ResultsIt is important for your experiment to be a fair test. A "fair test" occurs when you change only one factor (variable) and keep all other conditions the same
How many variables are changed in an investigation?
Only one variable at a time . after one time has passed you can use more ..
Why do scientist share information?
It is important for scientists to communicate to others not only the results of the investigation, but also the methods by which the investigation was done.
Why is a control needed in a scientific method?
Because In a scientific method there has to be a independent,controll,and dependent variable. A control group has to be in a scientific method cause ther is only one needed.
Why is only variable changed in an investigation?
You only change one variable in an investigation because if you change more than one you won't know which change affected the data.

If you test only one variable then you know that the difference in the experimental and control setup is that one independent variable. If you test more than one you will not know which one made the difference.
Why do you use scientific investigation?
Scientific investigation is the best, and maybe only way to find the truth in something without the results being skewed by personal opinions.
What is the best number of variables for a scientific investigation?
In an experiment containing a number of possible variables only one of these should be altered in each individual experiment. Otherwise it is not possible to determine which variable is responsible for a particular change.

What is responding valuable?
Do you mean "responding variable"? In a scientific investigation, you try to change only one thing to see what happens. The thing you change is the manipulated variable (also called the independent variable). The result of this change is the responding variable (also called the dependent variable). For example, what if you measure the temperature of a beaker of water, then put it in the refrigerator for 24 hours, then measure again. The change in the temperature from the room to the fridge is the manipulated variable (you controlled it). Any change in the water temperature is the responding variable. It responded to the change you made.

What is bias in a scientific investigation?
Bias in a scientific investigation usually comes in the form of wanting a particular result. This can skew with the process, doing things that an objective experiment would never do, such as only choose certain results as valid.
Why do scientist share information?
It is important for scientists to communicate to others not only the results of the investigation, but also the methods by which the investigation was done.
Is scientific investigation expected to be certain?
Absolutely not. Hypothesis testing will never support a hypothesis, only fail to reject it.
Why is a control needed in a scientific method?
Because In a scientific method there has to be a independent,controll,and dependent variable. A control group has to be in a scientific method cause ther is only one needed.
What are the variables in a scientific experiment?
There are 3 different variable. The independent variable is what you will be changing in the experiment and there should only be one. The dependent variable is what you will be measuring or observing. The controlled variable is what you will be keeping the same and there can be more than one. There is no limit on how many controlled variables you can have.
