Why should you make a table to record data for an experiment?
Because the table is where you will get most of your marks in a practical exam.
What is the role of responding variable in a controlled experiment?
it is basically asking what the definition of responding variable is and the book says, The variable that changes because of the manipulated variable is the responding variable.
What are conditions in a experiment that are the same for all groups?
Conditions in an experiment that are the same for all groups are known as controlled variables. These include factors such as temperature, time, equipment, and environmental conditions that could influence the outcome of the experiment. By keeping these conditions constant, researchers can ensure that any observed effects are due to the independent variable being tested, rather than external influences. This helps to enhance the reliability and validity of the experiment's results.
What form do you write your hypothesis in an experiment?
In an experiment, a hypothesis is typically written as a clear and concise statement that predicts the relationship between two variables. It often follows an "If... then..." format, where the "if" part states the condition or independent variable, and the "then" part predicts the outcome or dependent variable. For example, "If the temperature of water increases, then the rate of dissolving sugar will increase." This structure helps to establish a testable prediction for the experiment.
What are two main variables in an experiment?
The two main variables in an experiment are the independent variable and the dependent variable. The independent variable is the factor that is manipulated or changed by the researcher to observe its effect. In contrast, the dependent variable is the outcome or response that is measured to assess the impact of the independent variable. Together, these variables help establish cause-and-effect relationships within the experiment.
When you make a conclusions about an experiment what do you need to consider?
the variables and the facts so you don't make any mistakes about the conclusion.
Why do you need to do experiment?
To prove or disprove a theory. If you didn't perform experiments you wouldn't have the evidence to move forward in your scientific knowledge. Try an experiment 4 times to get a reliable average result.
What is controlled unclassified information?
Unclassified information requiring safeguarding and dissemination controls, pursuant to and consistent with applicable laws, regulations, and government-wide policies.
What can scientists do if the results to an experiment do not support a hypothesis?
Throw away that hypothesis because it is wrong. Form a new, different hypothesis and design and undertake experiments to test that one.
What is an observation and measurements recorded during an experiment?
The observations and measurements recorded during an experiment are called data. It is important to keep accurate data in order to understand the results of the experiment.
What is it called when scientist test their experiments more then once to prevent errors?
trial and error
What role does independent and dependent variable play in controlled experiments?
The independent variable in an controlled experiment is what you are changing (for example, amount of water or sunlight a plant gets). The dependent variable changes because of the independent variable. Its the outcome of the independent variable.
In an experiment what is the experimental data compared to?
In an experiment there is one thing that it is compared with experimental data. This is when the end results.The experiment data is compared to one thing. It is compared to the end results.
Why do people need to do science experiments?
Why did Newton have to drop an apple? Same concept. The experiment must be tested to see if it works. Not experimenting can lead to devastating consequences.
What were the results of the potato battery experiment?
It depens on how you set it up, and what your trying to for, for example the potato clock can easily run for weeks or months on end but only puts out 1-2 volts
What do you understand with consistency and accuracy from experiment?
The accuracy of a measurement is the degree to which it approaches the true value.
The true value of some feature is the value to which a large number of reputable measurements, made by competent experimenters, tends.
Consistency or more commonly, repeatability, is the ability of the experimenter and their equipment to produce a consistent result.
At a formal level, organizations such as standard institutes, ISO, ASTM and so on will have published their definitions of these important concepts.
The independent variable is what you are changing in the experiment to get varied results. The dependent variable is the result of what you have changed. So the dependent variable depends on the independent variable. For example, if you are experimenting with the effect of water on height of a plant, the different amounts of water that you give the plant is the independent variable. The height of the plant that you measure as the result of the water is the dependent variable.
How do you convert plastic to oil?
haha.i am engaged in the indusry that convert <a href=www.doinggroup.com/index.php?u=show-285.html> convert plastic to crude oil</a>for fuel.hrough hydrous pyrolysis. Under pressure and heat, long chain polymers of hydrogen, oxygen, and carbon decompose into short-chain petroleum hydrocarbons with a maximum length of around 18 carbons.then the waste tire or waste plastic will be converted into crude.it is really amazing.
Why did Obama teleport nude to mars?
because nothing dead would go through the teleportal....only the living person
What variable that a scientist changes when conducting an experiment is called the what variable?
The variable that a scientist changes in an experiment is called the independent variable. This is the variable that the scientist manipulates to observe its effect on the dependent variable.
