How about: tension vs material of vibrating string; two strings of the same material but different tension have different pitch, two strings of different material but same tension have different sound, volume vs opening size (for wind instrument); two identical jugs with different water levels that you blow across the top of to make sound, two jugs of same volume but different opening size (might be a little trickier to find) tension vs area of drum heads; saran wrap over bowls for the cheap and easy way, real drums for the expensive way
What else can I help you with?
Which of the following is an important advantage of experiments over observational studies?
The main possible advantage is that in an experiment, it is possible to control some of the variables so that it is easier to measure the effect of key variables. In observational studies, no such control is possible.
What are some science experiments with variables?
A science project that has variables can be an experiment that aquires for variable change.
What is a separate experiment with no variables called?
For instance, in an experiment on plants, some plants may be subjected to variables - different fertilisers, soil, temperature, daylight, diseases, etc. While other plants would be kept separate as a control. The control plants would not be subjected to any variables or experiments. The control plants would be used to compare the growth and the effects on the plants that were subjected to the variables.
Do all experiments have a control?
All properly-designed experiments should have some sort of control.
What is the variable that is difficult to control?
There are many variables that can be difficult to control in various situations. Some common examples include human behavior, external factors like weather, and complex systems where multiple variables interact in unpredictable ways. It is important to identify and account for these variables when making decisions or conducting experiments to minimize their impact on outcomes.
Some variables that can change in an expeirement and discuss the inportance of a control group?
dependent variable & control variable
Did ancient philosophers perform controlled experiments?
No, ancient philosophers did not perform controlled experiments as we understand them today. Their methods typically involved observation, reasoning, and deduction rather than the systematic control of variables seen in modern scientific experiments.
What are some examples of a scientific variable?
Some examples of a scientific variable is Independent Variable Control Variables :)
Does qualitative research not control variables?
In qualitative research, researchers do not typically control variables in the same way as in quantitative research. Instead, they aim to explore and understand the complexities and nuances of a phenomenon without manipulating variables. The focus is on gaining in-depth insights and understanding the context in which the research is conducted.
What is the definition of a control variable?
Variables are simply names used to refer to some location in memory - a location that holds a value with which we are working. It may help to think of variables as a placeholder for a value. in system
What is experimental research method?
Experiments are studies involving intervention by the researcher beyond that required for measurement. the usual intervention is to manipulate some variable in a setting and observe how it effects the subject being studied.
Is ricky carmichael undefeatable?
No racer is undefeatable, there are too many variables that come into play in a race. No one can overcome all of those variables (some out of your control) every race.
