What is an experiment name?
The name of a science experiment is generally a short phrase summarizing what you did in an experiment. For instance, if I tested how temperature affects bean germination, my title might be "The Effects of Temperature on Bean Germination."

In the effects of x-rays on seed germination experiment what would be the variable being tested?
the result
How many variables are generally tested in an experiment?
The trick to designing a good experiment is to figure out a way for it to test the effects of only one variable, and to avoid any effects of others.
What's a negative control?
A negative control is a control group in an experiment where the variables are not expected to have an effect. It helps researchers to determine if any observed effects are due to the treatment being tested or other factors.
How do you know that a variable is really a control variable and what is the property of control variables?
If you're performing an experiment in which your result depends on multiple variables, but you're just interested in how one of those variables effects the result, you would generally keep all of the other variables constant in order to negate their effects. Those variables that you're keeping constant are called control variables, and you would choose them based on the experiment. For example, say you wanted to determine how changes in resistance effect a circuit's current. Well, current is dependent on not only resistance, but voltage as well, and since you're only interested in the effects of resistance, you would make voltage the control variable, keeping it constant.
Kevin recorded the effects of violent video games on antisocial behavior. Which of these is a response variable?
Variables of interest in an experiment (those that are measured or observed) are called response or dependent variables. Other variables in the experiment that affect the response and can be set or measured by the experimenter are called predictor, explanatory, or independent variables. Antisocial behavior
What dose controlled experiment mean?
this is an experiment that only one varible is manipulated at a time
What are controlling variables?
== ==
Effects of cucumis myriocarpus crude extracts on germination of water melon?
inhibited germination and growth
Effects of overcrowding during seed germination?
sometimes it encourages germination and sometimes it inhibits it. its hard to tell when.
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.
