What else can I help you with?
Is the independent variable the thing you change?
Yes The independent variable is also known as the manipulated variable. In an experiment where you need to test different objects, the independent variable would be the different objects.
What a testable question about the natural world that contains an independent variable and dependent variable?
That the surface tension of water varies with the water's temperature. In this case, temperature would be the independent variable and surface tension would be the independent variable.
What is the independent variable in alka seltzer?
The independent variable in an experiment involving Alka-Seltzer could be the amount of Alka-Seltzer used, the temperature of the water it's dissolved in, or the surface area of the Alka-Seltzer tablet. It is the variable that is deliberately changed or manipulated by the experimenter to observe its effect on the dependent variable.
What is the independent variable in the question how does the angle of light affect the temperature of the surface?
The independent variable in this question is the angle of light. It is the variable that is being changed or manipulated to observe its effect on the temperature of the surface.
What is the dependant independent and constant in the question time it takes to run a mile depends on the persons running speed?
In this scenario, the independent variable is the person's running speed, as it can be manipulated to observe its effect on the dependent variable. The dependent variable is the time it takes to run a mile, as it changes in response to the running speed. There may also be constant variables, such as the distance of one mile and environmental conditions (e.g., track surface, weather) that remain unchanged during the experiment.
Can there be more than one independent variables in a experiment?
In general yes. But it really depends on the experiment. If you want to know if it hurts to punch a wall, you don't need an independent variable (unless you want to compare the magnitudes of the pain). But for school experiments, most of the time, if not all of the time. Yes.
Why is it important in an ideal simple experiment to change only one variable from trial to trial?
If you change more than one independent variable and your dependent variable changes, you wont know which independent variable caused the change to occur. eg - If I change something will I run 100m faster. So your dependent variable is the time it takes to run 100m If you have 2 independent variables (shoes and surface run on), you might run first in tennis shoes on grass then in football boots on tarmac. Now say you ran faster the second time, you wont know if you ran faster because you were wearing boots, or if you ran faster because it was on tarmac or because of some boots-tarmac combination. That's why you only change one independent variable. Aim: Does changing X effect Y (only change X; only measure Y)

How do you design an adsorption experiment of colour on adsorbent?
put the beads in bacterial liquid culture for some day for adsorption. check the coating by conducting SEM surface topology.
Which variables affect solubility?
Heat will increase solubility of solids but not for gases, pressure will increase solubility of gases, surface area of solids increases solubility, agitation increases solubility. __________________________________________________________ Well it depends on what experiment you are doing but i say it would be between the independent variable and the dependent variable.
What was the controlled variable domino dash lab?
In the Controlled Variable Domino Dash lab, the controlled variables included factors such as the height from which the dominoes were released, the type and size of the dominoes used, the surface on which they were placed, and the spacing between the dominoes. These variables were kept constant to ensure that any changes in the outcome could be attributed solely to the independent variable being tested, such as the angle of the initial domino or the force applied. By controlling these factors, the experiment aimed to produce reliable and consistent results.
What is the independed variable when building a raft powered by surface tension?
The independent variable when building a raft powered by surface tension would be the raft design or materials used. By changing these factors, you can observe how they affect the ability of the raft to float and move on the water surface due to surface tension.
