The amount of yeast in the elephant toothpaste experiment affects the rate and volume of foam produced. Yeast acts as a catalyst for the decomposition of hydrogen peroxide into water and oxygen, and a higher concentration of yeast increases the reaction speed, leading to a more vigorous and rapid release of oxygen. This results in a larger amount of foam being generated in a shorter time. Conversely, using less yeast will produce less foam and a slower reaction.
To create a giant elephant toothpaste recipe, you will need hydrogen peroxide, dish soap, food coloring, and yeast. Mix the hydrogen peroxide and dish soap together in a container. Add food coloring for color. In a separate container, mix yeast with warm water. Pour the yeast mixture into the hydrogen peroxide mixture and watch the foam expand, creating the "elephant toothpaste" effect. Be cautious as the reaction can be vigorous.
Any liquid will have the same effect on toothpaste as water.
It decreased the amount of estrogen being produced.
The dependent variable is the effect of an independent variable. For example, if a science experiment is done with plant growth under a certain amount of light, the height of the plant is the dependent variable because it depends on the amount of light.
The variable being studied in this experiment is the independent variable, which is the factor that is being manipulated or changed by the researcher to observe its effect on the dependent variable.
a toothpaste should have no effect on any diet, as long as you don't swallow it. -lance
In an experiment involving sugar water, the controlled variable would be the amount of sugar used in the solution. By keeping the amount of sugar constant while altering other factors, researchers can isolate the effect of sugar concentration on the outcome of the experiment.
In an experiment, the independent variable is altered, and the effect observed is the dependent variable, or outcome. The controlled variable is intended to be kept the same throughout the experiment so that changes in it do not affect the results.
The dependent variable in a homemade lava lamp experiment could be the amount of time it takes for the oil and water to separate, the number of bubbles formed, or the height of the "lava lamp" effect.
The manipulated variable in an experiment with a water rocket could be the amount of water or air pressure used to launch the rocket. This variable is intentionally changed by the experimenter to observe its effect on the rocket's performance.
The independent variable in this experiment is the amount of table salt added to the boiling water. The effect of adding salt to the water is to raise the boiling point of the water, therefore increasing the temperature at which the water boils.
In an experiment, your control variable will not be caused to vary by the experiment. Think of 'cause and effect'. The independent variable is the cause, the result is the effect, and the dependent variable is the one that you leave to be changed by the experiment.
