The type of rain barometer/barometer used would be the independent variable. This type of experiment would give you quantitative results. These suggestions should help you think of other weather experiments you can do.
Is water an independent variable?
The dependent variable is usually what scientists measure in an experiment. … In this case, the amount of water is the independent variable because that is what you’re changing in the experiment: one seed gets a lot of water and the other seed only gets a little water.
Is rainfall independent or dependent variable?
Therefore, rainfall is the dependent variable and time of year is the independent variable. In some graphs, you may have more than one dependent variable, but never more than one independent variable.
Is acid rain a independent variable?
Acid rain usually has a pH between 4.2 and 4.4.
|Research Question:||How does pH affect plant growth?|
|Independent variable: pH of water Dependent variable: Height of plant||Controlled variables: Type of plant Germination conditions|
What will be my independent variable?
There are two types of variables-independent and dependent. … Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example, someone’s age might be an independent variable.
Why is time a dependent variable?
Time is usually viewed as the independent variable for the simple reason that it doesn’t depend on anything else. Time simply ticks by at the same rate wherever you are (in non-relativistic context), independent of other variables so it doesn’t make sense to express time as a dependent variable.
What are the 3 types of variables?
A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled.
Is temperature an independent variable?
For example when examining the influence of temperature on photosynthesis, temperature is the independent variable because it does not dependent upon photosynthetic rate. … The dependent variable is dependent upon changes in the independent variable. For example, photosynthesis is dependent upon temperature.
Is time a independent variable?
Time is a common independent variable, as it will not be affeced by any dependent environemental inputs. Time can be treated as a controllable constant against which changes in a system can be measured.
Is rain dependent on temperature?
As average temperatures at the Earth’s surface rise, more evaporation occurs, which, in turn, increases overall precipitation. Therefore, a warming climate is expected to increase precipitation in many areas.
How do you test for acid rain?
To measure the potency of acid rain, scientists test the pH of collected cloud water. The pH tests show how acidic or basic something is. The pH scale rules from 0 to 14. Seven represents levels that are neutral, while lower numbers are more acidic and higher numbers are more basic.
What is an acid rain?
Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms. This can include rain, snow, fog, hail or even dust that is acidic.
How do you test for acid rain in plants?
- Fill each pot with potting soil. …
- With a permanent marker label one pot ‘Acid rain’ and the other pot ‘Normal’.
- Water both pots and place them under a direct source of light.
- Repeat watering every day or every other day (depending on seed type) until each pot has a sprout with leaves.
Which is the dependent variable?
The dependent variable is the variable that is being measured or tested in an experiment. 1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores, since that is what is being measured.
What is dependent and independent variable in Research example?
In a study to determine whether how long a student sleeps affects test scores, the independent variable is the length of time spent sleeping while the dependent variable is the test score. The independent variable in your experiment would be the brand of paper towel. …
What is dependent and independent variable in research?
In analytical health research there are generally two types of variables. Independent variables are what we expect will influence dependent variables. A Dependent variable is what happens as a result of the independent variable.
