How does the independent variable affect the dependent variable?
The independent variable is the one the experimenter controls. The dependent variable is the variable that changes in response to the independent variable. The two variables may be related by cause and effect. If the independent variable changes, then the dependent variable is affected.
Does the Independent depend on the dependent?
The dependent variable is supposed to DEPEND on the independent variable.
Is the dependent variable always the opposite of the independent variable?
A dependent variable is a variable whose variations depend on another variable—usually the independent variable. An Independent variable is a variable whose variations do not depend on another variable but the researcher experimenting.
How do you differentiate between dependent and independent variables?
An Independent variable is a variable whose value never depends on another variable whereas a dependent variable is a variable whose value depends on another variable. The Independent variable is the presumed cause.
How do you identify an independent variable?
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.
What is independent variable in Research example?
The independent variable (IV) is the characteristic of a psychology experiment that is manipulated or changed by researchers, not by other variables in the experiment. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable.
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.
Can time be a dependent variable?
Time is always the independent variable. The other variable is the dependent variable (in our example: time is the independent variable and distance is the dependent variable).
Is sunlight a dependent variable?
Plant height is the dependent variable that responds to the change in the independent variable. Each plant is exposed to an equal amount of sunlight, so sunlight is the control variable. Both of those are also control variables, or constant variables.
Is water a dependent 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 height a dependent or independent variable?
the average height of adults might give you a graph as shown below. The independent variable is average height. The dependent variable is weight. For example, height might be an independent variable in the context stated above but a dependent variable in a study on the effect of nutrition on growth rates.
Why is time always an independent variable?
In this question, time is the independent variable and displacement is the dependent variable. The experimenter can select sampling times, but cannot necessarily predict the displacement that will be measured at each point. This defines time as the independent variable.
Is Vinegar an independent variable?
The amount of vinegar is the independent variable you are testing.
Is vinegar or baking soda the independent variable?
Independent Variable: The variable in the experiment that is controlled and changed to see the effect on the dependent variable. Say your experimenting with the amount of baking soda in a baking soda/vinegar volcano. The independent variable is the amount of baking soda you add.
What is the independent variable in the baking soda and vinegar experiment?
– The independent variable is the amount if vinegar and baking soda used in the experiment.
What is the independent variable in the bouncy egg experiment?
The independent variable is the types and size of eggs. The dependent variable is the height the egg reaches. The controlled variables are: The types of cups, zip lock bags, type of vinegar, the time each egg soaks in the vinegar, etc.
Why do eggs become bouncy in vinegar?
If you soak an egg in vinegar the eggshell will absorb the acid and break down, or dissolve. The calcium carbonate will become carbon dioxide gas, which will go into the air. What is left is the soft tissue that lined the inside of the eggshell. It will bounce!
How long do you leave an egg in vinegar to make it bounce?
Pour vinegar in until the eggs are completely submerged. At this point you will notice the egg is covered in little bubbles. Leave for 72 hours. Gently lift one of the (now rather delicate) eggs and gently rub away the shell.
What happens if you leave an egg in vinegar for too long?
What happens? Be careful, the eggshell will be a lot weaker! If you leave the egg in the vinegar for about 36 hours, eventually all the calcium carbonate will be dissolved by the acetic acid, leaving just the soft membrane and yolk behind.
How do I make my eggs Clear and squishy?
- First get permission to use kitchen equipment and eggs. Then put a raw egg (in its shell) into a bowl and cover it completely with vinegar.
- Wait two days, then drain off the vinegar. When you touch the egg, it will feel rubbery. Be careful not to break the membrane, and wash your hands after you touch the egg.
What happens when you put an egg in Coke for 24 hours?
After the Coca Cola and egg was left for a year, the soda reacted with the egg shell made up of calcium carbonate reacted with the acid and the result was surprising. All that was left in the bowl was some brown disgustingly gooey mess.
What does coke and vinegar do to an egg?
The little bubbles you see in the water are made of carbon dioxide gas; just like the bubbles from your vinegar and baking soda volcano. Once the shell is gone, the vinegar will cross over the semi-permeable membrane (through a process called “osmosis”) and slightly inflate the egg.
What liquids dissolve eggshells?
vinegar react with eggshells and make them dissolve, leaving the inside of the egg intact.
What happens when you put milk in eggs?
If you are in the habit of adding milk or cream while whisking eggs, you can stop. Now. Milk won’t make eggs creamier, fluffier, or stretch the dish out. What the milk really does is dilute the flavor of the eggs, making them rubbery, colorless, and something similar to what you would find at a school cafeteria.
Do u need milk for scrambled eggs?
When scrambled eggs are made right, they’re light and creamy all on their own (without the addition of milk, cream or cheese). And they usually need the help of cheese, hot sauce or ketchup to taste good. The good news is that it’s so easy to start making perfect scrambled eggs.
Why you should never put milk in scrambled eggs?
Never add milk to your scrambled eggs – it dilutes the flavour and makes them more likely to turn out rubbery.
What is the secret to making fluffy scrambled eggs?
The secret ingredient for perfect scrambled eggs is whisking the eggs thoroughly and vigorously before cooking them. Whisking incorporates air, which produces fluffier scrambled eggs, and fluffier eggs are the end goal.
