What are the 3 variables used for an experiment?

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.

How do we identify the 3 variables in an experiment?

The variables in a study of a cause-and-effect relationship are called the independent and dependent variables.

1. The independent variable is the cause. Its value is independent of other variables in your study.
2. The dependent variable is the effect. Its value depends on changes in the independent variable.

How do you measure electrolytes?

The electrolytes – urine test measures electrolytes in urine. It tests the levels of calcium, chloride, potassium, sodium, and other electrolytes….Each electrolyte can be measured separately, such as:

1. Ionized calcium.
2. Serum calcium.
3. Serum chloride.
4. Serum magnesium.
5. Serum phosphorus.
6. Serum potassium.
7. Serum sodium.

What is the conductance of Gatorade?

Gatorade had a voltage of 3.51V and was most conductive of all the drinks. The reason Gatorade is so conductive is because of the salt (electrolytes) added to the solution. These electrolytes are redesigned to help athletes replace salt they lose from sweating and salt.

What is the variable that you change?

Identify the variables Independent variable – the variable that is altered during a scientific experiment. Dependent variable – the variable being tested or measured during a scientific experiment. Controlled variable – a variable that is kept the same during a scientific experiment.

What are the types of variables?

Types of variables

• Independent variables. An independent variable is a singular characteristic that the other variables in your experiment cannot change.
• Dependent variables.
• Intervening variables.
• Moderating variables.
• Control variables.
• Extraneous variables.
• Quantitative variables.
• Qualitative variables.

How do you identify variables?

An easy way to think of independent and dependent variables is, when you’re conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as the effect.

What is variable and its types?

Categorical variables represent groupings of some kind. They are sometimes recorded as numbers, but the numbers represent categories rather than actual amounts of things. There are three types of categorical variables: binary, nominal, and ordinal variables. Binary vs nominal vs ordinal variables. Type of variable.

What are the symptoms of low electrolytes?

Symptoms of electrolyte disorders

• irregular heartbeat.
• fast heart rate.
• fatigue.
• lethargy.
• convulsions or seizures.
• nausea.
• vomiting.
• diarrhea or constipation.

Does Gatorade have electrolytes?

Does Gatorade have electrolytes in it? Yes. Gatorade is an electrolyte-rich drink that helps replace electrolytes that are lost in the body during exercise. Electrolytes can be lost through sweat and urine, and are used in daily bodily functions such as regulation of the nervous system.

Is orange juice an electrolyte?

100% orange juice naturally contains a high percentage of water – almost 90 percent. 100% Orange juice also contains electrolytes, such as potassium, which aid in fluid balance.

How are electrolytes measured in a science project?

To measure the electrolytes in this science project, you will use a multimeter. A multimeter is an electronic device that measures voltage, current, and resistance. You can learn more about these terms in the Science Buddies Electronics Primer. For this project, you will use just the ammeter part of the multimeter. An ammeter measures current.

What happens when you increase the concentration of electrolytes?

If you increase the concentration of electrolytes in a solution, the conductance of the solution also increases. In order to measure a current in the solutions, you have to apply a voltage. You will use a 9 volt (V) battery to supply the voltage.

How are voltage and conductance of an electrolyte measured?

The symbol for conductance is G and it is measured in units called siemens (S). The symbol for current is I, and it is measured in amperes (A), commonly called amps for short. The symbol for voltage is V and it is measured in volts (also abbreviated V).

Why are electrolytes maintained in a narrow range?

The maintenance of electrolytes within this narrow range is due to the body’s homeostatic mechanisms, which control the absorption, distribution, and excretion of water and its dissolved electrolytes. To measure the electrolytes in this science project, you will use a multimeter.
