In an experiment, water can be considered a continuous variable. This is because water can take on an infinite number of values within a given range, such as volume or temperature, and can be measured with varying degrees of precision. Discrete variables, on the other hand, consist of distinct, separate values, which does not apply to water in most experimental contexts.

list some variables that can change in an experiment?
It can be, it depends on your experiment. Independent variables are the variables in an experiment that will not change. If you want to do an experiment that tests how something reacts with water, then starting with a clean controlled water sample for each test would be necessary and an independent variable. Conversely, if you were testing the cleanliness of multiple water sources, then the ideology of clean water would be your dependent variable, which would change upon each testing. WIth your given information I cannot say whether or not you would want water to be either a dependent or an independent variable for your experiment.
Quick way to think about the difference: Discrete variables have to be measured in whole numbers; typically you can't have fractions of discrete variables. Continuous variables can be measured, if desired, to very fine levels of accuracy and are typically not thought of as being measured in whole numbers. Example: How many drinking glasses do you own? Your answer will be a whole number. A fraction of a drinking glass has no meaning, unless you're counting broken glasses. How much water is in that glass? Your answer could be finely measured over any number of different scales, to any number of decimal places. Amount of water would be a continuous variabe in this case. There are various ways to use and measure variables, so it depends on your research need. For example, water might be a discrete variable if you are using 8 ounce sealed bottles of water as your units.

Manipulated variables are variables that a scientist deliberately adds in to tweak the outcome of his or her experiment. For instance, a scientist may choose to add certain compounds into a pot of water to see if it may affect the boiling point.
"Continuous" means there's no smallest piece. If you pick two amounts, then no matter how close together they are, there's always an amount between them. Amounts of time, water, and temperature are continuous. "Discrete" means there is a smallest piece. If you pick two amounts and they're close enough together, there's no amount between them. Amounts of beans, cars, and chickens are discrete.

The experiment consisted of copper pennies, 5 small beakers, and dropper bottles of: dish soap, water, ethanol, and baby oil. We had to drop these liquids onto pennies and see which could hold the most. So, what would be the manipulated, responding, and controlled variables in this experiment?
The variables in a blobs in a bottle experiment may include the type and amount of materials used to create the blobs, the size and shape of the bottle, the temperature of the water in the bottle, and the amount of time elapsed to observe the blobs forming and reacting. These variables can be manipulated to study how they affect the formation and movement of the blobs in the bottle.
The volume of water loss each day through a leaky faucet is considered continuous. This is because the water can drip at any rate, and the amount lost can vary continuously over time rather than being restricted to distinct, separate quantities. The flow of water can be measured in infinitely small increments, making it a continuous variable.
