what the hell man
Because it is pointless doing an experiment if you are not going to be exact !
A variable in science 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. The independent variable is the one that is changed by a scientist in the experiment. The depended variable is what you measure in the experiment and what is affected during the experiment. A controlled variable is one which the researcher holds constant (controls) during an experiment.
your answerWell what you have to know FIRST is what they do BEFORE the experiment. What scientist do before an experiment is they observe what they are going to do. Then they come up with an HYPOTHESIS. An HYPOTHESIS is an educated guess. They write what they THINK is going to happen. Then they do their experiment. After they do that, they check their HYPOTHESISand if they guessed wrong, they don't cross the HYPOTHESISout, they learn from their mistakes, so they write what really happened during the experiment.

There are 7 steps. Ask, Identify, Choose, Assign, Manipulate, Measure, and Analyze
Record your observations during an experiment. This will be part of the data you collect.
The precautionary measure before and after the fire is to establish the source of the fire. Establishing the exit and how to put the fire is also important.

Precautionary measures are actions taken to prevent something else. A parent blocking off a staircase from a small child is a precautionary measure taken so that the child does not fall down the stairs.

You measure the ambient temperature before the experiment in case the experiment is sensitive to ambient temperature. You want to record all of the environmental factors that might affect the experiment before starting it. You measure the ambient temperature after the experiment for the same reason, and also in case the experiment affected the ambient temperature. Depending on the experiment, environmental factors may need to be considered when analyzing the results.

To measure heat effectively in a scientific experiment, use a thermometer to record temperature changes. Ensure the thermometer is accurate and calibrated properly. Additionally, consider using a calorimeter to measure heat transfer during reactions.
Liquid is often measured in a tall glass cylinder that has a graduated scale etched on its surface.
