Because it is pointless doing an experiment if you are not going to be

Record your observations during an experiment. This will be part of the data you collect.
So that you are NEVER confused at anytime within the conduction of the experiment.
Observation and record keeping are important as you will need to redo an experiment many times to prove that it actually works.
so others can repeat it and see if you did it right
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.

He recorded the results of his experiment by documenting observations, measurements, and data collected during the experiment. These results were typically recorded in a lab notebook or electronic record. The results were then analyzed and interpreted to draw conclusions and determine the significance of the experiment.

The temperature recorded in a freezing point determination experiment is the temperature at which the substance changes from a liquid to a solid state. This freezing point is an important characteristic of the substance and can be used to identify the substance or assess its purity.
