Our senses, such as sight, hearing, touch, taste, and smell, are used to observe and perceive the results of an experiment. Instruments such as thermometers, microscopes, balances, and pH meters are used to measure and quantify different aspects of the experiment, providing more accurate and detailed data.
Instruments and our senses are used to collect and analyze data during an experiment. This data is essential for drawing conclusions and making observations about the experiment's variables and outcomes.
Yes, the purpose of an experiment is usually to test a hypothesis and determine whether it is supported by the data collected during the experiment. The experiment is designed in a way that allows researchers to make observations and draw conclusions about the hypothesis under investigation.
A more accurate way to make observations of an object is to use scientific instruments like microscopes, spectrometers, or sensors to gather data in a controlled and precise manner. This allows for more objective and detailed observations compared to relying solely on human senses.
Ernest Rutherford was the first scientist to propose that protons reside in the nucleus of an atom, based on his gold foil experiment in 1911. Neutrons were later discovered by James Chadwick in 1932.
To make an experiment more reliable, it is important to have a large sample size, control for confounding variables, and ensure replicability by conducting the experiment multiple times. These factors reduce the impact of chance and increase the validity of the study findings.

Scientists use measuring instruments whenever the can because everything cannot be observed by the senses so measuring instruments are needed instead.
When you use your senses to obtain information, you are making an observation. This is a major part of science where you use your senses or the readings of instruments to directly acquire information from a primary source.
Counting or measuring instruments in a study or experiment.
Scientists make observations to help them make a hypothesis or collect data during an experiment.
