Experiments and observations are both methods used in scientific research to gather information about the world. They both involve collecting data, testing hypotheses, and drawing conclusions based on evidence. However, experiments involve manipulating variables to test causal relationships, while observations involve simply watching and recording phenomena without interference.
Glass cylinders are commonly used in lab experiments because of their transparency, allowing for easy observation of reactions or measurements of liquids. They are also chemically resistant and can withstand a range of temperatures, making them versatile for various experiments. Glass is also easy to clean and sterilize, ensuring that experiments are not contaminated.
Francis Bacon is the English philosopher known for conducting experiments to make predictions. He is often considered the father of the scientific method for his emphasis on empirical observation and data collection.
Physics is considered a a experimental science because much (70%) of physicists work is conducting experiments. Experiments are used to test relationships and theories. The result of the experiments weed out theories and support theories, other experimetns test rhe range of a relationship.
Galileo Galilei is credited with performing many experiments to measure the rate at which objects fall. He conducted these experiments by dropping objects of different weights from the leaning tower of Pisa to show that all objects fall at the same rate regardless of their mass.
Wooden blocks are commonly used in physics experiments to study friction, momentum, and forces. They are used to demonstrate concepts such as inclined planes, pulleys, and collisions. Wooden blocks provide a simplified and easily manipulable system for students to observe and understand physics principles.
Theory
observation are made in a living mouse
The hypothesis supported by thousands of scientists states that the same observation or phenomenon is reproducible and valid across multiple experiments and studies. This consensus among scientists adds credibility and strength to the hypothesis.
analysis of data, experiments, observation
observation hypothesis experiments result further hypothesis further experiments results and theory
The scientist must propose an idea and document it with experiments that prove it. The experiments must be repeatable by others and the same result must be obtained by them
Science- Is the systematic body of knowledge obtained from experiments,observation and studies.
Aristole
based on observation of what is wrong with the work of other scientists
No. Your observations are what you see; conclusions are what you see using outside knowledge. Some experiments cannot possibly be concluded at once in one go with all the different observations.
It's "empirical" not "emperical".The word empirical denotes information gained by means of observation or experiments.
A hypothesis is based on you observation, and experiments on what you are going to do. If your hypothesis is wrong or doesn't match the results you had, you would need to modify it, so basically a hypothesis deals with prior knowledge.
