What do we mean when we say we are studying a subject scientifically? Or what’s the correct attitude towards science? We should be objective, not superstitious.Answer these questions.2. What’s the correct way to prove a scientific idea? We should design experiments to test it for several times. Then we can analyze the results and draw a conclusion at last.3. What are the most important skills we need to be real scientists? Careful, objective and logical, draw conclusions from the experiments and not impose conclusions on the data.
