List the steps of the scientific method
What is ask a question, research, experiment, record results, conclusion
Scientists communicate their results by publishing their work. Why is it important for scientists to do this? A. to learn from each other B. to keep their work secret C. to compete with other scientists D. so the experiments are not repeated
What is A. to learn from each other

Scientists make predictions about the natural world and how it works. Scientists often carry out experiments that are based on predictions. Tell what an experiment is and why it is important?
An experiment is a repeatable set of steps designed to solve a problem or answer a question. Scientists conduct experiments and gather evidence to check whether hypotheses are supported. Experiments help explain the natural world.
