The scientific method is a way to ask and answer scientific questions by making observations and doing experiments. The steps of the scientific method are to: Ask a Question Do Background Research Construct a Hypothesis Test Your Hypothesis by Doing an Experiment Analyze Your Data and Draw a Conclusion Communicate Your Results

All matter is composed of very small particles called atoms. All atoms of a given element are identical. Atoms cannot be created, destroyed, or subdivided. In chemical reactions, atoms combine with or separate from other atoms. In chemical reactions, atoms combine with each other in simple, whole-number ratios to form combined atoms.
