What are dependent and independent variables, and on what scale of a graph do you record each?
The independent variables are the different test subjects that you will be testing. The dependent variable is the actual measurement that you take for each test subject for example, the elapsed time or a distance measurement. The independent variable is plotted on the X axis, while the dependent variable is plotted on the Y axis. 8. Define and give an example of each: Element, Mixture, Compound, Atom. An element is a substance that can not be broken down into even simpler substances by chemical reaction. Examples are hydrogen and oxygen. An atom is the smallest piece of an element that can exist and still have the properties of that element. A mixture is a combination of two or more substances mixed together but not bonded together. For example, salt and sand can be mixed together but do not react with one another or bond together. A compound is a substance containing two or more elements bonded together into a new substance with different chemical properties. 9. Draw an Bohr model ill
