2. Some guidelines… You will be finding the density of two different substances – one solid and one liquid (DI water). You will need to take multiple trials of different amounts/sizes of your substance. Make sure that you are using the same substance for each trial! Data should be in a data table. We will graph it tomorrow. You are free to use any of the equipment on the cart. If you want to use something that is not there, ask me and I’ll get it.

3. Analysis Graph your data for both substances. Use the best graphing practices as a reference! Find the slope of both graphs. Use the given data table to identify your solid. Find the percent error of your experiment using the following formula: Write a RERUN conclusion
