Lab: Exploring Density
This laboratory provides you with a more in-depth look at density of materials and some of the various laboratory methods utilized to determine the density of solids and liquids. You will have an opportunity to investigate density relationships for different solution concentrations as well as the concept of buoyancy as related to density. You will also consider the accuracy and precision of some of the densities you determine. You will be making and using sucrose solutions in this lab, graphing the data obtained and predicting the sucrose content in a beverage. These solutions, if left on surfaces or apparatus, will leave a sticky residue. Cleanliness in the laboratory is important! Make sure to have the Introduction to GraphingInvestigation Manualavailable to assist you in setting up your graphs!
