Name: ____________________________________ Block #: _____________ Date: ____________________ DENSITY OF SOLIDS LAB Equipment Needed: Triple Beam Balance Scales Electronic Scales Graduated Cylinders Density Specimens Calculators Water Rulers Purpose: This lab emphasizes analytic measurements, experimental technique, and problem solving, in determining measurements. You will determine the mass and the volume of given materials to find their density: DENSITY = MASS / VOLUME Volume of Rectangle = L x W x H Method: You will be placed into groups to perform this experiment. You will find your equipment at each of your workstations. To find the density, you will need to measure mass and volume. If your specimen has smooth, measurable sides, (like a block) measuring with a ruler to find the volume will be the most accurate (V = L x W x H). Otherwise you will need to find the displacement of the object to measure its volume. Be as accurate as possible. Objective: ______________________________________________________________________________ ______________________________________________________________________________ Hypothesis (Which solid object do you think will be the densest and the least dense?): ______________________________________________________________________________ Results: Specimen Mass (g) Volume (mL) or (cm3) Density (g/mL) or (g/cm3) Name: ____________________________________ Block #: _____________ Date: ____________________ Thought Questions: (Use Complete Sentences!) 1) What is the definition of density? (you may use your textbook) ______________________________________________________________________________________ ______________________________________________________________________________________ 2) The density of a large block of wood is __________________ a small block of wood. *TRICKY* a. Greater than b. The same as c. Less than 3) Which one of the specimens you listed in your data table will float in a beaker of water and which one will sink? EXPLAIN YOUR REASONING!!
